Another interesting application of Geon polyvinyl materials

THIS "ocean" is constructed from
an unsupported sheet of plastic
material made from Geon polyvinyl
resins. This plastic offers a combina-
tion of properties which could hardly
be obtained from any other material.
It's waterproof and mildew-proof
and it's smooth, flexible, tough, and
long-lasting.

Such qualities make the Geon mate-
rials equally suitable for wire insula-

tion or clothesline or upholstery. In fact,
no one has yet been able to predict
how many practical, money-saving,
quality-improving or cost-cutting
things Geon can do. This we know:
Just as it adds to children's fun and
safety in the back yard it can create
new benefits to consumers and new
markets for manufacturers.

How can you use Geon? It can be
extruded, pressure or injection mold-

ed, used as a coating for paper or
tiles, calendered or cast into sh
or film.

We make no finished products f
GEON or from any of our 01
raw materials. However, we will
glad to work with you on any spe
problems of application. We are
ticularly interested in developing i
end uses for these materials. For rr

The Torpedo that's never "fired"

IT isn't likely that the torpedo type screw
shown above will ever be "fired" off the
job . . . it's too valuable a production tool
. . . after years of profitable service it will
probably be replaced with a duplicate.

Part of the success of this screw is its de-
sign ... the ability of its nose or "torpedo"
to mill the material and to transfer heat
quickly. The torpedo screw, a patented and
exclusive NRM design, is considered a
"must" for the proper extrusion of Cellulose
Acetate, Cellulose Acetate Butyrate, Ethyl
Cellulose and Polystyrene.

But, like all other NRM screws there are
many factors that make it so outstandingly
different.

All NRM screws are machined and finished
on specially designed NRM equipment
to eliminate the non-uniformity
problem that is common with the

older, customary hand finishing methods.

In NRM's completely equipped screw
finishing shops, screws are continually in-
spected in every stage of machine finishing to
assure concentricity, precision uniformity of
flights and the streamlining of flight surfaces.

Because extreme accuracy is maintained
through every machining operation, NRM
screws are characteristically free of pul-
sation.

Long life is assured by a unique screw
hardening process developed by NRM en-
gineers to provide a uniform^hardness to
flight lands and bearing surfaces, together
with high strength and toughness.

NRM engineers are available to help you
obtain better extrusion production through
the use of better equipment. Write us about
your problems and we will work with you
to obtain the results you desire.

Note: The torpedo screw is patented.

THERE HAS BEEN an interesting trend in the
publicity releases on company personnel. Where-
as announcements used to be chiefly of appointments
of new research men in the laboratory or production
men in the plant, more and more of them in recent
months are covering additions to and shifts in sales
staffs. This would seem to be an accurate reflection
of the trend of thinking in the trade today of thinking
that is being translated into action.

EXTENSIVE USE of plywood as sub-flooring,
wall- and roof-sheathing has shown that the
material is well-adapted for structural components,
according to a recent announcement by American
Homes, Inc., which is one of the country's largest pro-
ducers of prefabricated homes. The same experience
has been reported by other companies in this field.
Certain types of plywood are in fact said to be as
strong as, if not stronger than, any other construction
material. About a third of the total lumber used in
the parts American Homes produces for houses is ply-
wood, and houses range in size from a small home to a
garden-type apartment. Synthetic resins, of course,
do the bonding job which help to give plywood its
valuable characteristics.

WHAT IS THE SALES cost of a package? If a
manufacturer charges the total cost of his con-
tainer to sales, it may be so high that he will think
twice before spending more money to improve it.
However, there are three functions of a package which
may not properly be considered as strictly sales aids:
(1) mechanically protective function, as in keeping
cigarettes from being crushed in shipment, (2) dis-
tributive function, as in packaging rice as a means of
getting it to the consumer, (3) preservative function,
as in retaining the moisture of foods. It is only after
these three essential functions are discharged and
further design effort is expended on a package by way
of making it more colorful or more interesting in shape,
that its sales function, properly speaking, begins.

This interesting analysis was made by E. A. Throck-
morton, president of the Container Laboratories, Inc.,
at the recent forum of the Packaging Institute held in
New York. To make his point more concrete, Mr.
Throckmorton said :

"I think all of you can visualize a package for ciga-
rettes which has the distributive function as a primary
purpose ; it may be also mechanically protective ; it may
be also preservative ; but it may be a very plain-looking
package. It might be gray or brown instead of white ;
it might be rough instead of smooth; it might not be
shiny ; it might not be printed attractively in a number
of colors.

"None of these things is essential to the sale of the
cigarettes or to the handling of cigarettes to the con-
sumer. The cost of making the surface of the package
white instead of gray, or clean instead of dirty, or shiny
instead of dull, or multi-colored instead of one color
small type, is a sales cost, and I think that it" we make
such a definition in our minds it will help many people
to decide how much should be spent on a package."

IN THE DECEMBER issue of Plastics we published
an article on a first application of inflated vinyl
film for display purposes, pointing out how this opened
up a new field for that type of plastics. Hardly had the
article been set in type than we got word of a develop-
ment in a direction we had not foreseen the use of
inflated vinyl forms in place of the expensive, cumber-
some composition figures the garment industry has
been struggling along with (see page 18, "Inflated
Vinyls Make Display Manikins"). We mention this
here as a reminder of the vigorous youth of the in-
dustry, in which a new idea proliferates rapidly in all
sorts of ways and alert end-users constantly open up
a variety of new applications for the many types of
plastics materials.

WHAT MANAGEMENT may and may not say
to its employees on the subject of unions, union
leaders and employee membership in unions is a deli-
cate matter, but under the Taft-Hartley law it has
definite rights to declare its views on these subjects,
provided that. . . . These provisos are the subject of
Bulletin No. 275 issued by SPI as part of its service to
members in the field of labor-management relations.
We do not mean to imply by "provided that" that there
is a joker somewhere. There isn't : the bulletin simply
lists "Statements Not Permitted" and "Permitted
Statements" so that there should be no ambiguity
about it. END

THE VAST IMPROVEMENTS made during the last
10 years in the design of hearing aids, in which plas-
tics have played an important role, point the way to manu-
facturers of other small precision instruments where the
examples of light weight, simplification, compactness and
lowered costs can be applied. The modern hearing aid is
worn today by greatly increased numbers of people because
engineers have ingeniously applied to it new ideas, new
materials and new methods.

The modern device dates back to the introduction during
the 1930's of the electronic tube instrument, which is essen-
tially a miniature public address system, consisting of a
microphone which picks up sound, an amplifier and a re-
ceiver fitted to the ear which serves as a loudspeaker. Origi-
nally these components, plus a battery case, were worn or
carried separately, connected one to the other with wire.

JANUARY 1948

PLASTICS

Progress in hearing aid development shown with new "Sonotone
900" instrument compared to the "Perceptron" of ten years ago

Although the first electronic aids provided a marked im-
provement over previously available devices, they were both
bulky and unattractive.

The first steps to overcome these disadvantages involved
the application of molded phenolic cases, with the advan-
tages of light weight, resistance to body acids, and comfort
in wearing. Use of phenolic in the housings was supple-
mented internally by punched laminates to provide electrical
insulation without sacrifice in weight or bulk.

Readier acceptance of hearing aids, particularly by
women, was induced by the development of acrylic ear molds
custom made to fit the ear. These ear pieces, often tinted
flesh color, provided concealment of what would otherwise
be the most conspicuous part of the device. Today, these
and other earpieces for women are often decorated to re-
semble an earring, again through the use of plastics.

All-in-One Instrument

The inconvenience of wires was lessened with the adop-
tion of skin-colored vinyl coated wire which is smooth to
the touch, highly flexible and chemically resistant to both
body and battery acids. With the development of extremely
small electronic tubes and the war-spurred creation of mini-
ature high power batteries, remarkable reductions in size
and weight were made possible. These new components,
plus use of molded and fabricated plastics, permitted the
production of the all-in-one instrument in which battery
case, microphone, and amplifier are combined in one slender
unit weighing less than a half pound. People who were
sensitive about their handicap and put up with it rather
than toting around cumbersome devices, now accept the
modern hearing aid, which is so markedly improved in
appearance and function. Although virtually all products
are included in a price range of $75-$200, keeping them

beyond the reach of the lower income brackets, the middle
class market has been opened up.

An excellent case study in the role of plastics in these
sound magnifying devices is afforded by Paravox, product
of Paraphone Hearing Aid, Inc., Cleveland. Starting out
five years ago as an all-in-one type, it has been steadily
modified to reduce the number of parts, overall size and
operating cost while at the same time gaining an increased
life span. In the latest model, which is about the size of a
spectacle case and weighs only six ounces, including batter-
ies, there are no fewer than 22 components made of six
different types of plastics: butyrate, acrylic, phenolic lam-
inate, molded phenolic, polyvinyl chloride and polystyrene.

High Uniformity of Performance

The Paravox is said to have a high uniformity of per-
formance that is, there is little variability from unit to
unit; and this achievement is attributed to the chassis
molded of butyrate (Tenite II). This chassis may be con-
sidered as a kind of internal housing, but it is not merely
a shell. Rather, it is an intricate thing of recesses and cavi-
ties within which the functional parts of the instrument are
mounted. None of them projects beyond either the top or
bottom surface of the chassis even the wiring is contained
in a molded-in channel. The parts are therefore not in con-
tact with the instrument case, and so are protected from
direct shocks suffered during ordinary use. Thus, when the
chassis is removed from the case for servicing, they cannot
be damaged even by "reasonably careless" handling.

The chassis itself is strong enough to withstand far more
punishment than it can ever meet up with in normal use.
According to an objective testing laboratory, several sam-
ples, lying on their flat side, did not develop a crack until
they were subjected to 1480 Ib. Placed inside of a brass
case, they stood up to a load of 2450 Ib. A stress of 570 Ib
on the edge of the chassis (a position it would not ordi-
narily assume) bulged the sides without causing any visible
cracks.

Molded Internal Chassis

The molded internal chassis is the answer to more than
one problem. To understand this, it is necessary to consider
the basic problem of the device as a whole : the need for a
design that would lend itself to quick service. A chassis
which could be easily removed and replaced while the cus-
tomer waited, was indicated. Bearing in mind that trained
technicians would not be available at the point of service
and that a salesman would be the contact with the customer,
the engineers realized that it was necessary to eliminate
entirely the need for soldering wires, replacing of small
parts and the use of any tools by the dealer.

A case of a very thin light metal which could be readily
disassembled without tools called for support over a large
part of its surface, and it was decided that such support
must come from the inside. Final solution of this problem
was deferred in order to study the chassis design and its
effect on the design of the case.

This, as it turned out, proved to be the major problem, for
the ideal chassis should be easily removable without discon-
necting wires or detaching screws, should completely pro-
tect all parts from negligent handling, should lock and in-
sulate them to prevent electrical short circuits, and finally
should provide the necessary support for the case.

According to the company, the most common type of
chassis used in hearing aids is punched from phenolic lam-
inate sheet. This has excellent electrical properties and is
strong enough to mount the many parts which make up the
device. The drawback is that the parts so mounted, on one
or both sides of the laminate, are exposed and, being deli-
cate, are easily damaged in handling.

Such a chassis could hardly be designed to serve also as

PLASTtCS

JANUARY 1948

a supporting member for the case without an elaborate and
expensive machining job, for the support must be distributed
evenly over the interior surface of the case and follow its
contours perfectly. Clearly, the solution lay in a molded
chassis, the outside contours of which could be matched
with the inside contours of the metal case.

The latter was then designed with a channel along the
edge of its front section, and the rear portion was provided
with flanges, permitting it to be engaged with the front by
a sliding action.

A clear, faintly rose-tinted butyrate was chosen for the
chassis, as noted, because of its dimensional stability and
resistance to mechanical breakage as well as to the chemical
action of battery and body acids.

Although this kind of chassis, calling for a complex mold,
is obviously more expensive than a punched piece of stock
laminate, the company believes that "the elimination of a
number of mounting devices, the great saving in the Service
Department and last, but by no means least, the satisfied
customers, will far offset the difference in cost." (Inci-
dentally, the company finds the laminate is still indispensable
for some applications, as noted later on.)

Precision Necessary

The mold for the chassis was designed and manufactured
by Vlchek Tool Company, Cleveland, Ohio, working in con-
tinuous cooperation with Paraphone engineers. With the
great number and intricacy of cores required to fill the
recessions of the mold at various depths, and with heavy
sections adjacent to sections as thin as .025", it is plain that
the machining and fitting of the mold parts had to be done
with watchmakers' precision, and tool tolerance is said to
have been .0005".

In the injection molding operation, which is carried out
on 6-oz Lester presses, the mold is given a preliminary
heating in order to allow the thin sections to be properly
filled. Full ram pressure of the machine is employed, and
the mold is held under pressure until it cools somewhat, in
order to prevent sink marks in the heavy section. The die
face must be checked more often than in the case of less
complex molds, for it must be maintained with utmost ac-
curacy to avoid flash.

The array of cores in the chassis are all cam operated. It
is interesting to note that in the molding of the angle ear
plug (Vlchek produces all the Paradox molded compo-
nents), a curved core pin is used.

Plastics Offer Many Advantages

In the caption of an accompanying illustration, the other
plastics components used in Paravox are summarized. The
reasons for the choice of the particular plastics in each case
are of prime interest.

Aside from its use in the chassis, which has already been
covered, butyrate is also the material chosen for five other
parts. Although the company felt that acrylics might be
more attractive, it decided that the superior strength of
butyrate should not be sacrificed for appearance, especially
in such components as the chassis and the earphone cord
plugs, where the thin rails which fit into a tight socket
might be easily broken if made of acrylic.

A flesh-colored opaque Lucite acrylic was selected, how-
ever, for the air receivers, chiefly for its non-toxic qualities
as well as for its appearance, while transparent Lucite was
chosen fer its excellent optical properties as the top of the
display case in which the instrument is packaged. Although
the bottom half of the display case is molded of polystyrene
primarily for economy sake, the gold and ivory mottles
used make an attractive contrast with the clear acrylic.

Flesh-colored polystyrene is molded for the body of the
volume control wheel and control switch wheel in order to

* WHAT'S NEW? EVERYTHING.'

<J So many new developments are whispered around
the trade that no one can be sure of his product, his
mold or material. Just as nitrocellulose has supposedly
been in the last twitches of death for the past 10 years,
reports come from France of a new nitrate compound
with fire-resistant qualities; from an American com-
pany comes word of a thermosetting resin compounded
with rubber chemicals having an impact equal to that
of the cellulosics, new heat-resistant thermo-plastics,
new dimensionally stable compounds of many types
and all working toward a universal material. It will not
be long before everyone will use just one material for
any purpose. And then, how simple will our prob-
lems be !

q As a small independent producer of molding pow-
ders, your commentator threw up his hands in dismay
at each announcement of a new material soon to re-
place existing ones. This happened al least once a
week. He was only consoled by a frequent visit to the
grave of John Wesley Hyatt who, sitting up in his cof-
fin, thoughtfully wondered why a passe plastics like
nitrate was forever being expanded. Actually, every
development broadens the field rather than narrows it,
providing new hope, greater opportunity and a stimu-
lant for further development.

* 1948 CREDIT PICTURE

<J The credit manager is going to earn his salary in
1948. Although projections indicate that this will be
an outstanding year for plastics, no year since 1937
appears more hazardous from the financial man's view-
point. In 1947 we observed some failures and many
refinancings, largely among companies established less
than 10 years. Credit men respect enterprising busi-
nessmen because they know it is their daring and their
optimistic and exciting outlook on the future that pro-
moted the industry to its present enviable position. Most

businesses started in a small way. No one denies
the necessity for taking long chances. When these
risks turn out all right, the armchair quarter-
backs call them "brilliant" ; when they go into re-
verse, they call them "stupid." Only a bit of luck
forms the imaginary line separating the success-
ful from the unsuccessful.

<I Unfortunately, credit men, as trustees of
other people's money, can only back what is con-
sidered sound business. When they guess wrong-
ly, their unsympathetic course is to sue, foreclose
or make unfriendly demands.
<I When the recession came in early 1947, there
was sufficient accumulated fat to maintain com-
panies through the balance of the year. How-
ever, in 1948, the fat is not there. Taxes on high
1946 profits have been paid ; operating losses like-
wise depleted cash. Now, unless operations are
profitable, more and serious failures are inevit-
able. The Federal Reserve Bank reported cor-
porate profits as probably reaching their peak last
June, but showing declines during the last six
months. A composite profit curve of the plastics
industry, it is estimated by many financial men,
will show up poorly for the entire year 1947, with
the last quarter better than others due to the
Christmas surge.

<J But the once glamorous plastics picture is now
one of a cold gray dawn. The premium, if there
is one, will be on sales imagination, engineering
know-how and management efficiency. These
factors will determine the credit man's extensions
when balance sheet ratios are unfavorable.

* BASIC CHEMICALS UP

<J On every hand raw chemicals for plastics have
been jolted by higher prices petroleum, coal and
other natural products. About the only elements
unchanged are air and water two ingredients
well advertised as raw materials for plastics.
Plastics materials have resisted the pressure, but
even they may be forced to higher levels. There-
fore, long-term contracts without firm commit-
ments for materials bear consideration.
<I The fact that polythene molding powder was
cut from 50^ to 46ff per Ib, and colored acetate
from 49^ to 44^, is misleading. The former, a
IH-W material, has justified lower prices through
expanded consumption; the latter was driven
down by competitive reasons.

* INFLATION EVEN IN PL4STICS

CJ For 1948, the biggest problem facing us all is
inflation. You are unique if you don't have a
theory to curb it. You are unique if you have
the courage to do anything about it. Federal Re-
serve Board Chairman Mariner Eccles made a
sound but austere proposal in December, which
fell on deaf ears. He suggested cutting purchas-
ing power by curbing credit, and thereby making
it difficult for people to buy. Chas. E. Wilson,
G.M.'s president, advanced a sound program at
NAM's New York meeting, in which the most
important suggestion was to extend the work

How to HANDLE a Cleaver

Tenite handle coupled with a cutlery-steel blade won
this household cleaver a place in the Museum of Modern Art's
annual exhibit of "100 Useful Objects of Fine Design."

Tenite is well suited to such modern functional design.

It is quickly formed by injection molding, or by continuous extrusion.

Finished, it is tough and will stand hard use.

Its smooth, splinterfree surface is easy on hands.

In addition, Tenite color and luster provide smart appearance.

Tenite is a favored handle material for all sorts
of products including saws, lawn mowers, lanterns,
refrigerators, and toothbrushes and is adapted to many
other uses besides. For a 32-page book on Tenite,

AN INFLATED VINYL manikin and a shoulder and bust
form of the same material, for the display of ready-to-
wear clothing, have been fabricated by Barbera Plastics
Originals, New York. These are so much more economical
and easy to handle than the conventional display forms that,
within a few weeks after they were announced, the firm was
flooded with inquiries from dress manufacturers, retailers
and -display managers in every part of the country and
abroad, according to Edmund Barbera, head of the com-
pany.

Both types of vinyl forms full or bust size can be in-
flated and deflated like a balloon by use of lung pressure, a
small bellows, or a vacuum attachment, and when not in use
can be folded away to occupy a few inches of space. When
inflated an operation which takes only 30 seconds they
emphasize the details and lines of a dress, sweater, or
blouse with all the advantages of a human figure.

Weighing less than a showroom hanger, the collapsible
forms are manufactured in all sizes from 10 to 18 and are
a reproduction of a standard form used in the ready-to-wear
trade. The forms can be made in any proportions, and to
get the half and quarter sizes, all the user has to do is put
a little more air into the standard size form. Aside from the
fact that it looks better and is easier to use than conventional
forms, the vinyl type is cheaper, lighter in weight, and port-
able. Conventional dress forms weigh anywhere from 75 to

Effect Of The Marshall Plan On Plastics

The plastics Industry will face some serious problems If the Marshall plan goes through, and
wise Judgment will need to be exercised to avoid adverse effects.

own house In order before we start giving things away, or how we can best feed and house our peo-

-
a'Jready ^^^^iS^"^ *" *** " disintegrating as It has

Since we are hell-bent to go Into this European Recovery program, we are compelled to guard

against Its Inevitable repercussions. Probable enactment of the plan will effect not only the

ilastlcs industry, but all those other Industries that use plastics. In short, the effects of the

be such that plastics users and merchandisers should study at once the possible results

r products and markets caused by the diminishing supplies that will develop as goods sorely

needed over here are shipped abroad.

On business In general, the effects of the plan will not be beneficial In the long run. It
Impossible to ship abroad a sizable portion of the national production without causing serious
nomlc dlslodgments at home. Because these shipments will be financed with American dollars,
icreased Inflationary pressures will be felt here, at a time when less production Is available
for domestic consumption. Besides reducing the efforts that can be devoted to national defense,
these conditions will Involve re Imposition of some war-time controls on Industry, with all that
this Implies In Increased difficulties of doing business efficiently.

Direct shipments abroad will cons 1st largely of machinery, transportation equipment, fuel and
Jd. Molded and fabricated plastics products as such are not likely to be part of the program.
There may well be shipments, though, of unfabrlcated plastics raw materials to assist European
ilastlcs converting Industries to return to a more nearly normal level of operation. In that case
the total supplies available In this country for our own fabricators and molders may be seriously
lessened and stlffer competition encountered In export markets.

Of greater Importance Is a probable return of some degree of control on certain types of
steel, with Its use restricted In certain applications. It Is likely, too, that such restric-
tions would apply first to those uses where suitable replacements are available, such as house-
hold appliances, closures, toys, houseware, hardware and articles of personal use.

These happen to be the fields In which plastics have already been proved and In which they
are presently competing with metals. It has already been reported that manufacturers In some
fields have their engineering departments at work on designs which Incorporate plastics In parts
now using metals that are likely to come under government control.

The Industry must consider the possibility that It will be called upon to fill at least part
of the gap left by withdrawal of steel from the above-mentioned markets. The Industry must also
bear In mind the lessons presumably learned during previous periods of metal shortages.

It must be prepared to maintain the Integrity and quality of the product It produces to meet
what may be greatly Increased demands. In no sense can It expect a return to the war-time exper-
iences and those of the Immediate post-war period when almost anything could be sold. There will
still be competition from aluminum and from other non-ferrous materials, and our competitors will
be quick to capitalize on any errors that we make. Since we will not have the field to ourselves
we must maintain the high standards for which we have strlved.

An Important phase of the Marshall Plan Is to supply Europe with large tonnages of synthetic
fertilizers. This would have a direct effect on the supply of amlno plastics urea and melamlne
formaldehydes and would tend to restrict the supply of formaldehyde, essential In phenollcs and
other thermosettlng materials. It. Is not expected, on the other hand, that allocation or pri-
orities on plastics materials themselves will be found necessary.

In any event, whether we agree with the premises of the Marshall Plan or not, If It Is passed
by the Congress the nation can rely on the plastics Industry to do Its part In keeping the domes-
tic economy on a level keel. END

New design applicable to every type
of handle makes successful marketing
test in luggage sold by the Affiliated
Retailers stores throughout country.
Object of the handle grip is to provide
full use tor all fingers of the hand
with minimum strain. Plastics are
specified because only precision mold
assures accurate reproduction of grip

In the wedge-lock handle, all lingers have a place,
the thumb above all being relieved of the tension and
no-place-to-go feeling; fits both hands comfortably

Molding a. Universal Handle

FUNDAMENTAL anatomical studies of the hand at
work have led to the creation of a plastics handle with
a universal grip which is already being used on a variety of
well-known merchandise and which seems likely to influence
almost every type of handle on the market. If its present
rate of acceptance continues, this innovation will greatly
expand the outlet for plastics materials in handle applica-
tions. For its whole value depends on the exact reproduc-
tion of the grip, and Thomas Lamb, New York, inventor
and industrial designer, who controls the licensing of the
handle, believes that only a plastics precision mold will do
the job. Therefore, except in the relatively small number of
applications where a metal handle might be required, in
which case a precision casting would be authorized, he has
made plastics a "must" material for this new-type of handle.

Market Tests Successful

By-passing for the moment an explanation of their con-
struction, let us consider how the new plastics handles have
fared in the market-place the ultimate proving ground of
any product. Perhaps the first major test was made by
Affiliated Retailers, Inc., the great merchandising chain
composed of 28 stores throughout the country. This group
had polystyrene handles attached to their brand line of
Arflite luggage, which sells at $22.50 and up. Two colors
were used filjauCtan brown and SfiZ^ef^vyfait^ though
samples had been made up in many colors and even mottles.
According to A. N. Ransford, Division Manager, House-
wares, who has charge of the chain's luggage, individual
store buyers offered marked resistance to plastics handles
as such, due to their unpleasant experience with poorly made
varieties in previous years. But they were all "sold" on

the grip; this particular plastics handle looked solid and
sturdy, and was guaranteed for the life of the luggage ; and
anyway they couldn't help themselves they couldn't buy an
abstract grip; they had to take it as it was embodied in
polystyrene or not have it at all.

The store buyers' resistance didn't last long, because cus-
tomers showed no resistance. Introduced in June, the new-
handled luggage had definitely "arrived" within four|
months, so that Lawrence Wood, president of AR, could say
by then that it had "gained 100 per cent acceptance by allj
stores in the group and that sales volume varied from good
to outstanding."

After the initial success with Arflite luggage, Mr. Wood
informs us, the AR group is planning to use the Lamb han-
dles on their brand leather goods, to be followed by portable
radios, Top of Stove Ware, coffee makers, hair brushesj
lunch boxes, record cabinets, vanity cases and animal carry-'
ing cases all products which will be available by Spring of)
this year.

The AR luggage handles are molded by Auburn Button
Works, Auburn, New York, for Standard Handle Co.,
which is licensed to merchandise the free-swinging type of
handle. Auburn itself is also authorized to develop markets
in the many other types of handles.

The molding of the luggage handles is carried out in 2-
cavity molds on a Reed-Prentice machine, and Auburn is*
already improving the original product by using brass in--
serts in the handle holes. By distributing the stress at these'
points along the handle, the grommets are estimated to in-
crease its tensile strength by 40 per cent. Another johy
Auburn is doing for Affiliated Retailers is on skillet handles.'

However, the molds which are being built to produce
them will also be used for a staple line of phenolic handles
and, to widen the color range, of ureas as well. Besides the
standard size handles, Mr. Cohan is projecting a series of
smaller handles for such lighter objects as lunch boxes and
other portable items. In these, the grip remains exactly the
same as in the larger handles, the modification being made
only for appearance sake. These are also to be plungi-r
molded by Auburn Button Works.

Another development Mr. Cohan has under way has
interesting merchandising possibilities. By cutting slots on
both sides of the handle, it will be adapted to carrying
parcels, competing with the familiar wooden handle with
metal loops. This independent handle is intended to be a
chain store item, to sell for about 39#. Along the same line
is a contemplated service for replacing the conventional
handles on luggage and other items which would have the
Lamb design.

What's

Molded wall tiles represent largest
post-war use of plastics in building
construction. Technical problems that
hampered early development have
been overcome, but manufacturers
and distributors have yet to overcome
prejudices of the building trades.
To assure full exploitation of the
market, a forceful educational and
merchandising job needs to be done.
As in other industries now adopting
plastics, a direct comparison with
older materials leads to erroneous
conclusion as to place of product

Most new homes, except those in a very low price bracket, have tiled
kitchens. New polystyrene tile has found wide use in this application

ONE OF THE LARGEST markets open to plastics is
the home building field. It is estimated by the mag-
azine Architectural Record that expenditures for construc-
tion in the 37 eastern states will run at a volume of 8.35
billion dollars during this year, of which 3.27 billion will go
into residential structures.

Plastics are not something new in building, but several
new applications developed since the war have greatly in-
creased the potential volume that will find its way into this
market. Decorative laminates have been in use, particularly
in commercial structures, for about IS years, and their use
continues to grow. Lighting fixtures employing urea and
acrylics, and more lately melamine and polystyrene, are find-
ing increased acceptance. In one room or another, virtually
all commercial plastics are used to some extent in the field.

Plastics in Wall Tile and Floor Coverings

Two of the most important new uses are wall tile and floor
coverings. Floor coverings based on vinyl resins are ap-
proaching commercial production by several different com-
panies, and will shortly be widely available throughout the
country. Initial installations have justified wide usage by
indicating several basic advantages over conventional older
materials.

The first new post-war product to get into volume pro-
duction is molded polystyrene wall tile. It is reported that
more than 40 companies are presently turning it out. These
tiles are essentially flat 4" X 4" pieces provided with a bev-
eled edge, and molded with a glossy surface resembling that

of glazed ceramic tile. One company has modified the de-
sign to provide for concealed projections interlocking one
tile to the next, although other companies find this feature
unnecessary. Polystyrene wall tiles have been in use for
over a year, and it is possible now to report on the success
with which this new plastics application has met in home
building.

A check of factors in the building field in Chicago and in
New York indicates clearly that a great deal more educa-
tional and promotional effort must be put forth before 100
per cent acceptance of the new product is assured. In both
centers, there are a number of tile contractors and tile dis-
tributors who have either never heard or never seen samples
of the molded tile, or who have picked up an adverse opinion
about it based on inadequate information. On the other
hand, those contractors and distributors who have sold or
used the tile, in general report highly favorably on it. There
is growing, though, a misinformed attitude, which must be
corrected if this phase of the industry is to be built on a
sound basis. Such a corrective program can be put into
effect and can be successful, as shown by experience with
those people in the tile business who have been well-edu-
cated in the characteristics and properties of the new prod-
uct. It is not possible merely to offer the new tile through
regular trade channels and expect it to be accepted on its
face value alone.

In Chicago, for instance, one of the largest distributors of
polystyrene tile has set up an educational program for deal-
ers and contractors, consisting of several lectures which give

Happening in Wall Tile

Polystyrene tile bathroom walls capably withstand the ex-
posure to hot, humid atmospheres to which they are submitted

these people the essential facts about wall tiles, so as to
enable an intelligent job to be done in selling and in in-
stalling them.

In studying the problem, it is necessary that the new
naterial be considered against the background of older con-
ventional products for hard-surface wall coverings. Use of
he injection molded tile has been most prominent to date
n the bathrooms and kitchens of private homes and apart-
nents. The purpose of such a hard, permanent wall cover-
ng is to provide a durable, washable surface that looks and
s clean and attractive. Although hospitals, eating places
md industrial buildings are also big users of tile, the quick-
st acceptance for plastics tile has been in the home. Here,
>articularly in bathrooms, tile walls have become almost a
must" for modern styling. Virtually all new homes, ex-
ept those in the very lowest price bracket, have partially
iled bathrooms, and many have tiled kitchens. In both bath-
ooms and kitchens, the walls are frequently exposed to hot,
lumid atmospheres, and obviously must withstand such ex-
>osure. In bathrooms, tile walls are also subject to direct
treams of hot water.

Glazed ceramic tile is the oldest and probably the most
videly accepted material for such application. It has been
n use since earliest antiquity, and its advantages and dis-
advantages are well known and accepted. It presents, when
aid up with mastic, a hard surface that is substantially
ivaterproof and which retains its gloss over a period of
fears. It does have a tendency to crack in time, and some
maintenance is required after it has been in use about 10
/ears. Some types also show a tendency to absorb dirt and
:o discolor. The mortar which fills the spaces is also some-
.vhat absorbent of dirt and soil and eventually discolors.

In developing molded polystyrene tile, manufacturers have
een fit to attempt a duplication of the appearance of ceram-
cs. This is natural, but not necessarily the soundest policy

Reproduced in these pages are some typical advertise-
ments of such merchandise, although they do not include all
that appeared in one Sunday's papers.

Several things stand out from an examination of these
ads. One is that plastics are seldom identified by type, al-
though trade names do occur with a reasonable amount of
frequency.

Apparently, department store advertising copywriters use
the generic term plastics when they do not have a manufac-
turer's trade name to use. Presumably, the stores either do
not know the different types of plastics or they feel that the
use of such terms would mean little to consumers, whereas
trade names are felt to have some identification value. It
is noteworthy too that trade names of plastics materials
are sometimes used even when they are not recognized as
such.

Although many stores will feature a product which has a
plastics' housing, they do not always draw attention to this
particular point.

An example is the ad for the Emerson radio seen in the
upper right hand corner of the accompanying illustration.
No mention is made in the ad that the cabinet is molded of
urea. The characteristic design used in this particular
model, however, would be economically available only in a
molded case.

In some of the newspapers, advertisements of manu-
facturers or distributors appealing directly to consumers
are seen from time to time, although the great bulk of space
is utilized by department stores. END

Promotion Must Be Many-Sided

TO MANY PEOPLE in the conversion end of the
plastics industry, the whole answer to its present prob-
lems is : Put more salesmen on the road. Such a solution
is apt to be looked on as a cure-all, especially by such proc-
essors who have not had much of a sales organization before,
since it is obvious that the sales force is the fulcrum of new
business. The men on the road are the ones who sign up
new customers as well as renew contacts with the old.

Yet this solution is strenuously opposed by Todd Harris,
Creative Plastics Corp., Brooklyn, New York. Despite
the fact that he is an energetic salesman himself, Mr. Harris
is of the opinion that only a well-balanced promotion cam-
paign can build up sales. This may call for more salesmen,
but it also requires a long-range advertising program and
persistent, quality publicity.

On the first score the enlarging of the sales staff Mr.
Harris points out that two major factors are to be con-
sidered. In the first place there are economic limitations.
An added salesman, with his commission of five or more
per cent, may consume much of the competitive operating
margin of a company, especially on the larger jobs which
are the backbone of a production schedule.

If its price formula is based on 1946 volume and that vol-
ume has declined, the salesman's commission will represent a
loss. To guard against this, the salesman must be put on a
quota basis and the price formula must be carefully re-
checked.

If a company is well-established and enjoys a solid follow-
ing, it may, at great risk, take advantage of its prestige to
pass on the salesman's commission to the customer. There
is the additional deterrent of the strongly competitive cur-
rent market to dissuade even these well-established firms
from assuming such a position. Every new salesman should
therefore be taken on as a calculated risk.

Type of Salesman Important

Mr. Harris's second caution refers to the quality of new
salesmen. There is no question but that "any salesman"
will not do. But between "any" salesman and a well-
qualified one, there is a wide range of so-so, "nice guy,"
pretty good and almost right. None of these is worth while ;
allowing for differences of personality, the only good sales-
man in this critical transition period of the plastics con-
verter is the man who understands the product or service
he represents. By "understanding," Mr. Harris doesn't
mean that a salesman must merely know the difference, say,
between molding and fabricating, or even that he should
know "in a general way" what molding or fabricating is
whichever type of firm he works for. Mr. Harris's defini-
tion of a good salesman is a man who knows what to do
with specific inquiries when he gets them.

The source of the inquiry may be an end-user who has
been persuaded by the company's ad, or it may be a lead the
salesman himself has turned up in his territory. To convert
the inquiry into business, he must know enough about plas-
tics materials and processing to give, on the spot, a sensible
if tentative answer to the inquirer's problem. If the latter
calls for a molding job, and the salesman represents a fabri-
cator, he should politely bow out of the picture and recom-
mend a reliable molder or two. If, however, there is a
potential fabricating contract to be signed, the salesman
must know enough to suggest which of the many plastics
is likely to give the right performance and to estimate the
approximate tooling cost and price of the desired product.

To give a salesman the right background of knowledge,
a company must put him "through the works" in its own

A fabricator takes issue with the commonly
expressed idea that off that is necessary
to improve a business is fo increase the
sales staff. Consistent advertising and
publicity, the right kind of a selling
staff, intensive following up of leads and
creative design service, are ail essential
components of a well-rounded promotion
campaign to build up a successful business

plant, supplementing this practical training, if necessary,
with courses at educational institutions and study of the
industry's literature and publications.

As Mr. Harris says, anybody can refer an inquiry back to
the home office, and it is a common complaint of customers
that too many salesmen do not have the knowledge to answer
questions on the spot, or the authority to back up their sug-
gestions.

When a new salesman has not yet proved himself, Mr.
Harris suggests that a principal of the firm call on a poten-
tial client when a substantial deal is in the making. Too
many sales managers, he feels, are still "sitting it out."

Just as some inexperienced converters put their faith in
"more men on the road," others, Mr. Harris finds, have too
facile a belief in the power of advertising. Some firms permit
their situation to become desperate, before they hurriedly
begin to advertise, hoping to be saved by an immediate sales
response. Other firms, which may not have run an ad in
years, think that all they have to do is spend a few hundred
dollars on one good ad in 1948 and business will roll in.
That, Mr. Harris believes, is an easy way of throwing
money away; only the right kind of advertising pays off.
And the right kind of advertising is steady advertising not
merely month after month, but a campaign conceived as a
whole, so that each ad reinforces the message of the ones
preceding and paves the way for those to come.

Utilizing Ad Value

The value of an ad need not end with its publication in a
trade magazine or other medium. At Creative Plastics, for
example, reprints of ads are used in direct mail promotion.
Multigraph letters, in Mr. Harris's experience, are flops,
but he has found that individual letters, with reprints en-
closed on a subject which is of direct interest to the ad-
dressee, pay off handsomely. Of these, one out of 10 brings
an answer, and since the letters are not broadcast on the
wind, "to whoever it may concern," but are sent only to
good potential prospects, the results have been gratifying.

Another form of promotion used by Creative Plastics is
more expensive and therefore is resorted to with an even
more select list of prospects. To them are sent actual
samples of products made, together with a "Creative Quiz,"
on the answers to which the firm can decide whether to |
recommend the use of plastics in the prospect's own product.

No people is more publicity-minded than the American
people, yet the plastics industry, according to Mr. Harris,

TAese Place Mats are Permanent

A place mat with a circus design, which the
children's restaurant of McCreery's once
used on a metaf tray, is now laminated into
distinctive tabie tops. This gives greater
convenience and beauty, saves cost of paper
place mats and sanitation of metal trays.
Application suggests permanent reproduction
of wine cards, menus, crests and other such
devices, where large-quantity production is
not feasible. Initial installation cost at
McCreery's will pay off in matter of months

Place mats with circus handbills are permanently laminated
into the table's top at children's restaurant at McCreery's

THE FEASIBILITY of ordering laminate table tops of
special design in limited quantities is demonstrated in
a new installation in the "Big Top" restaurant of James
McCreery & Co., New York specialty store. This develop-
ment should also be of interest as a potential application of
the same type of surfacing plastics to obtain permanent re-
productions of menus, wine lists, coats-of-arms and other
devices for use in the home, restaurants and other public
places.

The "Big Top" is designed, as its name indicates, to give
the air of a circus. A tent entrance, murals with animal
motives and old-time circus posters provide the setting in
which youngsters have their lunch at McCreery's 40 per
cent of the restaurant's patrons are under 10 years of age,
and in holiday seasons, to reverse the usual movie regula-
tions, no adult is admitted unless he is accompanied by a
child.

Atmospheric for Children

To bring the circus atmosphere right into the laps of the
kids, so to speak, the restaurant used to supply metal trays
with 11"X14" paper place mats on which old circus hand-
bills were reproduced.

Naturally, place mats of this type were able to be disposed
of like paper napkins, and they cost the store from four to
five thousand dollars a year. In order to keep the trays
themselves in a sanitary condition, and to keep them neat in
appearance, much time and labor was consumed.

The manager of the store's three restaurants took up his
problem with Paul S. Jones Company, suppliers of restau-
rant equipment, and this firm in turn discussed it with
Formica Insulation Company, which came up with the solu-
tion.

Lithographic plates were made from the original circus
handbills, and the prints were run off on a paper which

could be impregnated with melamine resin (Melmac, in this
case) and used as the top sheet of the layup of which high
pressure laminates are made. (Actually, one, two or four
facsimiles of the place mats are used, depending on the size
of the table top.)

Many Advantages

In this way the circus handbill, reproduced with the
greatest clarity, becomes an integral part of the table top,
which is hard, chip-resistant and stands up under severe
usage without scratching or marring. It is chemically inert,
so that it does not impart taste or odor to food resting on it ;
it does not stain or discolor; and it may be cleaned with a
damp cloth. No polishing or waxing is required to maintain
the glossy surface.

The store no longer has to bother about removing the
trays, rendering them sanitary, and disposing of the place
mats; and the new table top is far more attractive than the
old one.

Its initial cost is made up in a matter of months, and the
improved service which is rendered by the handsome tables
keeps on paying off.

Strong in Promotion

It is worthy of note that the McCreery installation in-
cludes table tops of irregular shape as well as those which
are square.

While most of them are designed for two persons, there
are some on which one person and others on which four are
served. The tops of all the tables have a buff linen pattern.

Indicative of the strong promotion trend in the industry,
the new Formica installation at McCreery's was made the
occasion of a press preview. This celebration was held un-
der the auspices of the American Cyanamid Company's
Plastics Division. END

Plastics where plastics belong . . . for insulation and appearance

The uses for Synthane laminated plastics are almost unlimited
because of their combination of chemical, electrical and mechan-
ical properties. Moisture and corrosion resistance, light weight,
and ease of machining are only a few of the characteristics
that qualify Synthane for so many practical applications.
Synthane is also hard, dense, strong, one of the best electrical
insulators known. It is the "set" plastic, stable over a wide
range of temperatures.

An interesting example of Synthane at work is this jack
panel used by RCA to control your favorite radio program. .

Photograph Courtesy ol Station WNf W, N.Y.C.

In the control console (above) the jack panel enables the
broadcast technician to plug in or transfer amplifiers, micro-
phones, telephone lines or other equipment, giving the input
system greater operating flexibility. This is an appropriate job
for our type of plastics because Synthane is an excellent elec-
trical insulator, and contributes to. the attractiveness of the
control booth.

Perhaps one of Synthane's many properties suggests a use
for it in your plant. If so, let us help you with design, ma-
terials or completely fabricated parts. Write for our complete

JUKE BOXES COMMONLY obey the exhortation <.i
Billy Sunday's favorite tune "Brighten the corner
where you are" and plastics have contributed heavily to
their ga^ and, let's confess.it, sometimes gaudy colors. There
is more restraint in the new Model 1100 produced by the
Rudolph Wurlitzer Company, North Tonawanda, N. Y., in
which clear acrylics have been used effectively along with
many other types of plastics.

For the first time a juke box uses a plastics material for
a complete record changer compartment window. This
Plexiglas bubble and the rest of the instrument's plastics
dress are what strike the eye, though it is the new technical
features which make the company publicize it as the "first
real post-war commetcial phonograph."

Set in the front door framework, the acrylic window is
approximately 30" wide at the base and 18" high, forming
the entire top section of the phonograph's front door.
Through it, the juke box customer can view the fascinating
record-changing operation which his nickel sets in motion.
Up to now, glass has been the customary material for this
part, and has imposed restrictions on its shape. With acrylic
windows, easily formed, this limitation is lifted and a
greater flexibility of design is possible.

A more restrained, though still colorful

model which features clear acrylic window
and grilles. Acetate cylinders rotating
behind fluted styrene surfaces create
bizarre color patterns. There are many
other plastics used in this instrument.
Wurlitzer does its own fabrication, but
finds it more economical to have several
of the parts in/ecfion molded elsewhere

plastics for corner pilasters and grille sections. Subject to
constant heat from interior illumination and unprotected
from sunlight and other external hazards, these parts of
colored or painted plastics are liable to fade or become dis-
colored and require replacement. To eliminate this mainte-
nance problem without sacrificing brilliant color illumina-
tion, Wurlitzer has designed a novel lighting arrangement
in combination with metal and plastics.

The curved corner pilasters are being made of clear,
transparent polystyrene spirally fluted on one surface and
vertically fluted on the other. The intersection of these
opposing flutes creates the effect of hundreds of small, some-
what rectangular lenses. The same clear, fluted material
is used for the S-shaped grille plastics which flank the
speaker grille. The two sheets of perforated Rigidized
Metal which form the V-shaped speaker grille constitute
a radical change from the grille cloth which normally covers
juke box speakers.

Color Patterns

Two moving color cylinders, one at either side of the
door, revolve behind the fluted pilasters and grille. These
color cylinders consist of vertical bands of red, amber,
green and blue cellulose acetate bonded together and en-
close standard fluorescent tube lights. Behind the front
door proper is a hinged half -door or panel which supports
the speaker and coin mechanism. This speaker door pre-
vents the escape of any light from the color cylinders into
the interior of the phonograph. In addition, the front of this
speaker door and all other exposed surfaces surrounding
the color cylinders are sheathed with Rigidized Metal, which
diffuses and reflects the trapped light forward. This full
utilization of light from the color cylinders creates a bril-
liant illumination which is not even dimmed by daylight.

By virtue of the optical distortion created by the curved
and fluted styrene, the slowly turning color cylinders weave
a bizarre tapestry of light with an ever-changing pattern.
The color that spills through the grille plastics is diffused
and reflected again by the bright Rigidized Metal speaker
grille. At the bottom of the door is a decorative polished
grille casting backed by translucent, red cellulose acetate.
Illuminated by two incandescent bulbs, this trim adds the
final touch of color.

An entirely new record selector unit, which Wurlitzer

calls the "Encore Program Selector," makes its debut on
Model 1100. Its three-sided program holder carries eight
title strips to a side, but only one side is visible at a time.
Number rollers above the selector keys show eight numbers
at a time corresponding to the titles which are visible. When
a master key is pressed, the program holder and number
rollers rotate, bringing to view a new set of eight titles and
numbers. Simultaneously, switches within the unit change
their contacts, so that the eight selector key.s suffice to
make 24 different selections. By thus dividing the phono-
graph's 24 records into three programs of eight selections
each, record selection is made easier, faster and more fun for
the juke box customer^

Plastics are liberally used in the construction of this
selector unit. The three sides of the program holder are of
compression-molded phenolics. Title slips are held in place
on the program holder by red retainer strips of Tenite II
(acetate butyrate). The polystyrene number rollers, lighted
from within by tiny incandescent bulbs, revolve behind
protecting windows of clear acrylic. The rollers are in-
jection-molded in three sections, and each section is painted
a different color on its inside surface. Roller numbers are
indented on the inside surface in the molding and later filled
with black paint.

The alternate red and white selector keys are injection-
molded of opaque cellulose acetate butyrate. The master
key, of the same material, illustrates an interesting double
injection molding process. This red key carries lettering
which reads "Press to change program." Painted letters
would not stand up under the constant hard use to which
this key is subjected. Therefore, the red section of the key
is first molded leaving the letters hollow. A second injec-
tion molding of white cellulose acetate fills the hollows,
creating letters as deep and as indestructible as the key itself.
Quinn-Berry Corporation, Erie, Pa., has developed this
process for Wurlitzer and is molding the keys.

Selector Keys Injection-Molded

The coin-return button and the plastics numeral insert,
on either side of the program selector, are injection-molded
in the same fashion as the master program change key.
Over the coin entry is a panel which bears the legend "5-10-
25 cents." This panel is made up of two plastics strips. One

The replacement of a wooden base by
a clear acrylic, and of a rubber die by
polyvinyi acetate, makes possible new
map-marking device which allows the
user to see just where he is placing
symbol. The all-visible marker offers
many other application possibilities

Better Than a Rubber Stamp

THE TRADITIONAL rubber stamp has been divested
of its rubber and of its wood in a map-marking
stamp made entirely of plastics materials by Acromark Com-
pany, Elizabeth, New Jersey. The new marker was con-
ceived by the company's owner, H. O. Bates, when one of
his customers complained that he had never been able to
spot his sales maps properly with a rubber stamp.

Where a map is marked permanently rather than by a
movable pin, tack or flag, a- rubber stamp bearing the re-
quired symbol is customarily employed. Being opaque, its
chief disadvantage is that the user cannot see the spot loca-
tion at which he wishes to set the mark. The Bates map

v marker achieves complete visibility by means of four ele-
ments of its design : ( 1 ) The base block, conventionally of
wood, is made of clear acrylic. (2) The die bearing the sym-

bol is moved off-center so as not to be in a direct line with
the axis of the handle. (3) The die, instead of being made
of opaque rubber, is molded of translucent polyvinyl acetate.
When stamping ink is applied to the marking symbol, the
latter itself becomes visible through the PVA. (4) Precise-
spot visibility the most strategic element of the design
is obtained by a sighting aperture punched through the
island recess in the middle of the symbol. With the PVA
die bonded to the nether side of the "Plexiglas" base block,

the spot on the map intended for marking can be clearly
sighted through both acrylic and aperture.

The principle of visibility in such a marking stamp has
considerable implications both in map-marking specifically
and in "rubber-stamping" generally. For one thing, by the
adoption of color for the transparent base block, differenti-
ation as between office and office or function and function
can be obtained without affecting visibility through the
stamp. For another, corollary or subsidiary markings that
modify a basic symbol can be easily executed. This is
of especial importance for both sales and industrial map-
marking.

Greater Potentialities

The design theory of the marker was extended, its func-
tion made more flexible and its potentialities amplified when
the sighting aperture was taken out of the confines of the
center of the symbol and placed wherever any given function
would require at the center, edge, corner or side of the
symbol.

A typical example of the functioning of the new marker
is its use by a large manufacturer to spot his map to indi-
cate various offices and stations (Fig. 1).

All of these indications are based upon only two plastics

the basic element, modifications at any givep map location
can be made at any time that the functions of a district office
are enlarged.- This is something that is almost impossible
to accomplish with any reasonable accuracy with the con-
ventional rubber stamp.

The design flexibility of the marker and the extension of
its functions may be exemplified in the manufacturer's

For this purpose, the dies shown in Fig. 3 are needed.

That the map marker will function for enterprises other
than those involving offices or branches may be shown in
such an activity as surveying the crossing facilities on a
100-mile stream. Fig. 6 would show this.

The dies in Fig. 7 would be needed for this purpose.

The potentialities of the new marking stamp go consid-
erably beyond its use in map-marking and reach well into
the field of stamping generally. This holds especially where
accuracy of mark positioning is desirable, whether for quick
reading or for neatness of appearance. An obvious example
is a department store merchandise tag. In apparel, for in-
stance, the tag is marked on succeeding lines for lot num-
ber, size and price. With the conventional rubber stamp,
unless time-consuming care is taken, the markings are often
askew. Straight, accurately positioned marks are easily
and quickly executed with the all-plastics marking stamp.

An imaginative but practical industrial designer considers the role of plastics in an ideal
iron. A plastics shell is wholly feasible, from the angles of both function and style. Shell
could be molded in one piece with the handle, but two components are preferable. Hand
grip factors are analyzed in detail, and the possibilities for two-color use are pointed out

ll/lartin terown&nietd

Industrial Designer, Elm Laboratories

PLASTICS HAVE BEEN used in the manufacture of electric
flatirons for some time, but the application has been
limited to handles and thermal control knobs. Many manu-
facturers, especially during periods of materials scarcity,
were prevented from using even this amount of plastics
on their products. The adaptability of plastics material for
iron handles is now accepted without question, as years of
use have proved its practical and durable qualities for this
specific application. Though phenolic materials are now
available, a number of irons, where low price and not utility
is the prime consideration, still limp along with obsolete
wooden handles. The further application of plastics can
enable designers to advance the development of flatirons so
that some of the major problems that trouble manufacturers
today will be overcome.

The plastics molder is confronted mainly with produc-
tion details in supplying finished parts of a fixed design.
His advice to the manufacturer is confined to suggestions
and design changes to facilitate the process of molding, such
as ribbing, fillets and bosses. With an understanding of the
operating characteristics of electric iron components, recom-
mendations can be made for improved construction.

Our organization recently completed a series of survey
tests of most available flatirons for consumer research pur-
poses. Irons were tested for electrical performance and dis-
sected for mechanical construction. The conclusions based
upon this laboratory data indicate that a more ingenious
use of plastics can be as important in the improvement of
flatiron construction as was the addition of thermal con-
trols to non-automatic irons.

The major advantages that can be obtained through the
use of plastics are grouped into two classes: utility and
styling. The utility features are : protection against radiant
heat from the metal shell; shaping the handle for sliding,
not lifting; simplifying the problem of lightweight construc-
tion ; positioning thermal controls that are cool to the touch
and easy to read.

The styling features are: balanced design for stability;
comfortable handles twinned for right- and left-handed use;
simple manufacturing assembly; ease in repairing; ease in
cleaning.

Protection from Heat

Plastics can be used for protecting the hand from heat
radiated from the highly polished plated metal shells. The
intensity of the heat increases with the advanced settings of
the thermostat, so that when the iron is operated at the
normal "high," the sole plate temperature averages about
530 F. Since the shell is a hood over the sole plate and j
element, it is heated by direct conduction from the sole plate,
and also by radiation heating of the air chamber by thej
element.

The temperatures are not uniform over the entire shell
area, since the proximity of the heating element varies with
the shape of the shell. At the tip of the iron where there
is a concentration of heat, the shell temperatures average
286 F, while at the tail the average temperature is still as
high as 249 F. At the middle of the iron, where the
knuckles are closest to the heated shell, the clearance space
only averages a scant inch and a quarter, and the average \
temperature at this point of the samples tested was 275 F. ,
This is too hot for comfort, and the hazard of contact burns
is constantly present.

A properly shaped plastics shell with an under-shell heat
shield mounted over the element and sole plate is the solu-

PLASTiCS

JANUARY 1948

ion to the radiant heat problem. Cast aluminum should
used for the heat baffle, and it must be treated for de-
lection of heat back to the sole plate. An ideal design for

plastics shell should contain a deep cup which amply ac-
ommodates the gripped fingers. The heat along the outer
dges of the sole plate is deflected from the user's hand,
/hich is protected in the hilt-like guard of the concave shell.

Following through on the design of the shell, the handle
hould be angled for facile sliding, since the heat of the sole
late, and not the weight of the iron, does the work. Han-
les shaped for lifting, not sliding, are carryovers from the
bsolete sadirons, which were not self-heated. As these
rons cooled with use, they were lifted and pounded to
tilize the last remaining bit of heat, before replacing them
n the coal stove or kitchen range, the usual source of
eat supply. With the uniform heat of automatic irons,
tundry work is facilitated with the sliding, not slamming,
:chnique. "Lift" handles distort the grip and cause muscu-
r strain at the wrist, and as it is no more complicated to
lold "slide" handles, emphasis should be placed upon the
orrect angling of the hand bar.

rinding Corrected Misfits

Of the molded handles now being used on irons, we found
lat, although the proper material was chosen, many of the
olds were either poorly made or had dimensional errors.
Mere the molds were not properly matched, high parting
nes were produced, and this ridge of useless material often
at into the hand of the user. Misfits at the mounting point
metal components and molding were corrected by grind-
g the latter, resulting in chipping and loss of luster. The
ual method of assembly, by milled rod or hook and slot
rangement, has been found satisfactory for mass produc-
Dn methods.

The overall weight of the flatiron can be considerably
duced with the use of the plastics shell, in combination
ith the plastics handle. There is considerable saving in
eight, as mounting brackets, reinforcement strips, and ter-
nal bars are not required in the use of a plastics shell,
hese parts are replaced by slots and bosses molded into
e underside of the shell. The substitution of the weighty
etal parts by molded details incorporated in the plastics
ell allows a concentration of weight in the sole plate. This
akes it possible to increase the thickness of the sole plate,
:ontrolling factor in uniform heat distribution.
Plastics thermostat knobs, even those combined with
irts which are embossed as dials, become excessively hot
len placed in the middle of the shell. In this location
der the handle, the reading of the dial and the adjust-
;nt of settings are obstructed. With a molded plastics
ell and handle, it is easier to locate the thermal controls
ay from heat mass centers. Mounting the control knob
the front end of the handle where it will remain cool
ices it in an -unobstructed line of vision. In this position,
: temperature settings can be conveniently adjusted with
5 fingertips while the user's hand continues to remain on
: handle.

yling Is of Vital Importance

The styljm'g of the iron, as in any, other appliance, is of
al importance in sales appeal. However, careful construc-
n which eliminates breakdowns and subsequent return of
ective and inefficient units, is the foundation of good

igning. A stylist can use plastics to advantage in design-
' a flatiron, but he must know the 'exact functions and
hnical characteristics of each component. A large thermal
itrol knob, normally easy to handle, would be a poor
ign if it were located at a point where it conducted ex-
me heat.
Ihe flow of lines of the design should follow through with

functions of the product. A handle shaped for sliding

should blend with the lines of the shell to which it is at-
tached, and it should be physically balanced for stability.
Here again, plastics molded in equal halves assures perfect
balance of the major portion of the iron. The smooth sur-
faces of molded plastics produce effective streamlining and
eliminate projections and openings which catch threads and
collect dust.

The shape of the handle should accommodate the contour
of the hand for a comfortable grip. The portion of the
handle upon which the palm rests should form a deep saddle.
Continuation of this rear portion of the handle will form
one point of the idling stand. Extending the comfortable
grip to the front end, a thumb rest is an advantage, and
since the handle should be twinned for left- and right-hand
use, physical balance is maintained in the molding of iden-
tical halves.

In the initial design of the mold for the plastics shell,
bosses, slots and grooves can be incorporated. These mold-
ing details eliminate sub-assemblies, replacing many sep-
arate pieces. The sole plate with embedded element and
thermostat is assembled in the conventional manner. How-
ever, the plastics shell and handle are a simplified sub-
assembly, involving fewer parts and operations, and result-
ing in considerable labor cost reduction.

The shell and handle may be of one piece, although a more
practical method is to mold two separate pieces. The
thermal control knob is fitted into the handle in the first
sub-assembly, in which the handle is attached to the shell.
This sub-assembly is carried in an inverted position along
the assembly line. Thermal control mechanisms are dropped
into cavities of the molded shell. Line cord is fitted through
a shell opening and connected at terminal studs, which are
part of the molded shell. After sliding the shell over the sole
plate, a single screw secures the shell and handle to the
sole plate. Threaded metal inserts should be molded into the
plastics parts to receive assembly screws.

Any part may be replaced for repair, or the entire sole
plate assembly with factory adjusted thermostat can easily
be installed in the field by a local repair man.

Heat-Resistant Phenolic for Shell

High heat-resistant phenolic material should be used for
the molded shell. Normally this material is rated to success-
fully withstand temperatures as high as 400 F. Since the
average operating temperature of metal shells of the sam-
ples tested was 286 F, a plastics shell, shielded by the heat
baffle, should have a still lower operating temperature. These
phenolics are usually supplied in black, but since the oper-
ating temperatures of handles vary from 80 F to 120 F
when used with an iron having a metal shell, an iron with a
plastics shell should operate near the minimum of 80 F.
This will permit the use of contrasting colored plastics for
the handle.

Temperature scale should be embossed on the thermal
control knob, so that reading of temperatures is simultane-
ous with the adjustment operation. The embossed valleys
should be deep enough to hold fill-in material of contrasting
color. A number of plastics materials which permit sharp
molded lines, as required for small numerals and lettering,
are available in colors to contrast with the handle and the
shell.

The general trend is towards this type of iron construc-
tion. Several new irons have one or two of the features of
the Ideal Iron discussed in this article. Some iron manufac-
turers are broadening .the base of the handle to cover the
top of the metal shell. Others are using twinned handles
and fingertip thermal controls. There is, however, no iron
available with a complete plastics shell and all the utility
features of the Ideal Iron. But a broader application of the
proper plastics materials is steadily advancing modern flat-
irons in improved appearance and utility. END

"Fosterite"-asbestos laminate is being made in a wide variety
of forms and shapes, from flat sheets to molded curved pieces

New type laminate made of asbestos
impregnated with an alkyd-vinyl
resin successfully replaces mica
as insulation for commutator-bars

C-.

Alky d- Vinyl

ASBESTOS impregnated with an alkyd-vinyl resin
formulation has proved to be an excellent insulating
material for commutator-bars. The resin is one of a series
known as Fosterite resins developed by Westinghouse dur-
ing the war for moisture-proofing and insulating electrical
equipment when it seemed that the sources of supply of
mica would be cut off.

A satisfactory commutator-bar insulation must have sev-
eral different characteristics. Primarily, it must be physi-
cally stable at 100 C in order that the commutator may be
kept tight and smooth. Commutator-bar insulation also
must have good arc resistance, good dielectric strength, be
non-tracking, have a "seasoning set" similar to shellac-
bonded mica insulation, and also be sandable and punch-
able.

As a substitute for shellac-bonded mica, many combina-
tions of synthetic resins with paper or fabrics were made,
examined, and discarded during the development program.
Phenolic laminates were eliminated because they track read-
ily and lack arc resistance. Natural resins were not consid-
ered because they might become unavailable. The material
that proved most satisfactory was a combination of asbestos
paper and a Fosterite resin. The particular formulation
chosen for making commutator insulation has physical char-
acteristics similar to those of shellac-bonded mica.

A finished sheet of Micarta 8564 insulating material,
which, for convenience, I shall hereafter refer to as "Fos-
terite asbestos," is similar in appearance to phenolic-bonded,
asbestos-paper laminate except that its surface is not quite
as glossy. Like other plastics laminates, the material is
monolithic in character, so that, unlike mica, it cannot de-
laminate. It punches readily much better than an asbestos-
paper phenolic laminate, which often has to be punched hot
to prevent craze cracking; it can be sawed, but not as
easily as the conventional type of asbestos-paper laminate,
and saws must be sharpened more often. However, it can

e readily undercut on commutators, although the cutting
rheels have to be replaced oftener than when under-
utting mica-insulated commutators. The material can be
anded and the tolerances held to 0.0005". In this re-
pect, it is considerably better than mica sheets, which can
e held to 0.001" only with considerable difficulty.

Conventional resin-treated paper and Fosterite resin-
eated asbestos differ in finished appearance. A phenolic-
eated paper is merely coated, and the product is quite
tiff. The Fosterite resin solution is water-thin and actually
npregnates the paper instead of coating it. A solution
rhich contains 60% solids has a viscosity of 25 cp, while

50% solids solution of a phenolic resin has a viscosity of
30 cp, indicating its fluidity.

Asbestos paper treated with Fosterite resin looks like
lotting paper and has a leathery feel. The treated paper
mnot be stored for more than three or four days and must
: kept covered because one of the ingredients of the resin

slightly volatile. If the treated paper is stored too long,

will set and become unsuitable for laminated parts.

9 Make in Laminate Form

To make Foster ite-a.sbestos in laminate form, sheets of
ibestos, in the present batch process, are stacked in racks
id lowered into the impregnating solution for approxi-
ately 30 min. The racks are then removed from the im-
egnant and allowed to drain for about one hour. The
ipregnated paper is placed in an oven heated to 60 C
r five minutes to remove the solvent, after which it is
ady for laminating.

The equipment used is the same as for preparing conven-
snal laminated materials. Fosterite-asbestos is placed in a
Id press and the pressure applied before the press is
ated; otherwise, it reacts so quickly to temperature that
e material would set before pressure could be applied,
ic laminating pressures range from 100 to 1500 psi, the
gtier pressures tending to make a better sheet.

Although Fosterite-asbestos was developed for use as a
commutator insulation, it soon became evident that its
physical properties were such that molded products could
be fabricated easily. The treated paper is soft, pliable, and
takes a deep draw.

The process for molding is simple compared to that for
molding mica. To mold mica, thin sheets must be fabricated,
sanded to size, surface coated, cut into blanks, preformed,
and finally molded. To mold Fosterite-asbestos, the paper
is treated with the resin solution, cut into blanks, and then
molded. Many operations are eliminated. The finished prod-
uct is thermally set and does not resoften on heating as
does mica.

What's Happening in Wail Tile

(Continued from page 27)

over a long term. Ceramic tile is made in small squares be-
cause of its low tensile strength. Large pieces tend to break.
There is no good reason why plastics tile should not be made
in larger panels, with resultant economies in handling in-
stallation. Likewise, molded tile manufacturers have mag-
nified their difficulties by presenting their product with the
glazed surface characteristic of ceramics. They might just
as well have used a texture with nothing more than a satin
finish. Polystyrene does not have as hard a surface as
- ceramic glaze, and" in some quarters the impression has
grown that the plastics tiles tend to scratch readily. This
tendency would not be so evident if the surfaces were not
shiny.

Standard practice for installation of clay tile involves the
application of one to two inches of cement mortar over a
scratch plaster base. The use of a thick mortar layer per-
mits the tile setter to compensate for slight irregularities in
the wall or in the tile to assure a plumb and flat finished job.
This practice is made necessary particularly by the irregular
thickness of any baked clay product. With injection molded
tile, however, thickness can be held to close tolerances, mak-
ing a thick mortar base unnecessary. Therefore, a much
thinner layer of mastic adhesive is used instead of cement
mortar, and it provides a high degree of permanence and
adhesion since adhesive manufacturers have made formula-
tions specifically for polystyrene. The mere difference in
this detail has led to resistance from the tile trade, which
has become accustomed over a period of years to working
with cement mortar. Reports of tile falling off after in-
- stallation derive in large part from unfamiliarity with the
technique for installing molded tile.

Wide Color Range Possible

The subject of color represents another area where plas-
tics manufacturers must do a real educational job. Actually,
of course, the range of colors available in polystyrene eco-
nomically exceeds that in ceramics. In ceramics, uniform
colors are more difficult to obtain than with polystyrene
plastics. It is also possible in polystyrene to attain mottles,
which are not feasible with ceramics. The issue is clouded,
however, by the fact that some molders at first had trouble
in avoiding flow marks in their products. To conceal these
marks, mottle molding materials were used. The same dif-
ficulties that caused flow marks were also indicative of poor
molding technique and, as a result, mottled tile has become
associated with poorly molded pieces. It is necessary that
this misapprehension be corrected to permit fuller exploita-
tion of the color range of plastics tile.

It is interesting to note that newer types of hard surfaced
wall coverings have successfully penetrated the market once
held by ceramics. The cheapest of these is "tile board,"
which is painted or enamelled pressed hardboard, and is used
as a low cost substitute for genuine tile. The surface of
this product is scored to resemble individually set tile,
though it is actually sold and installed in large panels. Its
chief drawback is that the base absorbs moisture too easily ;
only the surface coating is moisture resistant. The result
is warping, peeling and cracking after a few years. These
characteristics make tile board a rather poor substitute, but
it has won wide use because of initial low cost.

A more substantial replacement material is steel tile,
which consists of sheet steel scored in squares and painted
or enamelled. This product has much greater durability,
although it does show a tendency to peel after a relatively
short time. There are hotels in various parts of the coun-
try, erected during the late '20's, which have steel tile walls

bare of paint, because of the difficulty of getting paint to
adhere to metal under field conditions.

Linoleum has been successfully promoted for this same
general market with a considerable degree of success. It
is noteworthy that manufacturers of linoleum wall covering
have not attempted to duplicate the appearance of ceramic
tile, but have successfully promoted their product on its own
merits. Linoleum lacks the very high gloss which is char-
acteristic of glaze or plastics, and its range of colors is les^
brilliant. Linoleum does have excellent serviceability and
the required water resistance, even though it does show
some tendency toward becoming dull after a certain period
of time.

In evaluating the place of plastics in the market, it is not
possible to make too rigid a comparison of molded tile wittf
ceramic tile. The experience of older alternative materials
clearly indicates that a new product can be promoted in the
field, even though it does not duplicate the characteristics oj
ceramics. With polystyrene tile, inherent advantages should
be fully explored, and users and potential users should be
well informed on these characteristics.

Many Advantages to Polystyrene Tile

Polystyrene, for instance, is much lighter in weight thari
any previously used material. It puts less of a load orf
building structures, and thus shows less tendency to settling
and cracking. Its light weight also makes for lower han-
dling costs, and thus it is a more convenient material to
ship, carry and install. Polystyrene has extremely low wated
absorption, and when properly molded it is free from warp*
age and distortion. It is necessary that this material M
properly molded so as to avoid residual strains which cat)
cause warpage in storage or after installation. Mblderj
turning out polystyrene tile, however, are learning the tech-
nique and are now successfully licking this rather difficult
problem.

In tackling the building market, the plastics people arfl
dealing with an industry which is resistant to change and
in which old established practices are well entrenched. Re-
strictions affecting new materials form part of many labor
contracts in the field, and are written into many of the
thousands of contracts of the building codes in effect
throughout the country. Even more important, these prac-
tices are ingrained in the thinking habits of the men in thfl
industry. Any new product offered to the building trade
has this basic resistance to meet, thus pointing up further
the job which plastics must do.

Reactions are Favorable

Where resistance has been broken down, where the full
cooperation of builders, tile contractors, distributors and
dealers exists, and where the interest of the men on the job
has been obtained, results have been happy. For instance,
Levitt & Sons, one of the most progressive builders in the;
country, operating in various communities in Long Island,
have adopted plastics wall tile in one of their most recent
large projects. Three hundred kitchens and 600 baths in this
individual home project are being equipped with molded
plastics tile. The Levitt company, with a reputation for
quality, has taken this step only after careful investigation
of the properties of the materials.

It is also reported from Birmingham, Ala., that 124 new
homes being built there have molded polystyrene tile in the
bathrooms.

In Chicago, Titeseal Products Co. find that the product
has been "accepted very well and that customers prefer it
over other types of tile." In the same city, Artcraft Special-
ties Co. report objections that it is too glossy and that some
people are afraid of it because it is new. E. F. Ferguson
Co., also of Chicago, report that they are extremely happy
with the product. In seven months, during which a number

JANUARY 1948

of installations were made by this company, there has been
only one complaint. On the other hand, virtually every tile
contractor who has not handled the product has some ad-
verse comment to make. Both in New York and Chicago,
the amount of misinformation which is now prevalent is
evident.

The newly formed Plastics Wall Tile Association has
gone to work to set up specifications and to work with the
Bureau of Standards in establishing quality levels for prod-
ucts in this field. An engineering firm has been engaged,
and it is expected that progress in this direction will be re-
ported during the early part of the year. In the meantime,
the S.P.I, has set up tentative specifications, abstracts from
which are printed below:

Extracts From
Specifications Suggested by the Society of the
Plastics Industry for Wall Tile, Subject to Change

Polystyrene wall tile shall be construed to include all fabri-
cated polystyrene tiles designed for functional wall and ceiling
coverings.

GENERAL REQUIREMENTS

Polystyrene employed in the molding of wall tile shall conform
with ASTM specifications D703-44T and shall be of sufficient
opacity in its molded thickness to preclude irregularities of the
subsurfaces from being apparent on the finished tile wall.

The molding of tile shall be done in accordance with the best
accepted practice and so as to produce tile meeting the following
requirements :

(a) The surface of the tile shall be free of flow marks, shrinks
and blemishes.

(b) All tile of a given design shall be of uniform dimension,
free from warpage, and shall not deviate from their nominal
dimension in any way such as to interfere with installation or
detract from the appearance of the finished tile wall.

(d) The thickness of the finished tile shall not be less than
.055" but a thickness of .0625" would be more desirable.

(e) Aay manufacturer's tile shall conform with his standard
color charts without discernable deviation.

Polystyrene tile shall be so packaged as to reach the user free
I of breakage and without warpage or marring of the surface.

Polystyrene tile shall withstand 50 hours exposure in a Fade-
ometer without appreciable change in color.

I INSTALLATION DATA

The following represent installation data both as to materials
'and installation techniques, based on past experience, for maxi-
mum service in the use of polystyrene wall tile.

Application

(a) Tile condition : Polystyrene wall tile should not be in-
stalled at room temperatures of less than 70" F. All tiles should
be free from cracks, surface mars and gate lips.

(b> Mastic condition: All mastics should be at least 70 F
orior to use. They should be clean and thoroughly mixed.

(d) Wall condition: Polystyrene wall tile may be installed
over plaster, wood, cement, plywood, wallboard or any suitable
jorous or nonporous surface that is structurally solid. The walls
should be straight, smooth, clean, dry and free from high or low
spots. Corners, both inside and outside, should be square and
plumb. The wall need not necessarily be sized depending on the
properties of the mastic being used. Wallpaper, linoleum or oil
cloth must be removed and the paste washed off before the tile
is installed. Tile should not be installed over any surface which
is subject to moisture from behind unless the wall is adequately
waterproofed. It also should not be installed over cement or
plaster walls that are covered with a paint which powders when
it dries.

(e) Laying out the job: All jobs should be so planned that
the joint lines will be level at wainscot height. All cuts will
then come in the corners and at the floor and ceiling levels. If
special corner and cove base pieces are used the cuts will come
in the line of tile adjacent to these special pieces. If tiling a
ceiling and sidewalls, start from the center of the ceiling and
work four ways.

(f) Special precautions: (1) Water should be prevented
from getting into the supporting surface in back of the mastic
and tile. Effective means should, therefore, be taken to seal off
water entry around sinks, bathtubs, shower bases, etc. (2) Hot

HOW NEWARK DIE COMPANY
HELPED A FISHERMAN'S
DREAM COME TRUE . . .

.HE whole thing started when a practical-minded fisher-
man had a bright idea for a safe, handy gadget for holding and
carrying his hooks. Today his brainstorm is no longer just an
idea but a reality in HOOK PAK, an attractive and highly
useful plastic novelty with wide appeal to devotees of the rod
and reel.

Newark Die Company is proud of its role in the cast respon-
sible for the development and manufacture of HOOK PAK.
We designed and produced the master hob and hobbed cavi-
ties from which Dillon-Beck Co., Hillside, N. J., molded the
parts for the Gliebe Co., Brooklyn, N. Y., manufacturer of
HOOK PAK. The finished product and its accurate, econom-
ical manufacture are a tribute to the cooperation and know-
how of the three organizations.

HOOK PAK is another case history showing how Newark Die
Company serves the plastic industry. If you have a produc-
tion problem requiring multiple cavity molds, perhaps we
can help you. More than 25 years' experience in producing
thousands of compression, transfer, and injection type molds
qualifies us to turn out the hobs, hobbed cavities, and machined
molds you need.

air ducts, chimneys, registers, radiators, stoves, etc., should be
shielded or insulated so that the wall tile temperature never
exceeds 140F.

(g) Cutting the tile: Tile may be cut by guillotine type cut-
ters, by coarse-toothed hack or coping saws or by electrically
powered cutting tools. It should not be cut with scissors, tin-
snips, knives, or by scribing and cracking.

(h) Applying the mastic: The mastic should be combed on
the wall with a wavy motion by using a specially notched trowel.
The coating of mastic should be thick enough so that when the
tile is pressed firmly against the wall, the ridges of cement formed
by the notched trowel flatten and completely fill the cavity in the
back of the tile.

(i) Laying the tile: Installation may be made with a gouted
joint or laid edge to edge with no apparent joint line. Even in
the latter type of installation, however, the tiles should never
be set tightly edge to edge. There should be a slight space of
at least .005 between each tile. All tile should be firmly pressed
into place to insure good adhesion.

(j) Cleaning the tile: All excess mastic should be cleaned
from the face of the tile with a suitable cleaner before it has
dried.

(k) Wall fixtures: Towel bars, soap holders, paper holders,
pull bars, tooth brush holders, and any other accessories must
be of a type which are inset into the wall or are fastened directly
to the sub-construction. Under no circumstances should any
accessory be fastened to the surface of the tile.

(1) Finishing operation : As a final step of the installation it
is recommended that the tile surface be coated with a suitable
destaticizer and/or wax. END

Inflated Vinyl Display Manikins

(Continued from page 18)

100 Ib and cost from $25 to $100, while these new vinyl
forms weigh less than one Ib and cost $8.50 for the dress
size and $7.00 for the bust and shoulder size.

The collapsible manikin was developed as a result of dis-
play problems which Mr. Barbera had to overcome when
he was in the dress trade with his wife. He observed that
after a buyer has seen a professional model parade a dozen
styles, he forgets what the first style looks like. By using
the collapsible manikin, the styles can be constantly figure-
displayed while the model is making her various changes.
Although it will not make the human model obsolete, nor
is it intended to, the collapsible manikin will supplement the
model's efforts in showing the line.

Another important service the vinyl manikins perform is
that of providing salesmen on their out-of-town tours with
easy to handle figures that can be folded away in a corner
of their valise. In many towns where professional models
are unavailable, salesmen have only hangers on which to
show their, garments, though it often takes a figure to prop-
erly bring out the lines and details of a dress. The collapsi-
ble manikin is the answer to this problem.

Getting the idea for the forms was one thing; executing it
was quite another. For it was not a question of simply making
a balloon-like figure, but of producing one which bulged in
the proper places when inflated to resemble the human form.
A careful study of the placing of seams led to the develop-
ment of a plastics form that, within reasonable tolerances
not outwardly visible, was an exact duplication of the ana-
tomical proportions of the human body.

Seaming of the forms is accomplished on a custom-built
electronic heat-sealing machine. The finished manikin is
fitted with a self-sealing valve that keeps the form inflated
indefinitely and has the added advantage of preventing over-
inflation so long as manual means of inflation are used. To
take care of any leaks caused by pin punctures, the firm
supplies a repair kit consisting of a patch of vinyl film and
a thermoplastic cement that sets quickly.

At the present time Barbera works with Vinylite, using
100-yard rolls, 48" wide, from which 100 forms can be
made. One cutter, three operators and one mechanic turn

out 800 to 1000 forms monthly. In point of color, the firm
is currently stressing translucent film, but it will make the
forms up in pale blue, red, white, green, flesh, pink, etc., if
demand warrants.

Before going ahead with full-scale production on his idea,
Mr. Barbera brought samples to some of the biggest and
most exclusive dress manufacturers in New York to get
their reaction. In less than two weeks 600 forms were sold,
so that the company has been encouraged to plan a $50,000
advertising campaign in the trade and women's magazines.

Aside from the advantages noted above, the forms are
space-savers, too, for 18 garments can be effectively dis-
played on them on a circular dress rack occupying six
square feet of floor space. The form is suspended from a
Lucite holder which may be hung as well on any showroom
rack. Fitted with a swivel attachment on top, the form
rotates with ease, so that a prospective buyer may see the
back as easily as the front of the garment. Unlike ordinary
hangers, the form can be used to display strapless gowns,
which hitherto have required an expensive manikin fon
effective display.

For window display purposes, good effects can be
achieved by simply placing a small fan behind the light-
weight form to keep it constantly rotating.

An important potential application for the vinyl forms is
at home to keep cherished gowns in shape ; and it will pro-
vide an economical dress form for home dressmakers. END

Molding a Universal Handle

(Continued from page 24)

rking out developments is Linde Air Products. Edstrand
DS.. Sweden, hold the European exploitation rights. The
of the handle in these diverse lines indicates that it is ap-
:able to both free-swinging and fixed handles. Adoption
the handle by Hughes is interesting in that it shows that
new grip is not only pleasant where it relieves immediate
lin, but also in itself in the feeling it gives of a "natural"
d.

Accompanying this article is a chart indicating the vari-
i types of products for which the new handle can be used
good purpose. It should be noted that it is just as valu-
e for horizontally used products as the vertically sus-
ided luggage. On hand saws, for instance, the improved
p greatly reduces the strain and fatigue induced by the
itinuous back-and-forth movement. On stationary power
Is, many of which are quite heavy, the easy grip, while
annot reduce the force of the downward pull, does make
eel lighter, due to the equalization of strain on the hand.
s worth noting that a worker with heavy tools can use a
ve and still have the benefit of the grip hold,
rhe new handle is patented as trie Lamb Wedge-Lock
ndle a designation which becomes clear when its prin-
le of construction is explained. Essentially, it is based on
ll-established anatomical facts which indicate the amount
tension in each finger and in the hand as a whole when
s operating most efficiently.

-Vith conventional handles such as those used on luggage,
load is carried chiefly by the last two fingers, with some
p from the third and practically no help from the index

finger and the thumb, which literally sticks out like a use-
less sore thumb, even though it is being used "normally."
What actually happens is that it is wrapped around the
other fingers rather than around the handle and this, in
combination with the excessive strain on the other fingers
due to the imbalance, leads to quick fatigue, not only of the
hand but of the entire body.

The remedy, according to Mr. Lamb, lies in a design
which provides all the fingers with the kind of support
which allows them to bear the proportion of stress allocated
to them by nature. The practical result is a handle grip with
a deep groove at the forward end in which the thumb rests
easily without idling, while contributing to the power of the
hand the 35 per cent which is estimated to be its functional
share. The forefinger also yields its 20 per cent, and the
other three fingers are thereby relieved of the burden they
usually support. At the same time, the curve of the upper
surface of the handle is made slightly convex, to engage the
heel of the hand most effectively.

The wedge-lock idea came in when the handle was devel-
oped to serve both the left hand and right hand. These two
handholds call for reversely symmetrical curves in the han-
dle, but Mr. Lamb found they could not be incorporated in
one body unless a wedge-shaped partition were inserted at
the forward end of the convex surface mentioned above. This
made possible two diverging surfaces curved forwardly and
downwardly a design which allows thumb and forefinger
to carry their part of the hand's work most efficiently.

While a few industrial designers have intuitively hit upon
a thumb groove for various devices (see, for instance, the
article "Towards an Ideal Flatiron," page 48), Mr. Lamb
has been the first to justify it scientifically and give it a
precise form on that basis, in addition to providing a more
controlled surface for other fingers and heel of the hand. END

Since the manufacturing cost of the plastics stamp is
higher than that of the rubber stamp, size for size, the new
marker would tend to be confined to those applications where
positioning accuracy is important enough to justify the
higher cost. The differential lies primarily in the materials
costs since the wood and rubber are cheaper than acrylics
and vinyl. The disparity in fabrication costs, on the other
hand, is relatively slight. In the rubber stamp, the handle
is turned from dowel stock and a flat face is cut across the
head to receive the trade mark; the base block, processed
from lengths, is shaped and channeled to receive the sponge

rubber die-backing, is cut to length and is drilled to take the
handle ; the rubber die is molded in a vulcanizing press and ,
is cemented to the sponge rubber backing. Using ordinary
plastics fabricating procedures, the new plastics marking
stamp is produced as follows : the handle is turned from
acrylic rod and may remain frosted from the turning or
may be polished (either buff, dip or flash polished) ; the
base block is cut from acrylic sheet; the die is molded of
polyvinyl acetate in an engraved mold in a standard rubber
stamp vulcanizing press. Since the handle and base block
are both of acrylic, they are joined by a monomer-solvent
cement, with which the parts are soak -joined. The PVA
die is bonded to the acrylic base block with Dekadhese, ap-
plied to both parts which are exposed for a minute or two
until tacky and then put together until set. Acryloid B-7 is
another good bonding agent for the purpose, as is also,
though to a lesser degree, cyclohexanone. END

Promotion Must Be Many-Sided

(Continued from page 32)

Fig. 7. Dies needed for map marker functioning in Fig. 6

does not know how to capitalize on it. Few converters send
regular publicity releases about their work to the trade press
and participate in the shows of the industry. The neglect
of publicity may be due simply to carelessness or to a delib-
erate policy of secrecy. While the latter may be necessary
to a certain degree, it can be overdone. Witness the manu-
facturer who won't even say what material he is using in his
product. Point out to him that it takes only a simple analy-
sis often no more than a flame test to reveal his secret,
and he may say, "So I'm protected that much longer !" A
good wisecrack, but it gets him a black eye with the press,
as he will find out when he wants more publicity later on.
Besides, the converter who is afraid to impart essential in-
formation i'n a publicity release on his own product will find
that a competitor will do so and will also get the credit
for it.

Another kind of secrecy consists in withholding the name
of a customer whose product is featured in the converter's ad.
Along with other progressive converters, Creative Plastics
is dead set against this practice, not only as a matter of
courtesy but also in self-interest. For named illustrations
have greater credibility and therefore generally bring more
inquiries to the converter, and even some for the customer.
When these are passed on to the customer, he becomes
agreeably aware of the fact that the converter is doing a job
for him in more than one sense.

Salesmen, advertising and publicity can all go for naught,
however, if the converter does not. have the foundation of a
sound design service, as Mr. Harris sees it. Perhaps the
greatest service such a department can render is to free the
potential customer from the burden of making a blueprint of
the plastics component he believes his product can use. Since
he doesn't know enough about plastics, he is likely to draw
up his blueprint as if the medium were going to be wood,
brass or whatever material he is used to, and so he will
be wasting his time and posing needless difficulties for
the converter. All this can be avoided if the latter is in a
position to say, "Look here, my friend, you don't have to
bother with a blueprint. Give me a rough sketch of what
you want; give me a sample of your product; our designers
will work out a tentative solution for an efficient component
to harmonize with it in color and form; and we can .yive
you a bid on that."

A service as substantial as this costs money, it is true.
but the investment must be measured by its sales potential.
But unless design service is rendered, advertising, sales staff
and publicity will be selling a vacuum; and customers, like

I'LASTiCS

nature, "abhor a vacuum." In the last analysis, a product of
distinction must be produced in order to stay in business.

In sum, there is no one single factor which can build up a
business. It takes an all-around promotion program, which
includes planned advertising, planned publicity, thought-out
design, proper pricing and intelligent as well as forceful
selling. END

More Comfort
with a
Vinyl Pillow

Pillow made of "Vinylite" plastics is comfortable, long-
lasting, convenient to handle, free of dust and feathers

ANOTHER contribution to the comforts of modern life
has been offered by vinyl plastics, in the form of a
pillow. Two sheets of Vinylite with electronically welded
seams can be inflated to any degree of firmness or softness
desired, and a comfortable pillow with no lumps or bumps is
the result. When not in use, the Sleep Well Air Pillow,
which is claimed to outlast two ordinary pillows, can be de-
flated and folded to a convenient size for storage or for
carrying in a suitcase when traveling.

Free of dust and feathers which are a proven source of
allergy conditions the vinyl pillow is a boon to hay-fever,
asthma and other allergy sufferers.

One of its foremost uses is in hospitals, where its ease of
cleaning and sterilizing thus helping to prevent the spread
of contagious diseases and colds is so important. Resis-
tance to water, perspiration, sun and mildew are other ad-
vantages which the plastics pillow has over the conventional
pillow in use today.

The product is packaged in a transparent envelope and
shipped inflated, since the manufacturer felt it had greater
merchandising possibilities if the prospective buyer could
see what he was getting. A broadside is included with the
pillow giving detailed instructions for inflating, cautioning
against exposure to extreme heat or cold, and offering sim-
ple directions for sterilizing.

Manufactured and distributed by DuPage Plastics Co.,
Chicago, the Vinylite Air Pillow sells for $5.95, and is
guaranteed against defects of materials or workmanship. END

week at straight time. This idea he promoted two
years ago amid the screams of labor. It didn't
seem then as good an idea as it does now, when
we are all being swept by a spiral amid oppres-
sive taxation.

<! Some forceful action must be taken if the
spiral is to be arrested. And that action won't be
voluntary. Everyone wants stabilization, but not
at his own expense. If the next wage round be-
comes exhorbitant, as already is indicated by the
top labor leaders, why should business leaders
resist? Why not give in and raise their prices?
Labor will suffer most. The time for a crusading
executive to carry the torch again for stabiliza-
tion without the cooperation of government is
past. The national government must act, and en-
act real measures even in an election year.

* DRUMS vs. BAGS

<I In bags it costs less. Since the development of
strong multi-ply bags, some plastics materials
producers have adopted them enthusiastically and
have passed part of the saving on to the custom-
ers. Acceptance has not been as enthusiastically
shared by the entire industry, however. The drum
package still is most widely used. It is an expen-
sive one-shipment container, but it protects the
plastics from moisture, dirt and handling abuse.
The drums are heavy, difficult to stack without
proper equipment, and waste much valuable space
because they are round, although this makes roll-
ing simple. The cost varies around .7^ per Ib.
Although hard to inventory because the label is
always on the wrong side and the weights vary
due to the size of the drum, they do protect the
product for an indefinite period.
Q On the other hand, bags are light (usually 50
Ib). They are easily handled by one man and are
of standard weights, making inventory quite sim-
ple. Although unexpectedly strong, they do tear
readily. The moisture-proof liner keeps deteriora-
tion at a minimum.

Q The real savings in cost of bag handlings, how-
ever, result in the utilization of automatic bag-
ging equipment and the palletizing equipment.
Unfortunately, not many molders are using pal-
lets. Therefore, where they handle one drum,
they must handle three bags.
<| Several large companies are collecting cost
data to determine the savings, if any, in buying
plastics materials in bags. So far, results are
mixed. Some have switched entirely back to
drums ; others believe there is a savings. This
column will, as soon as available, report quoted
actual cost data now being accumulated.

* THE STOCK MARKET

<I Activity continues to reflect a cautious con-
servative mood. Year end tax-selling probably
contributed somewhat to December's downward
trend. Informed economists are discounting now
the smaller profits in 1948. Remember, the break
in 1946 preceded the break in the soft goods

often used in combination with .Fo.?ten'/e-resin-treated cotton
or asbestos cloth. Motors have been built with Fosterite-
asbestos molded vee rings and commutator insulation. How-
ever, double-flanged vee rings are difficult to mold, although
single-flange vee rings are easily formed.

Many sizes and shapes of coil-support channels are in
production. Rectangular tubes are made simply by wrap-
ping the treated paper around a rectangular mandrel and
pressing.

The process used for building commutators with mica in-
sulation can be followed quite closely when using Fosterite-
asbestos insulation. The seasoning sets of mica and Foster-
tte-asbestos are quite similar, so that the calculation for
shrinkage need not be changed. The material seasons a little
slower than mica. This necessitates about 25% longer time
in the seasoning ovens. If the seasoning temperature is
raised from 160 to 200 C, it seasons as rapidly as mica
does. END

is of clear cellulose acetate with a printed silver background,
the letters and numerals, however, being left clear and
transparent. It is backed by the second strip, which is of
translucent red cellulose acetate. When the phonograph is
turned on these strips are illuminated from behind, giving
the effect of red lettering on a silver background. The
"Make Selection" panel which lights up when a coin is
inserted in the phonograph employs the same principle.

Other decorative plastics include sprayed light shields
of heat resistant Plexiglas which frame the record changer
compartment, and a name plate of clear Vinylite printed in
red, white and green.

Wurlitzer depends on plastics for more than decorative
effect. Among the purely utilitarian plastics items are cable
clips of ethyl cellulose, electrical insulators employing pa-
per base phenolic laminates, noise-reducing worm gears of
linen base phenolic laminates, electrical contact housings
and contact carriers of compression-molded phenol ics, and
a time-saving transparent polystyrene switch cover which
permits visual check of the operation of a vital switch with-
out necessitating removal of the protective cover.

In helping reduce record and needle cost a major item
of overhead for phonograph operators and in preventing
accidental damage to records and pick-up, plastics do double
duty. Wurlitzer scooped the juke box field this year by
incorporating the Cobra Tone Arm, developed by Zenith
Radio Corp., in its 1948 phonographs. This revolutionary
tone arm has a polystyrene housing and, instead of a con- '
ventional needle, a "floating filament" housed in a cartridge
of the same plastics.

The use of plastics instead of metal on the Cobra Tone
Arm contributes to its light weight and the less than 2/3-oz
pressure on the record. This means that a record which
gives 50 to 300 plays with an ordinary pick-up will have
95% fidelity after 2,000 plays with the Cobra. The plastics
filament cartridge is retractable, and at the slightest pres-
sure the pick-up point is raised so that only the shoulder
of the cartridge rests on the record. As the smooth plastics
will not scratch the record, the pick-up can be dropped or
scraped across the record surface, the phonograph jolted
or moved without damage to records or pick-up.

Wurlitzer's 1948 line includes a new bar box which fea-

tures double injection-molded cellulose acetate butyrate mas-
ter key and coin entry numeral inserts, cellulose acetate
push buttons, a clear acrylic program window and a pro-
gram holder of compression-molded phenolics with record
title changer strips of red cellulose acetate. Two wall box
models have push buttons of tough acid-resisting Tenite II
butyrate. Auxiliary speakers in the Wurlitzer line also
utilize plastics for their decorative effect.

The Wurlitzer factory has complete facilities for forming,
cutting and assembling plastics components. In Model 1100
it fabricates the acrylic number roller window, the acetate
grille and the Plexiglas record changer window, which is
formed by the snap-back process in a vacuum pot. It is
interesting to note that, while the 24" long pilasters, the
S-shaped grille, and the decorative light shields in the
record changer compartment are suitable shapes for form-
ing in acrylics, Wurlitzer has decided to have them injec-
tion-molded instead in order to make savings in three ways.
First, there will be a reduction in the direct labor cost of
the operations, since molding eliminates much of the labor
required by forming. Secondly, there is a further economy
of labor cost in that molding also eliminates the need for
cutting and trimming; cutting was required because the
parts were formed two at a time from flat sheets. Finally,
there is the savings effected in material thus trimmed away.
Since the company uses large quantities of these sections, it
has been figured that savings will be appreciable despite the
higher initial cost of molds over forming dies.

Pilasters and S-shaped grilles are being molded for Wur-
litzer by Standard Products Company, Detroit, with Na-
tional Organ Supply Company, Erie, Pa., molding the deco-
rative light shields.

The thinking behind the extensive and imaginative use
of plastics in Wurlitzer phonograph equipment is expressed

by Paul M. Fuller, Wurlitzer's director of merchandise,
in this way, "Past performances of other materials, as well
as extensive research in the field of plastics, have led to the
use of the latter for very definite reasons. They have eye
appeal and animation because they lend themselves well to
color and light. They are used because of their beauty,
durability, light weight and their resistance to heat. No
other material is either versatile or inexpensive enough for
such general use as is made of plastics at Wurlitzer." END

harmonize with the colors of the enameled metal case and
cord socket, the base of the wheels being of black molded
phenolic which serves as insulator.

On the terminal boards, solder lugs are called for. These
components are made of phenolic laminate.

The tube for the air receiver extension is made of a vinyl
plastics chiefly because it is flexible and easily extruded. A
transparent hue was chosen because it best reflects the
various skin colors, thus making it quite inconspicuous. In
one type of earphone cord, the insulating material is poly-
vinyl chloride formulated with a non-migrating plasticizer.
Another type makes use of silk with a thermoplastic coating.

Although plastics are used so extensively in the Paravox,
there is no reason to assume that the present models repre-
sent the company's last word in plastics. They are only the
latest word. If one or another of the present plastics or
those in process of development can make a smaller or
lighter or less expensive component, this progressive hear-
ing aid producer will certainly use it. END

For Sealing in Plastics

Fry Plastics Company

7606 S. Vermont Ave., Lcs Angeles, California

Developed primarily to pro-
vide hobbyists and others
with an inexpensive means
for sealing a large variety
of objects in plastics, the
Hobbypress retails for only
$24.50 ; is claimed to produce
very high quality work.

A lightweight and com-
pact unit, the Hobbypress is
designed to apply loads up to
two tons. Objects up to 4"X
5" in size may be accommo-
dated between its precision
ground aluminum alloy plat-
ens. Pressure is accurately
controllable by means of a
heavy alloy steel spring.
Heating may be done in an
ordinary kitchen oven, over a gas burner, electric hot plate or
other similar heat source.

Press may be rapidly cooled by placing it under cold running
water or by immersing it in water. When using a hot plate
or gas burner, heating requires approximately 15 min. Cooling
takes only a minute or two.

The Hobbypress is ideal for sealing photographs, identifica-
tion cards and similar articles between sheets of acetate, acrylic,
vinyl, etc. As many as four articles 4"X5" in size may simul-
taneously be sealed when using the thinner plastics sheets, by
oven heating. If articles are smaller than 4"X5" so that two
or more articles can be placed in each layer, the total number
which can be processed at one time is correspondingly increased.
The press and its supplies are produced by Anstone Mfg. Co.
of Los Angeles ; and distributed by Fry Plastics Co., also of
Los Angeles (812)

New Gas Analyzer

Davis Emergency Equipment Co., Inc.
45 Halleck St., Newark 4, N. J.

Recently introduced for determining and analyzing the con-
centration of gases or vapors in their toxic range, the new
Micro-Gas Analyzer works on the principle of electrical con-
ductivity of solutions.

In operation, the gas is drawn into the analyzer by a small
pump. Gas passes through a flowrator and then enters a com-
bustion furnace where it is decomposed. From the furnace, the
gas passes into the cell through which the solution is being
pumped. As decomposed gas dissolves in the water, the electrical
conductivity changes. This permits a greater flow of current be-
tween the electrodes, which is measured on a meter in parts per
million of the gas being analyzed. After the solution passes by
the cell, it is pumped through a special unit which de-ionizes the
solution arid returns it to the cell in its original state.

The Micro-Gas Analyzer analyzes many different gases; read-
ings may be made directly and continuously for any of the toxic
gases by minor adjustments. By varying solution flow and air
flow, analyzations may be changed from one gas to another.

The unit, weighing approx. 33 Ib, is portable, and operates
from 1 10 AC 60 cycle current (813)

Standards for Electrical Insulation Material

Nonrigid plastics tubing made of polyvinyl chloride or its
copolymers with vinyl acetate has become quite a basic elec-
trical insulation material. Unfortunately, however, the electrical
and physical characteristics of these tubings have varied and
application problems have been frequent. The need for a stand-
ard is obvious, so the famous Standards Committee D9 of the
American Society for Testing Materials began a study of the
subject which resulted in an unusually interesting and useful set
of standard specifications. 1

The standards include data on color as well as on physical and
electrical requirements. The seven identified standard colors
are : clear transparent, black, white, yellow, green, blue and red.

The physical and electrical specifications provide that tubing
shall be checked for flammability, tensile strength, heat aging, oil
resistance, brittleness, lengthwise shrinkage, resistance to pene-
tration at elevated temperature, insulation resistance, dielectric
strength and wet dielectric strength.

In the analysis of these requirements, the report states that the
average tensile strength must be not less than 2000 psi, and the
average elongation not less than 200 per cent. The elongation
after immersion in oil shall not be more than 20 per cent below,

1ASTM nasignatinn D f)22-47 T, appearing in the 1947 issue of the ASTM Stand-
ards.

nor more than S per cent above, the average value for specimens
not immersed.

Brittle temperature must not be above 30 C. For tubing
sizes 20 to 17, the average shrinkage should not be more than
8 per cent, and for sizes 16 to 6 the shrinkage should not be more
than 5 per cent. Shrinkage is reduced to not more than 3 per
cent for sizes 5 and over.

A very complete table of dielectric strength values are offered
in the specs covering wall thickness from .012 in.' to .060 in.
The dielectric breakdown voltage for the .012 in. wall is 8,800 ;
.016 in., 11,200; .020 in., 13,600; 0.25 in., 15,600; .030 in., 17,600;
.035 in., 19,200; .040 in., 20,600; .045 in., 21,700; .050 in., 22,800;
.055 in., 23,600 ; and .060 in., 24,000. ' The average wet dielectric
breakdown voltage was specified as not less than 80 per cent of
the dry values.

A volume resistivity of not less than 10,000 megohms-cm was
established as a standard for insulation resistance.

A 15-sec duration of burning was adopted as a flammability
specification.

Discussing finishing, the standards stated that surfaces must
be smooth, free from blisters, cracks or any other defects such
as peeling, scaling or flaking which affect industry service.

Solutions tor Filaments and Yarns

Water solutions of polyvinyl alcohol have been used to manu-
facture a variety of filaments and yarns. To improve the quality
of these yarns glycerin and ethylene glycol have been used, but
a reduction in tensile usually resulted. In addition, the yarns, in
the main, became harsh and stiff. G. J. Esselen of Swampscott,
Mass., and Martin H. Gurley, Jr., of Newton Center, Mass.,
have discovered that feel of the yarns can be improved, with no
loss of tensile strength, with lauryl pyridinium chloride.

In preparing the material for the chloride application, a solu-
tion of about 25 per cent polyvinyl alcohol and 75 per cent water
is first made. To this is added a solution of from .25 to 2.50
per cent of lauryl pyridinium chloride, based on the weight of
the polyvinyl alcohol.

contain free amine which affects copper fittings in the yarn or
filament-forming equipment. It is necessary to neutralize such
free amine by adding small quantities of sulphuric acid, hydro-
chloric acid, etc.

In studying the adaptability of various anionic and cationic
surface active substances for yarn or filament improvement,
Esselen and Gurley discovered that while the cationic property
of the chloride was helpful, the improvement was basically due
to several peculiar qualities of the chloride, now being studied.

Heated Cutting Elements tor Thermoplastics

In another interesting plastics filament and yarn development,
F. G. Dodge, La Vale, Maryland, has found that heated cutter
elements of knives can be used to cut thermoplastic fabrics. The
heated cutting elements not only sever the fabric web, but also
seal simultaneously severed edges by softening or melting.

Thermoplastics which can be used include cellulose acetate or
other organic derivatives of cellulose, such as cellulose propionate
and cellulose butyrate, ethyl cellulose and benzyl cellulose. Also
useful are polyamides derived from the amino acids or from the
condensation products of diamines with carboxylic acid (poly-
hexamethylene adipamide) .

The cutting elements, of which there are three, are composed
of high-resistance metal as nickel steel, and made by bending a
wire in the form of a loop and curving to form a sharp cutting
edge. The elements are connected to a low-voltage supply.
Temperature control is affected by adjusting the length of the
resistance elements or filing the cutting surface of the knives.

New Elastic Textiles with Vinyl Resin Base

Vinyl resin elastic plastics research has resulted in the develop-
ment of many types of resin textiles which have high tensile
strengths in wet and dry states, and are resistant to water, alka-
lies, mineral acids and attack by micro-organisms. The textiles
are not inflammable and are excellent for electrical insulation.
Produced by processes developed by E. W. Rugeley, T. A. Feild,
Jr., and J. F. Conlon, these textiles are prepared by the conjoint
polymerization of a vinyl halide, such as vinyl chloride, with a
vinyl ester of an aliphatic acid, such as vinyl acetate, with the
resultant resin containing between 80 and 95 per cent by weight
of the halide in the polymer and having an average macromo-
lecular weight of at least 7500 and preferably 15,000 or more.

Feild has also found that rubber-like elastic yarn or fabric
plastics, which do not change shape, can be prepared by coating
vinyl resin yarn or fabric with an elasticizer or plasticizer, and
then fixing by heat application within a 40 to 110 C range.
Suitable elasticizers include the higher alkyl esters of dicar-
boxylic acids wherein each alkyl group contains at least four
carbon atoms, such as dibutyl phthalate, dioctyl phthalate,
methoxy glycol phthalate, dioctyl tetrahydro phthalate, dibutyl
sebacate, dioctyl maleate and dioctyl succinate, alkyl and
aryl phosphates such as tributyl phosphate and tricresyl phos-
phate, and polyglycol esters of carboxylic acids which have from
six to eight carbon atoms, such as triglycol di-2-ethylbutyrate
and triglycol di-2-ethylhexoate.

Feild has prepared elastic yarns by immersing a skein of un-
stretched vinyl resin yarn in dibutyl sebacate for ten minutes at
room temperature (about 25 C). Removal from the dibutyl
sebacate and centrifugalization follows to remove excess elasti-
cizer. Then the yarn is immersed, untensioned, in water (at
50C) containing a few per cent of a water-soluble soap, the
temperature of the water having been slowly raised to 81 C dur-
ing a 30-minute period. To complete fixation of the elasticizer,
the yarn is allowed to remain in the water for ten minutes. It is
then removed from the bath, and washed in water containing a
few per cent of water-soluble soap. Resultant yarn contains
about 34 per cent of the elasticizer and is quite elastic. Shrinkage
during heat treatment is slight.

The amount of elasticizer absorbed by the yarn may be con-
trolled by dilution of the elasticizer with a medium or low-boiling
solvent. A solvent or partial solvent for the resin, when mixed
with the elasticizer, accelerates the pickup of elasticizer by the
yarn. A solvent, which is non-solvent for the resin, when mixed
with the elasticizer, may retard the yarn pickup of the elasticizer.
Control of the elasticizer may be achieved also by regulation of
the temperature and the time of treatment of the yarn with the
elasticizer or emulsion of the elasticizer.

In another treatment method, Feild passed vinyl resin yarn
continuously over an emulsion roll on a standard winding ma-

chine. To fix the elasticizer on the yarn, a collapsible bobbin,
with the yarn, is placed in water-soluble soap solution at 50 C,
and the temperature raised to 70 C over a thirty-minute period.
The yarn is allowed to remain in the water for ten minutes to
complete elasticizer fixation, removed and wound from the bob-
bin. A steam-cell method has also been used for fixing, the
yarn being passed through a cell which is fifteen inches long, and
heated for .25 sec. to 107 C. The yarn is then oiled and coned.
The finished yarn contains about 40 per cent of the elasticizer
and is quite resilient. END

Hingeless
Cosmetic Closures

A LOCKING design has been devised in answer^ to the
complaints frequently heard from women -about the
locking element usually employed on plastics cosmetic com-
pacts. The closure is usually a hinged snap-lock in which
one plastics element of the lock rides over another a nib
over a nib, a nib over a rib, or an undercut over a lip or
shoulder. Closure is positive enough in the early stages of
use, but grip is lost relatively rapidly through frictional
wear on the locking elements.

A locking design that not only skirts this problem, but
also obviates assembly is found in a series of compacts
molded by Allied Plastics Corporation, Los Angeles. Instead
of a snap-lock, a progressively tightening friction fit pro-
vides closure. The principle, a cam-like construction, is
exemplified in the accompanying illustration of two items
in the Angelus line of the House of Louis Philippe, distrib-
uted by Affiliated Products, Inc., Jersey City, N. J.

New type compacts are closed by progressively tight-
ening friction fit, rather than snap-lock usually used

It will be noted that the curve of the bearing surfaces, in
both lid and base, is essentially spiral. When the box is to
be closed, the lid comes down over the base in a readily
located loose fit and the lid is given a short turn on the base.
Since the bearing surfaces of lid and base are counter-
spiraled relative to each other, they come closer and closer
together as the turn continues until they bear fully against
each other and lock frictionally. Further turning tightens
grip. In actual use, a mere flip will effect required closure.

The compacts illustrated, the smaller one 6.8 grams in
weight and the larger one 10.75 grams, were injection
molded of transparent cellulose acetate. END

Industr

Colo* Standards for Urea

A commercial standard for colors for molded urea plastics hai
been fixed by the Plastic Materials Manufacturers Association
Inc., and the Commodity Standards Div. of the National Bureai
of Standards, U. S. Department of Commerce. The new stand
ard, CS147-47, became effective December 15, 1947, after a two
year program of cooperation between the industry and th<
Bureau of Standards in establishing the list of 17 colors as now
adopted. A set of these colors can be obtained for $2.50 from the
PMMA, Room 731, Tower Bldg., Washington 5, D. C.

The establishment of these standard colors, it is believed, wil
facilitate the procurement of colored molded urea materials am
products. Through use of commercial standards, a more specific
designation of the exact color wanted will be possible betweei
molders, manufacturers and purchasers of goods. It will alsc
provide an easy method of ordering colors, and allow simplifiec
contracts with purchasers of molded products. Although thi:
is the first such official step in the plastics field, similar standard;
have been established in other industries, resulting ultimatelj
in fewer rejections of materials and finished goods, quicker de-
liveries, and lower inventories for converters. Commercial
standards also permit an interchangeability of finished products
with less hazard of obsolescence of consumers goods.

The adoption of standard colors is not intended to restrict the
production of other colors. Material manufacturers will con-
tinue to supply any colors desired when the amount required
warrants it.

The new standard defines the colors in reproducible terms,
specifies tolerances and provides for standard samples and des-
ignations to be used throughout the industry.

The spectrophotometric data on the standard colors, required
primarily for record purposes, will appear in the Commercial
Standard, mimeographed copies of which are expected to be
available by mid-February. They will be mailed to all acceptors
of record and to others requesting them.

Polythene Price Cut

The Du Pont Company has reduced the price of polythene
(polyethylene) molding powder by four cents per pound for the
uncompounded natural and the standard colors, making the price
on these respectively 46tf and 52tf Ib. Reduction for specially
compounded polythene or non-standard colors ranges from four
to seven cents per pound.

This is the fifth price reduction since Du Pont began polythene
production in 1943. The latest price decrease was effective as of
November 10, though it was not officially announced until the
26th.

Crystals tor Condensation

"EOF" crystals, described as a condensation product in the
reaction of ethylene diamine and formaldehyde and an extremely
reactive source of methylene bridges, is available in research
quantities from Rhodes Industrial Corporation, East Hampton,
New York. The compound can be used in place of "hexa" as
a setting agent in phenolic type resins, as a vulcanizing agent
for polyvinyl plastics compounds, as a crosslinking agent for
protein fibers, and generally as a new intermediate chemical.
New types of resins are said to be produced when the condensa-
tion reaction is effected directly between EDF and phenol.

German Synthetic Leather

A serviceable synthetic leather was produced by the Germans
from cotton and flax waste, hemp and ramie, with an acrylic
type resin, according to a report on German wartime develop-
ments published by the Office of Technical Services, Department
of Commerce. Mimeographed copies of the report (PB-1243)
sell for $2.

"Plastics from the Retailer's Point of View" was the subject
of a talk given at the November meeting of the New York section
of the Society of Plastics Engineers by Ephraim Freedman,
Director of Macy's Bureau of Standards. The four points for
which his store tests all products, Mr. Freedman said, were
adaptability, performance, durability and ease of care, and each
item is considered for itself, no matter the material it uses.

The molding of polyethylene and of vinyl chloride-acetate
(Vinylite) was discussed at the December meeting of the New
York section of the Society of Plastics Engineers by J. K.
Honish, Development Engineer, Bakelite Corporation. Mr.
Honish explained how the difficulty of molding the rigid vinyl
compounds can be overcome by proper engineering design, and
indicated some of the new fields of application.

The first meeting of the Education Committee of the Society
of Plastics Engineers was held at Princeton University on Oc-
tober 31, to discuss the educational needs of the plastics indus-
try and to develop an educational program for the guidance of
institutions interested in establishing curricula in plastics.

Agreement was reached on the basic principles and objectives
of engineering education at the professional level. It was con-
cluded that a thorough training in engineering fundamentals
precludes specialization in plastics in the time normally allowed
for a B.S. curriculum in engineering. Recommending that un-
dergraduate instruction in plastics be limited to introductory
courses, the committee suggested that specialization in this field
be concentrated at the graduate level.

The Education Committee is composed of an equal number
of industrial and educational leaders, as follows: Prof. J. M.
Church, Columbia University; Prof. V. C. Williams, North-
western University ; Prof. Fulton Holtby, University of Minne-
sota; Prof. R. K. Witt, Johns Hopkins University; John Del-
monte, Plastics Industries Technical Institute ; Prof. Hugh Winn.
Case Institute of Technology; Fred Wehmer, Minnesota Min-
ing & Mfg. Co. ; Dr. N. A. Skow, Synthane Corporation ; D. M.
Gray, Stoner Mudge Inc.; L. M. Hitchcock, General Electric
Co. ; H. W. Rose, American Viscose Corp. ; G. B Sayre, Boon-
ton Molding Co. Chairman of the committee is Prof. L. F.
Rahm, director of Princeton's plastics program.

Applicator made by Dorothy Cray.
Hyear part molded by Kirkhill Rubber Co.

THIS new lipstick applicator is
made of HYCAR American rub-
ber, improving the older-type brush
applicator. This brush will never lose
its bristles!

The designer had an idea and from
his idea may grow others for improv-
ing products or creating new ones.
Certain definite characteristics of
HYCAR met perfectly the require-
ments for the lipstick applicator. The
tip is flexible, and is resistant to grease
and oils. Unlike many types of rubber
it takes well to color, brilliant or
delicate. And finally, it is easy to
process. Even in very small molds
such as the one used for this product
the work can be precise, craftsman-
like, and beautiful.

Versatile HYCAR American rub-
ber has many qualities which make
it desirable throughout industry.
Latices of HYCAR may be used
as impregnants for paper or cloth
or as adhesives in a wide range of
applications. Its resistance to heat
and cold, weather and wear, mean
that it is among the most versatile
of modern products.

We make no finished products
from HYCAR or from other B. F.
Goodrich Chemical Company raw
materials. However, we'll be glad to

work with you on any special prob-
lems or applications. For more in-
formation, write B. F. Goodrich

AMOLDER of quality proprietary products re-
cently told of an interesting experience of one
of his salesmen. Trying to introduce a new item in
the company's line to a store buyer, he was turned
down. Why, wasn't the article attractive? The buyer
agreed it was very attractive, but said the price was
too high. Too high for a product so very well made?
Again, it was agreed that it was a solid job, but the
price was too high regardless. In witness whereof, the
buyer summoned a salesgirl and asked her if she could
sell it at the quoted price. The salesgirl said that she
thought she couldn't. But a customer on whom she
had been waiting happened to overhear the conversa-
tion. The customer's curiosity was aroused, and she
had a look at the new product. She liked it and or-
dered a set right there at the allegedly high price.

WE GOT A TIP the other day that B. Altman's.
the New York specialty shop, was using some in-
jection molding shots as motifs for'a decorative dis-
play.

This seemed to us an original idea, and we immedi-
ately investigated. It turned out, however, that the dis-
play pieces were really fabricated, in the form of a
picket fence, but, partly covered as they were by the
merchandise, they gave, to an imaginative eye, the ef-
fect of a sprue and runners. However this "false" start
shouldn't deter other display men from trying the real
thing. Many a multi-cavity molding shot makes an
attractive pattern, and we can readily envisage its use,
say in a notions department, to attract attention. We
think, too, that the public would find it stimulating and
interesting to the mind as well as the eye, finding out in
this way just how plastics come "hot from the press."

A WELCOME contribution to the education of the
public in plastics was made in a recent issue of
Look magazine. Under a large color plate of an in-
terior, the magazine ran the heading: "How Is Your
Plastic Eye Q?" The idea was for the reader to see
how many items he could identify as being made of
plastics materials.

A caption pointed out a few of them, and the com-
plete answer was given upside down at the bottom
of the page. More than 50 products were listed, of
which the average consumer would certainly not have

identified the majority of items as being made of
plastics materials.

The brief accompanying text began: "Look photo-
graphed a room, busy and crowded with furnishings,
visitor, child and maid, to prove that the uses of plas-
tics are limited only by the imagination of the men who
produce them and the people who use them. . . ."

WHILE WE'RE on the subject of education, an
item comes to hand which is pertinent to the
perennial problem of informative labeling. One of the
bugaboos for the plastics industry is the threat of an
overlong, overburdened informative label. Yet many
traditional yes, ancient products do not hesitate to
make use of a label as long as it is deemed necessary
to do so.

The item in question is the tag of washing instruc-
tions attached to a well-known line of woolen blankets.
It contains a numbered sequence of nine steps to be fol-
lowed, and these instructions occupy two whole sides
of the four-page tag, measuring 3^" X 4^". Of
course, no technical terms are involved, but only use
directions. There are many plastics products intended
for the consumer which can be labeled just as fully to
the advantage of the manufacturer, distributor and
purchaser.

PLASTICS PETE, booster extraordinary for the
plastics industry, is becoming reconciled to the ra-
dio. After gagging on corny gags, swooning crooners,
sappy singing commercials, much-ado-about-nothing
mysteries and slippery soap operas, Plastic Pete had de-
cided that he was going to live in the prehistoric past of
pre-1920, without benefit of radio. But, listening in
recently "just once more" to give radio its last chamv.
he was absolutely delighted to hear a good clarion-
voiced announcer the kind he had been damning all
along declare that the premium he was offering had
a "polystyrene magnifying glass." Just like that
polystyrene pronounced as easily and naturally as
"pretzels" and without stumbling. Plastics Pete could
hardly believe his ears. He wished he had had a re-
corder to make a permanent record of the epoch-mak-
ing event. He sat down to write postcards of congrat-
ulations to the station announcer and the premium
manufacturer. Plastics Pete is becoming reconciled to
the radio. END

"Plastics" sends its reporters info three
typical American homes in widely separated
parts of the country, to determine how
plastics are being used in normal everyday
living. Results of survey indicate that the
plastics market is far from being saturated
and that there is need for more educational
and promotional activity by manufacturers

TJOW ARE PLASTICS USED in the home?" is a
Jfj, question of importance to manufacturers who use
plastics in their consumer products and to merchandisers
who buy and sell them. Not how plastics can be used, but
how they have actually been accepted and put to use, is the
important thing.

Reports on new home applications of plastics materials
are carried frequently by this publication and by national
homemaking magazines. Recently, House Beautiful devoted
a large part of one issue to a presentation of virtually every
known use of the materials. It is more important, however,
to learn what plastics applications are in actual use in typi-
cal American dwelling places.

As one approach to answering this question, the editors
of Plastics arranged to visit three representative homes:
the families of a young farmer in Illinois, a junior profes-
sional man in the New York metropolitan area, and an
industrial employee on the West Coast were the first to be
interviewed. Although representing different localities and
varying interests and activities, the families are alike in
that they are all in the $3,000-$5,000 annual income level.

Without claiming a formal statistical survey, these fam-
ilies and homes can be taken as representative of a large
and important group of middle-class Americans. A con-
clusion can be drawn that the market for plastics is far fi
being saturated, and that there is room for more aggressive
educational and promotional activity by the industry and by

FEBRUARY 1948

From floor to ceiling, Mrs. Auld's modern, convenient and
well-ordered kitchen illustrates the importance of plastics

manufacturers using plastics to assure continued and grow-
ing acceptance of their wares.

THE AULDS OF STAMFORD. CONNECTICUT

The Aulds, typical of thousands of young couples in this
income range, are just getting around to the business
of building a normal family life, now that the war is over.
Married three years ago while Auld was a captain in the
United States Marine Corps, they returned to New York
after VJ Day, where he resumed his pre-war job as photo
technician for the General Electric Company.

Last year, they bought a four-room house that is within
commuting distance of Manhattan. It is a quaint hundred-
year-old cottage on a tree-covered hillside near Stamford,
Conn. They moved in late in January, 1947. Their first
child, Susan, was born in June.

"We have a few things in our home that are plastics, but
really, I can't think of very many," said Mrs. Auld, when
asked to cooperate in this survey. "We've only begun to buy
the things we need, and our furnishings are far from com-
plete." She was astounded when an accurate attic-to-base-
ment check disclosed 127 separate articles not counting
duplicates made, wholly or in part, of plastics.

On the theory that a new baby is always the most im-
portant person in any household, Susan's nursery was the
first room to be inspected. There were so many plastics
items here that it was obvious that, like the majority of
today's babies, Susan has been using at least one plastics
object almost every hour since her life began last summer.
She drinks milk from a phenolic-capped bottle. She plays
with a colorful variety of toys cellulose acetate rattles,
bright discs of urea strung on a chain, small polystyrene
animals, dolls made of plastics balls held together with cord.
Her bed is bedecked with a plastics "gym" designed to help
her exercise.

The mattress cover on her bed is made of vinyl-coated
fabric. The same material covers the padded bumper which
protects her head from injury against the side of her cradle,
as well as the pad on the floor of her new play-pen. When
she sleeps, her blankets are securely fastened with acetate
blanket-clips. There are many other plastics items in this
nursery tiny clothes hangers, a comb and brush, drinking
cup, talcum-powder box, soap container. Even the baby
carriage and the bathinette are made, in part, of fabric
coated with cellulose nitrate.

"From the first day the baby came home from the hos-
pital," said Mrs. Auld, "her diapers have been covered with
oblongs of vinyl film. They are easy to clean and don't
tear, even with repeated pinnings. As she grows older, I
keep pace with her size by cutting new covers from film
which I buy by the yard."

Homemade Vinyl Curtains

Vinyl piece goods was also used by Mrs. Auld in decorat-
ing the newly- installed bathroom on the second floor. She
made the unusually large shower curtain which completely
surrounds the bath tub. Window curtains are of the same
material, in a white and green pattern, which harmonizes
with the plain green shower curtain. "It's a pleasure to
have at least one pair of curtains in the house that can be
cleaned by simply going over them with a damp cloth,"
she said.

A glimpse at the medicine chest in the bathroom indi-
cated that plastics are used as at least a part of the packag-
ing of almost all medicines, pharmaceuticals, cosmetics and
dental cleansers. Toothbrushes, shaving brushes, combs
and hairbrushes, shaving-stick cases, thermometer cases
like most families.^the Aulds had scores of such items in
which the use of plastics has become so commonplace that it
is no longer noticed by the average personA

The Aulds' bedroom, which doubles as sewing room, also
holds its share of plastics. Mrs. Auld's transparent cellulose
jewel case held numerous pieces of plastics jewelry ear-
rings, a bracelet and several brooches. Her voluminous
sewing basket contained a colorful assortment of urea and
phenolic buttons, a plastics thimble and a tape-measure in a
plastics case. An acrylic handle decorated the top of her
portable electric sewing-machine.

Downstairs, the kitchen was still in the process of con-
struction, but the importance of plastics in this room was in
evidence from floor to ceiling. The flooring was vinyl
tiling, which Mrs. Auld likes because it is extremely tough
and scar-resistant, in addition to being slip-proof when wet.
Later, when counter-tops are installed, she hopes to have
them covered with the same material.

Plastics, in combination with metal, provided handles on
the shining new refrigerator and the deep-well cooker on
the electric range. The aluminum percolator, electric
coffee-maker and electric iron all had heat-resistant plastics
grips. Overhead, the kitchen light was diffused by a urea
reflector.

Kitchen Utensils Use Plastics

Cupboard doors opened to disclose a wide assortment of
plastics utensils: strainers, funnels, salt and pepper shakers,
measuring spoons and refrigerator containers. "And we
mustn't overlook our collectors' items," laughed Mrs. Auld
as she brought out a handful of plastics swizzle-sticks
garnered from various New York hotels and restaurants.

The combination living-dining room revealed less plastics
than any part of the house, but it did have several phenolic
ash-trays and an ethyl cellulose coated cigarette lighter. \
pair of nitrate-framed eyeglasses had been left on tin-
coffee table.

In a small alcove off the living room, Auld, for whom
photography is a hobby as well as the basis for his profes-

PLASTICS

FEBRUARY 1948

Vinyl-coated cloth play-pen pad and variety of plastics toys
are sanitary; can take wear and tear by little Susan Auld

sion, keeps his photographic equipment. From the view-
finder on his Speed-Graphic to the film holders, virtually
every article was at least partly plastics. The exposure meter
was enclosed in a phenolic cover ; the tanks in which the film
is developed were made of the same material, as were the
five filter cases and the camera case.

In the basement, Auld had begun to assemble a small
work-shop. On his work-bench were a power motor with
plastics controls, and a set of socket wrenches and assorted
screw drivers, all with plastics handles. The new oil-
burner in the corner had gleaming plastics frames around
its several gauges.

Throughout the Auld home, all 'wall plugs and wall
switches were made of phenolics, and many electrical cords
were plastics-insulated.

The family car had the usual assortment of plastics door-
and window-handle knobs, as well as a plastics steering
wheel, and radio and heater controls. In addition, Auld had
added an altimeter and compass, both plastics-encased.

What does Mrs. Auld, a typical home-maker, think about
plastics?

Reaction: More Than Satisfactory

She said, "In general, plastics are more than satisfactory.
I find them always amazingly easy to clean, whether it is
the plastics-coated pad in the baby's play-pen, the window
curtains in the bathroom, the tiled floor in the kitchen or my
nylon hose, which they tell me are really plastics, too. Then,
too, almost all plastics goods seem to wear extremely well."

She particularly likes the combination of strength and
lightness of weight which characterizes plastics household
articles. And she admires their wide range of clear colors.

But she had several suggestions for ways in which the
plastics manufacturer might aid the housewife and improve
the usability of his product.

"It seems to me that, until the average woman becomes
educated to recognize one plastics from another, each article
that is placed on sale should be plainly labeled with a
description of its virtues and its limitations," she said. "I
know that many things are labelled now, but I think this is
important enough to become a standard rule. And the
housewife should be encouraged to read the labels thought-
fully before buying. Then she will know, for example,
whether or not the plastics handles on a set of kitchen

knives and forks will come off if she washes them in ex-
tremely hot water. That sort of thing happened frequently
in the fairly recent past, and every time it does happen, all
plastics, the good and the bad, get a black mark on their
record."

She thinks, too, that manufacturers should take extreme
care to be certain that they use material which exactly fits
all the demands that will reasonably be made of the article.

Aulds Believe Educational Program Necessary

"Some women still retain a remnant of that negative re-
action developed during the war that plastics are some-
times 'ersatz' goods that substitute for something better,"
she said. "Of course, it isn't true any more; but it came
about when they bought such things as war-time sink-
strainers, only to have them curl out of shape the first time
they were used to drain boiling-hot vegetables. Housewives
will forget it in time but, until it is completely a thing of the
past, I think it deserves special consideration. This, along
with a program in magazines and newspapers to educate the
public in the new advantages of plastics, should do the
trick."

Misunderstandings between manufacturer and housewife
are not all the manufacturer's fault, Mrs. Auld believes. "At
least part of it is due to the way plastics wear out," she
said. "I remember a set of cellulose blanket covers I bought
a few years ago. They were transparent, of course, and ex-
tremely attractive. I used them for a long time, and then, all
of a sudden, they seemed to just disintegrate. They cracked,
became brittle, and finally fell apart. If they had worn out
gradually, as cotton does, for instance, I would have felt it
was simply the natural result of time and continued use. But
because of the way in which they went to pieces so quickly,
at first I felt as if I had somehow been cheated. Now, think-
ing back, I realize that they actually gave me good service

To decorate a newly-installed bathroom, Mrs. Auld sews show-
er curtains and bathroom window curtains of vinyl piece goods

Christie Conway's dresser reflects plastics' entrance into
the boudoir in combs, brushes, a watch box, bottle caps

for the amount of money invested. We seem to expect
plastics to wear forever, perhaps because so many of them
almost do."

THE CONWAYS Of INGLEWOOD, CAL.

Christie and Peter Conway live in Inglewood, California,
home of Hollywood Park race track and hatchery of some of
America's deadliest fighting planes. They have been mar-
ried six years, own their' five-room home at 3507 W. 115th
St., and have two normally rambunctious and more than
normally attractive youngsters, Gary, 4, and Bonnie, 2.

The Conways have had contact with plastics in more
than the usual fashion, yet this hasn't made them particu-
larly plastics conscious. They accept the new materials for
what they are and what they can do, without consciously
labelling them "plastics".

For about two years, Peter, a cabinet maker by trade,
worked in the saw room at C. D. La Moree, well known
fabricators of plastics products in Los Angeles. From there
he went to North American Aviation, Inc., where he has
been for the last six years. At present, he is leadman in the
wood shop, where a good proportion of the work is in con-
nection with plastics tooling. This takes two forms: build-
ing forms for the post-forming of various types of laminated
materials in which North American has always been partic-
ularly active ; and making forms for and performing finish-
ing operations on tooling which is made by pouring or cast-
ing cold-setting resins of various types. North American
has made use of this tooling to a considerable extent in
vacuum forming the acrylic canopies, bubbles and nose
enclosures for their ships.

Therefore, certain phases of plastics work are very famil-
iar to Peter. However, his knowledge doesn't extend far
beyond these workday contacts. He's interested in his work,
but there is his home, and the youngsters and Christie. In
his free time from the plant Peter is gradually remodelling
the house, making changes that enhance its livability. The
family car stands under a shelter beside the garage, because
that structure is completely devoted to Peter's shop (in Cali-
fornia there are no basements), and here he has drill press,
table saw, planer, joiner, router and sander, as well as the
myriad of hand tools every home workman accumulates.
Here, in addition to his work for the house, he pursues his
hobby, which is fine working in wood and decorative
plastics. Much of his work is in gifts for friends and
Christie, and in nice pieces for the home.

He has made several attractive cribbage boards by inlay-
ing half-inch pieces in Plexiglas, with the holes drilled, in
wood that has been worked to display the grain. Christie's
favorite costume jewelry piece is a heart-shaped pendant
Peter made for her in Lucite with an inset of rosewood. Clip
earrings match the pendant. Peter has a porch light in
process in the shop which is fabricated of a tube of ex-
truded Plexiglas set between a wood cap and base, and a
pair of very handsome table lamps. The lamps have wooden
bases ornamented with panels of Lucite YI" thick. On these,
Peter has engraved an intricate flower pattern using a
Moto-Tool hand grinder: This is his initial attempt at this
type of work, and is highly attractive and has^a professional
appearance.

In all his handcraft work, Peter uses plastics materials
where they fulfill his purpose and do a job better than an-
other material. If wood or metal fits his ideas more exactly,
he uses those materials in preference to plastics. The fact
that he makes such extensive use of plastics is testimony to
the great adaptability of these materials to home workman-
ship.

Peter has added much to the appearance of the house by

replacing the escutcheons behind many of the door knobs
with turned and polished plates of Lucite. Of course,
switch plates and electric outlets throughout the house are
molded of plastics, and Christie has protected the wall cover-
ing behind them in several places with shields of acetate
sheet. She is enthusiastic about this application as a work
saver where the youngsters are apt to smudge up the wall
paper turning the lights on and off.

Wonderful for Children's Products

Christie's greatest enthusiasm for plastics is in the chil-
dren's department. Oddly enough, one of .the few unpleasant
experiences she has had with plastics was in connection with
one of the uses about which she is most enthusiastic. During
the war she purchased some acetate tumblers. After little
use they crazed and sagged in the bottoms, and soon became
unusable. A new set was purchased, and these developed a
bad odor ! Christie doesn't know what the material was ; she
disposed of them, and now she has quite an assortment of
polystyrene tumblers and glasses, and is effusive in her
praise of them. For the youngsters, especially in the bath-
room, they are a real boon.

Another sad experience occurred during the war when
Gary was a baby, and formula had to be made. Funnels of
glass were unobtainable, and molded plastics funnels were
all of acetate or other unsuitable materials that became dis-
torted quickly under any kind of sterilization by boiling
water. Christie says it seemed as if she bought a new funnel
every other day. The need for that use in her family is now
past, and she is well satisfied with the service she now gets
from her polystyrene funnels.

Christie uses plastics dishes exclusively for feeding the
children. For this purpose she has several urea plates, and
also some divided dishes of the same material.

Object almost of reverence in the household is a dispenser
for kitchen cleanser which they received as a wedding gift,
and which has been in continuous service ever since. Molded
of thermosetting material, it has a rubber base that threads
into the bottom of the case. Apparently designed for a par-
ticular type of cleanser, it doesn't fit all containers precisely,
and they note now, sadly, and after six steadfast years, that
it is developing a crack in the lower edge.

Plastics in the Kitchen

Other objects in the kitchen which serve so well they are
taken for granted are a molded Lucite cake knife, cookie jar
formed of acetate sheet with wooden base and pressed metal
cover, gaily decorated, a wide assortment of cookie cutters,
measuring spoons, egg cups molded of acetate and somewhat
out of shape from contact with the hot eggs but still usable,
a set of measuring cups by Hemco, and a Rochovv Swirl
Mixer molded in polystyrene.

Their Gaffers and Sattler gas range is equipped with a
B.ridget timing clock which has a plastics case, and the
knobs on the range are all of molded plastics. Likewise
molded are the handles on the Proctor toaster and on the
Sunbeam Mixmaster. The Mixmaster also has a molded
adjustment knob. Plastics pulls decorate the kitchen drawers
and cabinets.

Mr. King of the Hamilton-King Co., manufacturers of
non-spill desk sets, has his shop in the next block back of the
Conway's home, and Peter has helped him from time to
time. As a result, there are several of these attractive
molded desk sets about the house.

The family radio is a Sonora table model which they got
last Christmas. Its case and control knobs are molded, and
the tuning band is protected with an acetate sheet strip.

Christie is also very enthusiastic about her shower curtain
and bathroom curtains made of Koroseal.

The entire family is equipped with Fuller molded tooth-
brushes, and each member also has a hairbrush with molded

Lucite back and nylon bristles. In addition, Christie has a
facial brush and a nail brush. There are, of course, an as-
sortment of .combs about the house, one of which is molded
of nylon.

An assortment of cosmetic boxes and bottles, some made
entirely of plastics materials, the majority of glass with
plastics closures, decorate the dressing table. She has an
attractive box for her two watches which is molded of
acetate. A wide decorative belt is of a plastics coated mate-
rial, as are two of her handbags.

In the children's department, plastics toys dominate the
usual conglomerate heap of playthings all children seem to
accumulate, especially among the small objects that are so
endeared to very tiny tots. Dishes and doll furniture are
much in evidence. There is also a bewildering array of auto-
mobiles, trucks, fire engines, trailers, airplanes, tractors and
wagons. Both children seemed fond of molded soldiers and
especially so of the "Skipper" ducks. Bonnie has a little red
purse, made of plastics-coated material like her mommy's,
which is dear to her heart. Both Christie and Bonnie wear
molded acetate barrettes, of which they have a large collec-
tion in many sizes, shapes and colors. <

Enthusiastic Over Plastics Toys

Both parents are enthusiastic about plastics in toys. They
like the lightness and smoothness, and especially the high
degree of safety plastics insures to the children and to the
house and furnishings. As they point out, a plastics toy
seldom breaks in such a way that it is dangerous to the
children, and the lightness and smooth surfaces achieve a
minimum of damage to walls, furniture and fabrics.

They are also grateful for their collection of children's

also in short supply; low priced synthetic rubber is in
greater demand. Result : Polystyrene will be critical if
the demand continues at its present high level.

* THE DAWN

<I Two men who were in the business of jobbing plas-
tics merchandise during the war years had been kicked
around by the molders so brutally, that when the op-
portunity presented itself they couldn't wait to set up
their own molding plant. They consulted your com-
mentator, who advised them not to entertain such an
idea, because they would have to become concerned
with plant problems about which they knew nothing;
their merchandising skill would be thwarted, and their
capital would be tied up in plant machinery and equip-
ment.

<I Although they are in business today, and very suc-
cessful, they have analyzed their position and deter-
mined that, had their efforts been confined strictly to
design and selling, not only would they now have cash
instead of machinery, but they would also have more
overall profits and fewer headaches. Their reasoning
is that for the equivalent of the investment in each ma-
chine, they could be creating several new articles, which
would produce more income than they can save by
molding themselves. They conclude that custom mold-
ers, skilled in molding, could be producing their parts
better, cheaper and faster.

<I Because their assembly costs greatly exceed their
molding costs, they can well afford the luxury of a
molder. A $10,000 mold and a $15,000 injection mold-
ing machine will not reproduce $25,000 in profits as
fast as will $25,000 in molds, an outside molder and
their ability to design and sell. Their conclusions are

* A MARRIAGE OF NECESSITY

<I Another year has slipped by, and the marriage
of SPI and SPE seems to be further off than ever.
The engineers' group apparently considered the
latest offer by SPI as a kind of shotgun affair, and
declined to accept it. The alliance might not be
as urgent now as it was a year ago if the various
SPE sections could continue to serve local areas
as successfully as they have in Newark, Erie,
Detroit and some other cities. As independent
groups, they could further the interests of the
professional man, the little man the man forgot-
ten by SPI.

I But in order to sustain their success, the
SPE chapters would have to be guided with the
enthusiasm of the directors who founded them.
The new year will see a change of directors, and
we cannot tell whether the newcomers will keep
pace with the hard-working, imaginative men who
preceded them. Without a strong central body to
buoy them up and cushion their losses, we cannot
be too optimistic about the future of the SPE
groups.

<J Already weaknesses are appearing. For one,
the national organization is too busy meeting ex-
penses to do much for the individual sections. The
present heads of the organization have made su-
perhuman efforts to spark it. They have wiped
out the deficit from last year's ill-conceived show.
They have seen some chapters growing like brush
fires, but they have also seen other chapters pe-
tering out from neglect, without being able to do
anything about it.

<I It, therefore, seems imperative for SPE either
to have a strong central organization of its own,
or to become allied with one. . The industry has
confidence in SPE, admires it and wants it to sur-
vive, but on its own merit and not by a constant
fight for survival. Can't the joint committees
bargain, negotiate or even arbitrate until a settle-
ment is reached in 1948? That is most certainly
the hope of a large segment of the plastics indus-
try.

* UP AND THEN DOWN

I Fourteen leading economists, questioned hy
the National Industrial Conference Board about
their views on the Business Outlook for 1'MS.
forecast industrial production at generally high -T
levels for the first six months, but lower for the
second six months, than in 1947. The same pre-
diction was made for other important indices :
national income, gross national product, corporate
profits, retail sales and wholesale prices.

<I With such an outlook, why does industry cmi
tinue to expand? Answer: American businessmen
are eternal optimists, like each American soldier
who, when being told that two out of every three
on some dangerous mission would not come back,
looked around and said, "I'm going tn miss you
fellows."

"CCA" Makes
Fire-Resistant
Panel Material

Used as a sandwich material between two
layers of carbon steel, cellular cellulose
acetate makes a panel which has stood up
under rigorous tests made by the Civil
Aeronautics Administration. Developed
first for use in aircraft, many potential
applications lor this new material are
being foreseen in ships, hotel room doors,
building .partitions, various other places

Effectiveness of new fire-resistant paneling is demonstrated
by M. K. Weill, president of Skydyne Corp., who sits com-
fortably within inches of roaring gasoline and fuel oil flame

AFIRE-RESISTANT panel with such high heat in-
sulation value that it protects human flesh within one
inch of flame has been announced by the Skydyne Corpora-
tion and the DuPont Company. Pyroply, as the new material
is designated, has been developed initially for use in aircraft,
but application to ships, building partitions, hotel room
doors, and other uses^are foreseen.

The new material consists of cellular cellulose acetate
sandwiched between sheets of carbon steel each only .006"
thick. In official tests conducted under Civil Aeronautics
Administration specifications, panels with an overall thick-
ness of J4" withstood heat in excess of 2220 F.for more
than 30 minutes. At the end of that time the hand could still
be held without discomfort near the panel on the side oppo-
site from the fire. It is noteworthy that baking ovens seldom
exceed a heat of 550 F.

High Strength Low Weight

The high heat insulating effect is derived in part from the
cellular nature of the plastics sandwich, which is specially
treated to further increase fire resistance. In combination
with the thin carbon steel, the product provides high
strength with very low weight. A child can lift a large sec-
tion, which is strong enough to support the weight of a
heavy man.

Attention of the Skydyne Corporation has been concen-
trated largely on aircraft where the need for flame re-
sistant paneling with high structural strength is so evident,
but the new material presents important potentialities
wherever its combination of properties is needed. Pas-
senger and freight ships are typical of such possible
applications. END

Phenolics Break into

Paint Brush Field

A MILLION piece order of molded phenolic handles
by the Baker Brush Company, New York City, has
provided the entering wedge for plastics in the ultra-con-
servative field of paint brush manufacture. Wary of inno-
vations, this industry has given the nod to but two major
changes in the past 50 years the use of nylon bristles, and
the use of vulcanized rubber as a binder for bristles.

Although phenolics have been regarded as a "natural"
for paint brush handles for many years, manufacturers in
the highly competitive field, mindful of their costs, have
balked at bearing initial mold costs. It took an enterprising
molder, Mutual Metal & Plastic Corp., Brooklyn, New York,
to take this calculated risk, and they have broken into the
paint brush field with a development which may well over-
take the earlier two in importance. About 50 million paint
brushes of all types are produced yearly, at a cautious
estimate, and since phenofic handles can be marketed at a
price competitive with wood, there is no foreseeable reason
why they cannot capture at least the major part of this
market. The first production run for Baker is mostly in
the 1", 1 J4" and 2" popular size for household use.

Phenolics were chosen for this application because they
show negligible changes in weight or dimension when im-
mersed in the common paints, solvents and thinners. Though
this is rather widely known, both Mutual and Baker estab-
lished the fact to their own satisfaction. Mutual submerged

An innovation in paint brushes a phenolic
handle is welcomed by distributors and users.
The physical and chemical properties of this
molded plastics have made it far superior to
wood for this application, and have also made
possible production and assembly economies

both wood and phenolic half -inch brush handles in a can
of lacquer thinner for 24 hr. While there was no detect-
able change in the plastics handle, the wood handle lost its
color, gained 4J/2 grams in weight, and increased between
15 and 20 mils in thickness. Baker relied on the objective
report of a well-known testing laboratory stating that phe-
nolic handles are unaffected by all common paint materials.
Nevertheless, the rumor is still given currency in some
paint quarters that plastics "dissolve" in paint materials.
The basis for this rumor is that some time ago various
thermoplastics were molded on an experimental basis for

(Upper left) plastics handle now made; (Lower left) blocked-

use as brush handles, and were unsuccessful. Those who
are circulating these adverse reports have not taken the
trouble to inform themselves that phenolics are quite differ-
ent from thermoplastics and do not "dissolve" in paint. Or
it may be that the whispering campaign was deliberately
conceived in an effort to bar the door to the plastics new-
comer.

As the tests run by Mutual indicate, it is really the wood

handles which are adversely affected by paint chemicals.
In addition, after wood handles have been repeatedly washed
and dried they have a tendency to shrink, loosening their
connection with the metal ferrule. Moreover, wood handles
which have been painted or lacquered to increase their at-
tractiveness will soon lose their color in contact with sol-
vents and thinners. Although the order from Baker is being
produced only in black for economy sake, it is a permanent
molded-in black ; and Mutual is also molding a sample line
in various colors.

Paint Easily Removed

Another advantage of the plastics handle is that paint
accumulated on it can be easily removed, even when dry,
with a damp cloth, whereas on a wood handle paint cakes
up, sometimes making the brush cumbersome.

For use with the popular water emulsion paints, phenol-
ics are superior to wood since they do not change in weight
or dimension when in contact with water, as wood does.
Mutual immersed both a maple and a birch handle in water
for 24 hr. Both handles swelled up and, when dry, con-
tracted. When the test was repeated, the birch handle ac-
tually buckled.

Besides the advantages of the physical and chemical
properties of the plastics material, the new brush also bene-
fits from the economies which the molding process makes
possible.

Working in close collaboration with its first customer,
the Baker Brush Company, Mutual planned the plastics
handles with the thought of eliminating production bottle-
necks encountered in the manufacture of wood handles, and
also of creating advantageous features not feasible in wood.

One of the outstanding advantages of the phenolic handle

is that it can be molded to c'.ose tolerances, giving finished

products with uniform dimensions. Lack of uniformity has

long been the major bugbear of brush manufacturers, es-

What's in a Came?

'illiam

Plastics Field Editor

A new gome is based on a novel idea and a
thorough exploitation of plastics materials.
A detailed promotion program was worked
out, though market was not tested in advance

Interesting table quoits game makes use of polystyrene, two kinds of vinyls, and extruded and sheet acetate

THIS STORY about a new game called Scor-A-Peg
will not be encouraging to operators who, with half an
idea and $195 of capital, try to break into the lucrative but
exacting game manufacturing field. It should, however,
buoy up those who have been struggling along with a sound
idea, trying to develop its maximum possibilities and
financing it properly, rather than going off half-cocked be-
fore the product has been whipped into shape for both pro-
duction and exploitation.

More particularly of interest to our industry, Scor-A-Peg
is testimony of the faith of its sponsor in plastics materials,
and of his untiring efforts to find the right plastics for each
of the many components of his game a quest which brought
many plastics converters into the picture : materials sup-
pliers, model makers, molders, fabricators. He is Carl
Lapin, Playday Toys, Inc., New York City, who developed
and styled the game, which was conceived and patented by
George Mysels. A bizarre aspect of this story is that Mr.
Lapin not only took advantage of the cooperation of the
various factors in the industry referred to above, but is
actually grateful to them he considers them his collabora-
tors in selecting the proper plastics and producing the
components most effectively.

This perfectionism, carried over also to a completely laid
out program of marketing, has resulted in an undertaking
entailing an investment of $125,000, a large part of which
has been expended before the game has even reached retail
outlets.

Of this sum, $100,000 will be absorbed by mold, material
and other production costs, and the balance by promotion.
Furthermore, reversing the usual procedure, this game has
not been pretested on jobbers and store buyers, but is being
offered to them as an accomplished fact, with a first produc-
tion run of 100,000 available to fill their orders.

However, the game was demonstrated before the Con-

sumers Service Bureau of Parents Magazine, and received
that organization's seal of approval. Also, an authority was
consulted on the $3.98 price, and he pronounced it "very
favorable, provided that the game has eye appeal, makes
sense and represents good value."

Scor-A-Peg is a kind of table quoits. As the illustra-
tions show, it is contained in a box, one part of which is
designed with 15 molded-in pegs onto which the players try
to propel a ring, with a flip of the second or third fingers,
from the "plateau" at the far end of the other part of the
box. To facilitate the play, there is a rise opposite the
"plateau" which lifts the speeding ring into the air so that
it may come down on the pegs, and the peg compartment is
propped up by an easel to make an inclined plane. There
is also a net above this to deflect a high-flying ring and keep
it within the confines of the game, giving the player another
chance to score with it.

Many Design Possibilities

Though the game is simple in principle, it obviously has
many design possibilities, both functional and decorative,
and it took more than a year to resolve them satisfactorily.
While the basic design was being evolved, variations of the
game were developed which enhanced its usefulness and,
therefore, its sales possibilities. In effect, these were created
by means of templates fitting over the pegs bearing the sym-
bols of playing cards, bowling pins, football players and
baseball players. With the first example, called Pok-A-Peg,
containing 15 cards ranging in value from 10 to ace, a kind
of showdown poker can be played. Similarly, the other
variations Bowl-A-Peg, Peg-A-Goal and Pcg-A-Base
make for games in the spirit of bowling or football and
baseball, respectively.

Materials used in the components of the complete game
consist of: (1) game shell, or box, (2) easel or prop sup-

I'LASTiCS

porting the peg compartment, (3) backstop or net, (4)
rings, (5) score pad, (6) templates, (7) a two-color, 24-
page booklet describing the game, (8) the package.

( 1 ) The shell or box is, of course, by far the largest single
component of the game. The use of plastics was indicated for
it on many counts. First of all, being required in large
quantities, it could be molded economically, and molding
makes possible the inclusion of all the structural elements
in one operation the pegs, the "plateau" and rise, the holes
in which the backstop poles are inserted and, finally, a last-
minute development not shown in the model photographed
a molded-in ridge which provides a storage rack for the
rings in the "take-off" compartment.

A plastics shell could be made which would not warp,
which would be more than strong enough to stand up under
ordinary wear and tear, and which would not be discolored
on exposure to sunlight in store windows. Plastics would
also have such other desirable properties as light weight,
odorlessness and resistance to water and such chemicals as
might come in contact with it.

Metal inserts could be molded-in which, in combination
with molded tabs on the cover, provide a snug closure fit.

The rings around the pegs, setting them off .to better
advantage, could be hot stamped into the material and in
the same color as that of the other half of the shell, offering
a neat decorative value.

Plastics Offers Wide Cofor Range

Finally or maybe this should have been "first of all"-
the use of plastics and the molding process allow the shell
to be produced in a wide range of colors and color combina-
tions that is, the two parts can be turned out in different
colors. The initial run will yield shells in black and orange,
blue and red, red and white, and yellow and green.

Thus, people who have game rooms with a definite color
scheme can choose the Scor-A-Peg combination which har-
monizes with it, and people who play it on the dining room
table can select the colors which appeal to their taste.

The material chosen for the shell was Kopfers poly-

styrene, both on a cost and properties basis. Watertown
Manufacturing Company, Watertown, Conn., will produce
it in three-cavity molds on 22-oz Lester injection molding
presses. One of the problems met up with in the production
of so large a piece (weight is one Ib three oz), was the
formation of gas and hot air pockets. To avoid unsightly
apertures, vents were created by means of pinpoint holes at
the top of each peg. The molding cycle is little over one min.
Long before Watertown made the dies, however, a set of
models was built to make a preliminary engineering study
of the production possibilities. These models were made of
acetate in various colors by Stricker-Brunhuber Company,
New York. At the very end of the development, another
group of eight models was created from which kodachromes
were to be taken for use in ads and promotional literature.
This second batch was made by AS Plastic Model Company,
New York, from compression molded polystyrene sheets
produced on special order to .090" thickness by Willson
Plastics Div., Willson Magazine Camera Co., Philadelphia.

(2) For the easel or prop, Mr. Lapin sought a suitable
plastics also, but in the end it seemed to be simpler and more
economical to make it of 12-gauge steel, nickel-plated. Fit-
ting into a molded-in hole on the under side of the shell,
the easel is well rounded so as not to mar the shell, or the
furniture or the hands of the players.

(3) An attempt was made to procure a plastics for the
backstop or net, but it was not feasible to mold or punch so
many apertures in so thin a piece, and the backstop is there-
fore being made from a cotton fabric impregnated with
starch. The poles, however, which act as dowel pins, are
Koppers acetate rods extruded by Werner Extruded Plas-
tics Co., division of R. D. Werner Company, Inc., New
York.

(4) Plastics for the production of the rings seems obvious,
yet the choice of the right one was difficult. It wasn't only a
matter of getting an easily moldable and colorable plastics
the range of choice was wide in these respects but one
which would not bounce on the shell surface. This would
make it difficult for a player to score, since the rings would
leap off the pegs, and he would be discouraged an undesir-

able feature in a game for youngsters. Vinyl seemed the
right material, and the B. F. Goodrich Chemical Company
worked out a Geon formulation which is inelastic and yet
flexible. This compound is being injection molded in 20-
cavity dies by Sterling Plastics Company, Union, New
Jersey, on 4- or 6-oz Lester presses. Weighing 1/20 oz, the
wings are produced at the rate of 50 per min.

(5) The scorepad is printed on good paper stock.

(6) For the templates, a material was required which was
sufficiently rigid so that it could be pressed over the pegs and
removed frequently without bending or tearing. It also
wanted a surface which would print clean and clear. White
Vinylile of .010" gauge was chosen. It is lithographed in
one color, press polished on both sides, and die cut into
triangular shapes, with 15 holes blanked out for the tem-
plates to fit onto the pegs. All these operations are carried
out by The Emeloid Company, Inc., Hillside, New Jersey.

(7) The Story Book describing the game does not call for
plastics, but it is interesting to note that Mr. Lapin has
worked into it a brief account of what plastics are.

(8) For packaging the game, a good grade of box board
was selected which, after it is printed, is given a Lamcotc
cellulose acetate lamination by the Arvey Corp., Jersey City,
New Jersey. This not only protects and strengthens the
package, but gives it a true plastics finish in harmony with
the plastics nature of the contents.

A summary of materials ordered for the first run of Scor-
A-Peg, in addition to corrugated shipping containers, fol-
lows: over 100,000 Ib Koppers polystyrene molding com-
pound for 100,000 shells ; 2,000 Ib Geon polyvinyl chloride
molding compound for 500,000 rings; 1,000 Ib Koppers ex-
truded acetate rod for 200,000 dowels; 3,000 Ib Vinylite
sheets for 200,000 templates; 5,000 Ib paper for 100,000
books; 20,000 Ib of paper for 100,000 score pads; 22,600 Ib
patent coated box board for 100,000 cartons (to be lami-
nated with cellulose acetate) ; 1,700 yd fabric material for
100,000 nets; 2,800 Ib bright nickel finish wire for 100,000
easels. Mention might be made of the special inks com-
pounded by Interchemical Printing Ink, division Interchem-
ical Corp., for use on cartons to match colors of the polystyr-
ene shell. In Mr. Lapin's calculation, mold costs are amor-
tized over a 300,000 production run.

The same degree of planning that went into the construc-
tion of the game entered also into its promotion program.
For the first point of sale, the manufacturer is sending every
toy jobber and store buyer one box of the game, a composite
photograph showing game and package as a display unit,
and a promotional letter, with mats to be made available for
those who wish to advertise the game.

For the second point of sale store to consumer the
package was designed with great care. Since it is the pack-
age which shows in counter and window displays, it was not
only made solidly and plastically as described above, but it
was designed in eight different colors and combinations to
match those of the shell within, and groups of packages can
be arranged to form designs of their own. Cartons are made
by International Folding Paper Box, North Bergen, N.J.

As a further inducement to stores and jobbers to promote
Scor-A-Peg, extensions of the game are planned which will
give it a continuing life. Reference has already been made
to the four templates which provide variations on the
original game. These are only a beginning of a Scor-A-Peg
Game Library. The additional units are to be issued in
packages of two templates of four games (lithographed on
both sides), selling at SOf the packet.

Deliveries of the game are to be made by early spring, so
that it will reach the consumer by the end of May. It will
be presented to the trade through the Bernard Funk orga-
nization, New York, which has the exclusive national sales
rights. This company will maintain a standing exhibit of
Scor-A-Pcg at their showroom. END

Timber
Progressing

An important development is faking place
with the manufacture of synthetic timber
made by bonding airborne bacteria with
water and wood Hour. Samples are very
tough, withstand a pressure of 3,260 psi

THE REPORT of a synthetic timber named Castwood
produced by bacteriological methods (Plastics, Oc-
tober 1946) can now be amplified on the basis of samples
shown in London by Castwood Co., Ltd., patent holders and
manufacturers. These are being distributed to a number of
furniture factories for practical tests for suitability and
potentialities. Although first reports led to exaggerated
prospects, there is a very solid basis on the evidence pre-
sented by the company to justify the belief that an important
development is pending.

Castwood was invented by Edmund Herrmann, a Ger-
man scientist now working in Britain and a director of the
company, along with Reginald Stamp and Thomas Gardner.
It is manufactured by bonding airborne bacteria with water
and wood flour. In an hour this combination becomes solid
timber, comparable to naturally matured timber in many
respects. It is indicated that neither heat nor very high
pressure is used in its production, and that it is not a plastics
material in the normal sense but a purely natural product.

The samples on display are extremely tough, and capable
of withstanding a pressure of 3,260 psi. It is water- and
fungus-proof and heat-resistant, and will take a polish com-
parable to that of many fine natural timbers.

Although in the early stages of its production Castrvood
is soft enough to cut with a knife, it hardens to a solid mass
which can be sawed, drilled, cut or planed. It can also be
molded to any desired sha^e in an ordinary cold press.

Production is beginning at Bio-Plastics, Ltd., where
boards of the new material will be cut into timber parts,
polished, grained, and supplied in this form to manufactur-
ers who will only have to assemble them in order to produce
complete furniture suites. This field is the first to be ex-
ploited because timber shortage is limiting production.

Given a satisfactory development, there is a good possibil-
ity that a prefabricated parts export can be built up from
Britain to those countries which are without adequate wood
machining facilities. However, one limiting factor would
be the shipping cost for, being non-fibrous, Castwood is
heavier than natural timber.

To date, no details have been offered either as to its chem-
ical composition or technique of manufacture, though in-
dependent and unbiased industrial and chemical experts are
being kept informed of developments. The British furni-
ture industry is, for example, being given ample facilities
for investigation and will shortly receive a progress report
from Dr. W. D. Douglas, of Harris Lebus, Ltd. END

Novel Playing Cards Have
Plastics Coating-

ADD UP ALL the poker, gin rummy, cassino, 21 and
patience addicts in the United States plying their
pastime or trade in homes, clubs, trains and back bar-rooms,
and it is easy to see why we consume 77,000,000 decks of
cards every year besides another 25,000,000 for export.
Yet the industry has been sadly lacking in imagination,
according to the sponsors of a new four-color deck just put
on the market, for, they say, the United States in the only
country in the world which hasn't had such a one. Forcolar
Playing Cards, produced and distributed by Forcolar, Inc.,
of New York, have the conventional black for spades and
red for hearts, but the diamond suit is printed in yellow
and the clubs in green an obvious bid for the Irish vote.
And they are all acetate-coated so that they can be easily
cleaned and have a longer life than paper cards. Two decks,
packaged in a suede-finished box, retail for from $1.59 to
$1.69.

Although the additional two colors are naturally the main
promotion feature of the deck, the freshly designed symbols
are also stressed, and the plastics coating comes in for hon-
orable mention in the company's attractive brochure. No
extravagant claims are made for the coating simply that it
makes for easy cleaning with a damp cloth, and that it makes
the cards "last longer."

The initial exploitation took place in New York, where

Startling innovation in playing cards the
addition of two more colors to conventional
two-color deck promises to have popularity.
Plastics coating is another feature of new
deck, offering ease in cleaning and longer life

the deck was featured in the stationery department of Saks-
34th Street. Sales response was reported as excellent. The
store was given an exclusive for two weeks. The same
procedure was then followed in 56 cities east of the Missis-
sippi one department store in each city being given an
exclusive for the same period, and an additional two weeks
if it agreed to place another ad in the local newspapers.
Country-wide promotion was to follow.

The inventor of the new deck is Walter W. Artzt, who
claims he got the inspiration for it while sitting in as kib-
itzer on a bridge game. When one of the players mistook
a nine of diamonds for a nine of hearts, a row such as only
embattled bridge players are capable of, took place. That
started Mr. Artzt thinking, and the "bullet-proof" four-
color deck is the result. END

Filled with a light mineral oil, acrylic lens enlarges television images from two to
tour times, depending on distance at which it is mounted from screen. Oil filer
reduces weight of lens, increases amount of fight transmitted and clarity of image.
Total weight of new fens is about 20 pounds. Two similar types are now on market

THE EXCELLENT optical properties of acrylic plas-
tics are utilized in a lens which the Tube Department
of the Radio Corporation of America, Harrison, New Jer-
sey, has just put on the market to magnify the image on
television screens. Formed of clear Plexiglas and filled
with a light mineral oil of the same index of refraction, the
lens has an optical aperture of 12" X 15". It measures
14j/" high by \7 l /2 tr wide, with a maximum thickness of
3J4", and weighs about 20 Ib.

Magnifies Two to Four Times

Convex in front and planar behind, it enlarges the image
received on 7" or 10" television picture tubes, to the ap-
proximate equivalent of those produced by a 15" picture
tube.

The magnification depends on the distance at which the
lens is mounted from the screen, which is not critical. En-
largement ranges from two to four times as the lens dis-
tance increases from 4" to 10". There is a loss of viewing
angle with increased magnification and, conversely, a wider
viewing angle which would then entail a loss of magnifica-
tion.

The liquid-filled lens, it is said, weighs much less than an
all-glass or all-plastics lens would, while having the same
degree of magnification and transmitting a clearer, brighter
image.

It is also more economical, allowing a suggested retail
price of $59.50.

When used on a table or platform, the lens is fastened
by means of detachable legs, with bolts and nuts. It may
also be suspended from the ceiling by sufficiently strong
wire.

Avoid Locating Near Heat

Dealers are cautioned to avoid locating the lens in direct
sunlight or near heating fixtures a warning they are to
pass on to the consumer. Instructions are also given to wash
the lens occasionally with mild soap and water or a glass
cleaner. To avoid scratching the surface, a soft cheese
cloth or, better still, absorbent cotton is recommended. It
is also pointed out that after washing it is desirable to coat
the lens with a thin film of hard wax such as is used in
finishing automobile bodies.

Research on the acrylic lens was carried out by the Plas-
tics Engineering Section of the RCA Tube Department
located in Camden, New Jersey. The department is headed
by Ray Beshgetoor.

A similar type of Plcxiglas-fi\\ed lens for the same pur-
pose has also been put on the market at $59.95 by Electrovox
Company, Orange, New Jersey. Called the Walco Tele-
Vue-Lens, it is fabricated fpr Electrovox by E. L. Cournancl
& Company, New York. END

Available in a wide range of colors, Goodyear calendered vinyl flooring material is claimed to outwear rubber and linoleum

Better Wearing- Qualities with
Calendered Vinyl Floorings

SEVERAL YEARS of development on a new type
flooring material which should outwear the best
grades of linoleum and rubber, and at the same time offer as
much resiliency as rubber, has culminated in Akron. As a
result, the Chemical Products Division of The Goodyear
Tire & Rubber Co. has introduced a calendered vinyl floor-
ing material in a wide range of solid and marbleized colors.

The company's development laboratory claims the prod-
uct is highly stain-, scar- and flame-resistant; and from
demonstrations conducted before a group of 75 of the na-
tion's leading flooring distributors, the new material offers
great possibilities not only as a floor covering, but also for
sink drain boards, cabinet tops, work tables, and as wains-
cotting.

The fact that the company has announced its products as
a "calendered" material is an innovation within the indus-
try, as conventional processing up to this time has neces-
sitated what is called a "press cure." Needless to say, a
calendering process has infinite possibilities for high speed
volume production and Goodyear, knowing this, is reluctant
to discuss its production secrets.

The material, immediately available through distributors
and dealers in most of the nation's larger cities, is available
in three thicknesses, %2, VLO %z". Colors are two tone

A calendered vinyl flooring material has
been developed which is claimed to outwear
the best grades of linoleum and rubber,
yet offers the same resiliency as rubber

gray, two tone blue, green with white marbleization, terra
cotta with white marbleization, dark brown with gold mar-
bleization, black with white marbleization, cream with dark
brown marbleization, plain black, plain cream and terra
cotta red.

The material is available to distributors and dealers in
continuous lengths, 36J4" wide; tiling and decorative de-
signs being custom processed by the individual installers.

Dr. R. P. Dinsmore, vice president in charge of research
and development, describes the new product as a homogene-
ous thermoplastic mixture of vinyl resins, plasticizers, stabi-
lizers, pigments and colors. A vinyl resin, made from
acetylene gas and hydrogen chloride and utilizing a special
catalytic process developed by Goodyear at its subsidiary,
the Pathfinder Chemical Corp. at Niagara Falls, is the basis

tor the flooring material. Resins are shipped to Akron for
:he flooring production operations.

^ Development .work with vinyl resins was started by
Soodyear some four years ago, Dr. Dinsmore explained,
ind the company's initial findings made it apparent that a
sheet stock would be ideal for use in flooring because of its
:oughness, resistance to wear, resistance to oils, greases,
solvents, and because of its general durability.

Laboratory abrasion tests and actual wear tests on experi-
nental installations have shown the new vinyl material has
ipproximately twice the resistance to wear as the best
grades of linoleum or rubber flooring. For this reason, Dr.
Dinsmore said, it is possible to use thinner gauges; Me"
naterial being sufficient for normal floor service in contrast
:o heavier gauges in linoleum and rubber.

Yo Surface Accumulations

Test installations with all gauges have been made in
school libraries, on promenade decks of steamships, in rail-
-oad cars, offices and industrial plants, as well as in kitchens
is flooring and drainboard coverings. Due to the surface
lardness of the material (greater than linoleum at normal
oom temperatures and almost as flexible as rubber), the
naterial does not accumulate dirt, and its luster increases
,vith normal wear.

Spot tests with a large variety of commonly used house-
lold items of food, beverages, medicines, cosmetics, cleaning
igents and chemicals show no permanent staining, Dr.
Dinsmore continued. Cleaning is accomplished with any
)f the conventional detergents or abrasive cleansers. It
emains unaffected by animal, vegetable or mineral oils and
jreases even at elevated temperatures, and should it become
soiled with oil or grease, it can be cleaned easily with gaso-
ine. Only light coats of emulsion, liquid or paste waxes
ire recommended ; heavy coats only serve to collect grime
ind dirt to dull the natural high gloss of the material itself.

Spot stain tests were made with such items as blackberry
juice, lemon juice, mustard, catsup, vanilla extract, beet
uice, Coca Cola, beer, bourbon, whiskey, dark rum, tea,
:offee, Unguentine, mercurochrome, hydrogen peroxide,
ipstick, chlorox, washing soda, soap, ammonia, Energine,

VINYL, RUBBER, LINOLEUM FLOORING

Although vinyl flooring is more thermoplastic than most re-
silient floor coverings, installation process is about same

Windex, Drano, caustic soda, trisodium phosphate and
Carbona.

Smouldering cigarettes, which are always a problem in
public and office buildings because of the deep scars they
create, Dr. Dinsmore claims, have little effect on Good-
year's vinyl. While the temperature of a burning cigarette,
he said, is sufficiently high to soften the surface of the vinyl
flooring, imbedding ashes in the material, such stains can
be removed with steel wool and soap with little difficulty.

While rubber and linoleum when once set ablaze will
continue to burn, vinyl flooring will extinguish itself when
there is no supporting blaze. When certain materials be-
come available in sizeable quantities, Dinsmore added, the
flooring can be made completely fireproof.

Goodyear's vinyl does not support mildew, and has excel-
lent resistance to sunlight and weather. Accelerated

This design for a scale housing offers a fine ex-
ample of appealing functionalism in plastics which
is achieved without the exaggerated taper and flow-
ing curves affected by super-streamlined styling

Streamlining is a designing device which is
much overdone in modern products. Function
of part, esthetic appeal and cost are major
factors to be thought of, and streamlining
cannot be considered independently of them.
Various examples, both good and bad, are
cited to illustrate points made by authors

To Streamline

Bu WML* & Pt:olJ

General Electric Co.
and

Formerly of General Electric Co.

IN THE GUISE of modern design we now have vacuum
cleaners shaped like torpedoes, lighting fixtures that
resemble incendiary bombs, and streamlined ash trays that
threaten momentarily to zoom across the table and take off
for an upstairs bedroom. This is not a war-inspired motif
the trend has been in evidence for more than a decade.
The idea behind it is sound, but it has been either forgotten
or totally ignored in a wild scramble to "modernize" every-
thing furniture, household appliances, the most humble
toy and the most useless gadget.

Streamlining applied to moving objects is sound engi-
neering design. Based on the laws of physics, it is planned
to provide a shape that will move through air or fluid
with minimum resistance. Bjut^there is no justification
for streamlining an object That isn't going anywhere,
merely to give it an appearance of mobility ! The "tear-
drop" turret on the super-bomber (based "oh the same laws
of aerodynamics) makes sense the teardrop bay window
on your neighborhood filling station is just pure hokum.

Should plastics products be streamlined, and if so, when,
and how much? Before it is possible to present a case for
or against streamlining in plastics, it will be necessary to
provide a definition of modern design, especially as applied
to mass-manufactured products.

Good modern design is more than a matter of stream-
lining. It is a careful blending of the esthetic and the
practical, the beautiful and the functional. Its basic pur-
pose is to produce things that are easy to live with and to
use. Good modern design, if it is to be practical, must
not only be attractive and useful, but must lend itself to
economical manufacture by modern mass production
methods.

Three factors, therefore, must always enter into any
design consideration : cost, function or use, and esthetic
appeal. In a competitive market, cost always comes first.
Until the advent of modern design, function and esthetic
appeal were in a continuous struggle for second place which
usually ended in a draw. It remained for the modern de-
signer deliberately to set about integrating function and
esthetic appeal by basing beauty on the functional form.

The idea had often been unconsciously applied before;
most primitive furniture and tools, although made with
nothing but utility in mind, had a rude kind of beauty.
Nature has provided us with the perfect example of func-
tional beauty in the human body. And just as man has,
in various stages of his development, worn rings in his
nose and bells on his toes in an effort to be different and
"fashionable," he has, in the name of style, applied all
manner of superficial embellishments to the products he
has made. That he has not completely outgrown this ten
dency is evidenced by the current women's hats and the
male zoot suit and by the ridiculous examples of stream
lining now all around us.

It would appear, then, that streamlining is only justified

Molded elements in dashboard assembly are rightfully
streamlined to blend with exterior of the automobile

or Not to Streamline

A horrible example of streamlining con-
ceived by the designer to illustrate in-
tricate shape which not only lacks the
appeal of the familiar, completely func-
tional telephone set, but would be dif-
ficult to mold and would cost a great deal

A modified form of streamlining was re-
quired in designing of an electric steam
heater. Nevertheless, the designer has
maintained the appeal of simple functional-
ism by holding streamlining to a minimum

when it contributes to both esthetic appeal and function,
or when it facilitates manufacture. When the streamlining
of plastics products is considered, the latter factor may be
of utmost importance. An examination of molding tech-
niques reveals a number of reasons why a modified form
of streamlining is nearly always necessary.

Attractiveness in Funcfionolism

Functional beauty at low cost is made possible in plastics
by the nature of the materials and the manufacturing
methods employed. Intricate forms may often be repro-
duced in unlimited number, quickly and cheaply. Materials
can be formed with qualities as widely different as those
of wood, metal and glass by identical production methods.
In theory it is possible to mold almost any conceivable
shape; in practice there is a certain point where the
advantages to be gained by molding will be offset by ex-
cessive mold and finishing costs. The plastics designer is
always conscious that he must operate within certain fixed
limits imposed by the molds and presses and the men who
run them.

The conventional plastics molding is a thin-walled shell.
A minimum wall-thickness consistent with the desired
strength and stability makes for economy of both material
and labor. From a structural standpoint the ideal shape
for such a shell would be a section of a sphere. The spheri-
cal shape also molds with precision and ease. But an end-
less repetition of this shape would not only be monotonous,
it would not even follow the functional forms of most ob-
jects. The designer retains the structural advantages of
the spherical shape while following the flowing lines of the

product itself, by the use of broad curves and radii. These
radii also serve the very practical need of eliminating sharp
corners which are fragile and difficult to mold.

Taper is another factor which must always be considered.
For easy removal from the mold, the part must be some-
what smaller at the point where it touches the bottom of
the mold than it is at the mold opening. Although the taper
may be so slight that it is almost unnoticeable, every mold-
ing represents a section of a sphere, a pyramid or cone.
If so designed, it will not rub against the sides of the mold
when being removed. There must be no "undercuts" or
projections beyond this taper to wedge the piece in place
and hinder removal.

When the shape of the molded part is such that it must
be made not by one cavity but by two, the joint or "parting
line" where the two mold faces meet must also be taken
into consideration. Since this parting line must be re-
moved in a supplementary finishing operation, the part is
usually planned so that the joint occurs at a curved or
peaked area where it will be readily accessible and the cost
of the operation minimized.

To keep mold costs down, irregular curves must be
avoided, since they cannot be reproduced in the mold with-
out the use of templates or resorting to expensive machin-
ing methods. Raised motifs are easier to reproduce on
moldings than depressed ones, since they appear in reverse
in the mold cavity, and it is far easier to machine a design
in than it is to machine away the surrounding stock and
leave the design standing up. Large plane surfaces with
a uniformly good finish are extremely difficult to mold and

Measuring a Price Quotation

PURCHASERS of molded products often face a diffi-
cult problem in trying to measure the actual value of
the services offered by a molder. A sale is made by the
vendor offering the most benefits for the price asked ; often-
times he conceals or over-rates the values which he offers,
and in either case the buyer loses important values. Vendor
and buyer alike need to consider the important customer
benefits that are essential to the contract.

The basic consideration in any sales contract is the re-
sponsibility of the vendor. This responsibility includes not
only financial responsibility but also facilities and organiza-
tion. Obviously, the molder who accepts a substantial order
for tools and parts should show adequate financial responsi-
bility to carry out the project. An irresponsible operator
merely folds up when he quotes a price that he cannot live
with.

Less obvious to many is the importance of having ade-
quate facilities. Reserve capacity is very important to the
continuous production of molded parts. This means extra
presses and extra reserve power equipment. Facilities also
include adequate tool room equipment for mold repair work,
sufficient preforming and preheating apparatus, and ample
space and equipment to do a good job of finishing. Many
buyers have found that their molder had sold too many
molds for each press and was unable to give continuous
production of the quantity promised as the mold output.

A well-balanced and experienced organization that works
as a team is of fundamental importance. Experienced en-
gineers are needed to consider the product design and make
the proper decisions concerning its moldability. An under-
estimated job will ultimately cost the buyer more than it
costs the molder. Experienced engineers are needed to de-
sign the molds and plan the production methods; quality
control planning is based on experience and full considera-
tion of the potential hazards. Teamwork by sales, engineer-
ing, molding, finishing, purchasing and shipping are most
essential to quality molding service. Organization responsi-
bility also includes an adequate and cooperative labor supply.

Responsibility Should Not Be Divided

Divided responsibility is often a serious evil which proves
costly to the users of plastics. A fully responsible molder
will be willing to produce the tools that are needed for the
production requirements of the job. If the customer is
forced to purchase his own tools from a separate tool source,
the molder avoids the responsibility for their performance,
maintenance of accuracy and life. If he has underestimated
the job and has no responsibility for the mold, he will
merely say that the mold is no good and pass the responsi-
bility back to the customer.

A responsible molder wants to design and procure the
mold himself. His production costs are predicated on cer-
tain mold design features ; production continuity may de-
pend on the quality of steel in the various mold parts; the
quality and accuracy of the molded parts is a reflection of
the mold construction .quality. The buyer is entitled to ex-
pect the molder to assume full responsibility for the tools
needed for the production of the part in accordance with
the product drawing specification ; when the buyer furnishes
the tools, the molder's responsibility is limited to operat-
ing the mold and shipping pieces as produced.

In those cases where the customer undertakes to procure
the mold, it should be done on a basis which will not re-
lease the molder from his responsibility for the mold. In
this case the molder must design or approve the mold design,
check its quality at intervals during its construction, sample

by the diced-liller method. Pulled-back leather lining shows the liner of
pack5d "CCA," with sponge rubber covering for comfort. Channeling provides
the desired ventilation. (Right), diagrammatic cross-section of the helmet

THE LIVES of three and perhaps more pilots, and at
least $2,000,000 worth of experimental, irreplaceable
aircraft have been saved by some 20 low pressure molded
crash helmets utilizing Fiberglas cloth, Selectron polyester
resin and cellular cellulose acetate. These were produced
by or under the direction of the Aero-Medical Laboratories
of the Department of Aviation Medicine at the University
of Southern California.

Details of the many thrilling incidents in which the hel-
mets have played a part are not available for public re-
lease. This is because the limited number of helmets avail-
able are worn almost exclusively by test pilots who are fly-
ing experimental and highly secret aircraft. Any informa-
tion at all regarding crashes must necessarily include details
of performance which, interpreted by one familiar with
aeronautics, would supply vital pieces in the jigsaw puzzle
which a seeker of restricted information can put together
from isolated and seemingly unrelated facts.

However, acceptance of the helmets by major aircraft
companies is summed up in the words of a spokesman for
North American Aviation, Inglewood, California : "The
crash helmets are used 'by our test pilots, and they have
proved eminently satisfactory. The pilots wouldn't be with-
out them."

The development of the helmet goes back to the war, when
Dr. Charles F. Lombard, Associate Professor of Aviation
Medicine, University of Southern California, now in charge
of the Aero-Medical Laboratory there, was stationed at
Eglin Field, Florida, Army Air Forces proving ground for
all types of equipment. He was in charge of the Physiolog-
ical Test Section. Among the items submitted for test was

a crash helmet constructed from phenolic resin with a can
vas fabric base. Data secured from these tests emphasized
the need for development of the helmet, which is today
nearing the point when it can be placed in quantity produc-
tion.

The problem of head injury resulting from aircraft acci-
dents is probably as old as man's attempts to fly. Its first
occurrence in modern air travel as we know it was in Sep-
tember 1908, when Lt. Selfridge was in flight with Orville
Wright. His head hit a wooden upright, causing a skull
fracture, and he died a few hours later.

During the Spring of 1946, a project for the development
of an improved type of crash helmet was undertaken in the
Aero-Medical Laboratories, with funds contributed to the
University's Department of Aviation Medicine by six mem-
ber companies of the Aircraft Industries Association. In
direct charge of the program and engaged in much of the
research is Herman P. Roth, engineering consultant for
the Department. Assisting in the program have been Ben-

jamin Goulston, laboratory assistant, and Miss Ina DeCan,
advanced student in sculpture. Mrs. Martha Mill, expert
upholsterer for the Department of Aviation Medicine, has
been in charge of the trim and upholstering aspects of the
helmet development.

To understand the project, it is necessary to consider the
physiological and mechanical aspects of the problem. What
happens in a crash is that the head travels generally forward
and hits some other object. The impact may produce various
effects, such as lacerations of soft tissues, fractures of the
face and skull bones, and brain concussion. While there
are several phases to protection against injuries of this
type, we are concerned here only with protective headgear.

Desirability of improvement of this item has been accen-
tuated in the last few years by development of very high
speed aircraft, which has magnified the problem of buffeting
under some conditions. New problems have been created
relative to escape by ejection and protection of pilots against
high-speed airstreams.

Principal Objectives

Principal objectives in design of the protective headgear
were protection of the head against: (1) fracture of the
skull, through reduction and distribution of impact forces,
(2) brain concussion, through control of the rate of de-
celeration, (3) penetrating wounds due to flying fragments,
by use of impact and penetration resistant materials, (4)
harmful vibratory forces, by proper cushioning and use of
sound and vibration absorptive materials, (5) high en-
vironmental temperatures and radiant energy levels, by use
of radiant energy-reflective surfacing, thermal insulation
and (if required) forced cooling and, conversely, protec-
tion from extreme cold, (6) wind blast and flash burn effects
by suitable fit and anchorage, and by proper integration
with other protective gear, such as goggles and oxygen
mask.

Additional considerations were : ( 1 ) minimal interference
with communication, and its enhancement if possible, (2)
minimum practicable size, on account of wind blast forces
and problems of clearance within cockpit canopies, (3)
minimum practicable weight, to avoid fatigue when worn
for extended periods and to assure tolerable loading of
head-supporting muscles under high "g" forces, (4) smooth
exterior, to avoid damage to canopies, (5) adaptability to
varying head sizes and shapes, (6) avoidance of unneces-
sary interior fittings or projections, especially of a pene-
trating nature, (7) sanitation, (8) over-all comfort for any
necessary period of wear.

There is a great gap in the information available on the
physiological considerations of brain concussion and the
limits of tolerance of the human head under various condi-
tions of impact. Development of this information consti-
tutes the next portion of the research program which has
resulted in the present crash helmet. From the data avail-
able, however, it is obvious that a primary objective in its
'design should be provision of the best available means for
minimizing acceleration (or deceleration) of the head un-
der crash conditions, in addition to the widest possible distri-
bution of the decelerative forces over the entire area of
the head.

Plastics Satisfy Objectives

Plastics materials of various types are the only ma-
terials which would satisfy all these objectives at least in
part, especially in combining low weight with high strength.

Basic considerations in the design were: (1) the deci-
sion to integrate or incorporate headphones within the hel-
met shell, (2) allowance of YZ" spacing between head and
helmet shell for energy-absorbing lining, except in front
where from %" to one inch was allowed.

These considerations permitted establishment of an ex-
terior shape which practically covers the whole head with
the exception of the face. The shell terminates in front at
a point just high enough above the brows to allow use of
standard Air Corps goggles. It extends as far down in
back as possible without interference with head motion
within the optimum range necessary for scanning the sky.
Pockets were formed over the ears for accommodation of
standard Signal Corps earphones.

A standard AAF plaster head was used as a model and
Miss DeCan achieved a smooth and symmetrical outer shape
by use of modeling clay, maintaining the desired thickness
of lining in the designated areas as the first consideration.

Brandt Goldsworthy, Industrial Plastics Corporation,
Gardena, Calif., was called into consultation, and it was de-
cided to produce the helmet shells from Fiberglas cloth No.
ECC-162, laminated with Selectron No. 5003, a styrene
polyester resin. These were molded in female plaster molds,
from plaster forms taken from the clay modelings in three
sizes, by the low pressure bag process. All helmet shells
manufactured to date have been produced in these molds by
Industrial Plastics Corporation.

The shells were first made with six layers of Fiberglas,
but they were found to be excessively heavy and rigid. Cur-
rent models employ four layers of cloth, except over the
earphones where only two layers are used. The sacrifice

of strength in the lower area is compensated for by thick-
ness of the earphones, and flexibility in putting on and re-
moving the helmet is desirable.

The bare shell, without lining or fittings, weighs 15 oz.
Its overall width is 8ft", overall height 9J4", length 9J4".
The weight of the completed helmet is approximately 45 oz
at present, but current design developments promise to re-
duce this to less than 40 oz. Helmets are available in three
sizes head size of 7 or less, 7 to 7^, and 7yi or larger.

The average thickness of the four-ply laminate is ap-
proximately 0.06". Engineering tests of samples of similar
material, not in the helmet, show an ultimate tensile strength
of approximately 34,000 psi.

At about the time the shells were available, Northrop
Aircraft Company heard of the project, and asked for a
number of them for use in test flights of their XB-35 Fly-
ing Wing bomber. Since the date for testing was close,
Northrop completed the shells in their own upholstery de-
partment. Pieces of compressed foam rubber in suitable
thickness were enclosed in pockets of airplane cloth and
stitched into parallel ribs whose spacing, together with the
original thickness of the rubber, determined the ultimate
thickness of the pad and the degree of resiliency. Fitting
to individual heads was by trial and error. Edges of the
helmet were protected with a roll of sponge rubber, and
the whole lining was covered with chamois.

Experience with these Northrop helmets resulted in de-
velopment of a spring suspension device for holding the
earphones in place. These can be pushed back against the
shell when putting the helmet on or taking it off, and held
there with a pin. Release of the pin allows the earphones
to snap into place over the ears.

At this point, a new concept was injected into construc-
tion of the lining material. It was to use a non-resilient,
energy-absorptive material having a definite structure which
would be deformed or destroyed upon the application of
compressive forces, resulting in energy absorption without
the development of high restitutive forces. In other words,
this material would absorb the blow of the head against it,
and retard its deceleration by breaking down its structure.
There would then be no "kick-back," as is the case when a
resilient material such as rubber absorbs a blow.

Mr. Goldsworthy suggested the investigation of newly
available semi-rigid foamed plastics materials. From these,
DuPont's cellular cellulose acetate CCA was selected
as the most satisfactory. This material is available in
"board" form, and in varying densities. The one with the
lowest density was chosen about four or five Ib per cu ft.

This material reacts to compressive stress in an interest-
ing manner. Plotted in a stress-strain diagram, it behaves
as a resilient material until a compressive stress of about
90-100 psi is reached. Thereafter, considerable further
compression occurs without much corresponding increase in
compressive force. As compression proceeds to a thickness
of about 30 per cent to 40 per cent of the original, destruc-
tion of the cellular structure merges into a "packing" effect,
and the compressive force increment for unit compression
again increases.

Within the range of action wherein considerable com-
pression occurs without great increase in compressive force,
reduction of the compressive force is followed by very little
expansion of the material.' It is in this range that the ma-
terial functions primarily as a non-resilient energy-absorb-
ing material, and the energy dissipated is measured by the
average force applied, multiplied by the distance the ma-
terial is compressed.

A resilient material, on the other hand, would store up
energy during compression; the restoring force opposing
the compressive force would rise more or less proportionally
to the amount of compression ; the deceleration of the object
producing the compressive force would reach a peaked max-

imum at the point of greatest compression: and the object
would be accelerated in the reverse direction by the energy
stored in the resilient material.

The next development took place at North American
Aviation, under direction of the Aero-Medical Laboratories,
where helmets were individually fitted by carving out solid
blocks of CCA to the contour of the individual's head, al-
lowing space for a thin layer of sponge rubber for comfort
in wearing. Ventilating channels were provided with ven-
tilating holes drilled in the outer shell at several points.
This was also coated with gold foil to minimize radiant
energy absorption in a hot sun under a transparent canopy.

This method resulted in a helmet that was extremely
satisfactory from the standpoint of fit, but very expensive
and not adapted to quantity production. Consolidated- Yul-
tee also produced two helmets by this method.

Dicing Method

The third method was to chop or dice the CCA into
small cubes and mix them with a binder. The resultant
mixture was packed between the helmet shell and a cast-
ing of the head which had been properly positioned within
the shell. A thermosetting synthetic elastomer known as
Superlastic, mixed with ammonium carbonate as a foaming
agent, was used as the binder. The whole was cured in an
oven at approximately 275 F. Several helmets were made
in the Aero-Medical Laboratories for the Sperry Gyroscope
Co., and Douglas Aircraft Co. also used this process to pro-
duce helmets that provided an individualized fit at rc;i>oii-
able cost. However, the weight factor and relative cumber-
someness of the process have led to further research.

The current method, which seems to offer production
possibilities, is to channel the CCA blocks almost through
their thickness with saw cuts in a waffle pattern. Onto this
is molded foam rubber by a process developed by Barton 1 1.
Thompson of Molded Products, Hollywood, a leading rubber
and plastics technologist for the motion picture studios.

This waffled CCA and rubber material is flexible and
allows the CCA to yield under impact forces. As now ap-
plied in the helmet shell, blocks of the waffle-cut CCA, of
thickness appropriate to their location, are used to line the
entire crown section of the shell. A plaster replica of the
pilot's head is positioned so that there is about J4" between
it and the CCA, and the foamed rubber is flowed into the
remaining space and into the saw-cut slots in the CCA.

Channels for ventilation and earphone wires are cut after
molding. Separate molded pads of foam rubber are used to
position the earphones, which are retained in pockets
molded in the rubber. Only the motor units of the ear-
phones are used, the cases being eliminated to save weight.

The whole interior is covered with suede leather with
the smooth side out, and the edge is protected with a roll of
foam rubber covered with suede.

Further experiments are under way to develop a method
of suspending the lining, possibly by a sling, which will
eliminate the necessity for individual contouring. This is
somewhat doubtful of success, however, since fit is an im-
portant part of the performance of the headgear.

Additional work is also being done to develop suitable
surfacing techniques. Gold leaf is very satisfactory as a
reflecting agent, but it is not durable and soon scuffs off.
Other materials that have been used are paint impregnated
with powdered metal, and plain white lacquer.

The Aero-Medical Laboratories of the University of
Southern California feel this project is ready for applica-
tion to a standard commercial set-up for production and
distribution. While further improvements will come, the
helmet now available justifies itself on performance, and
techniques as developed in the latest laboratory processes are
reasonable in cost, although marked savings can be realized
as production is developed. END

This feen-age member of the plastics family
has a wide range of uses in both sheet and
molded form. Availability of large size sheets,
excellent optical properties, dimensional
stability, and impact strength and weather
resistance lead to such diverse applications
as aircraft and vending machine enclosures,
machine guards and light shields, outdoor
signs and letters. Edge-lighting effects
typify acrylic's functional, decorative uses

ACRYLIC RESIN plastics have a combination of func-
tional and decorative values that has led to their use
in a wide variety of fields, ranging from costume jewelry to
modern architecture. Between these extremes lie such
divergent applications as signs, aircraft enclosures, lighting
fixtures, merchandising aids, automobile parts, safety appli-
ances, home furnishings and accessories, and hospital equip-
ment, with scores of separate uses in each category.

Introduced first in sheet form, acrylic resins are now also
available in rods and molding powders in a variety of sizes,
forms and grades, and in a full range of transparent, trans-
lucent and opaque colors. One of their major advantages is
the relatively large size of sheets up to 67" X 79" for
which casting methods have been developed, with thick-
nesses ranging from 1/16" to 2" for polished and up to 3"
for unpolished sheets.

It was their combination of properties which made these
sheets a welcome addition to existing materials in 1935.
They were not only as clear as fine optical glass and
unaffected by strong sunlight or extremes of weather, but
they were also light in weight, had high impact strength and
dimensional stability, were resistant to the action of most
chemicals, and were excellent electrical insulators.

In addition, being thermoplastic, they could be formed to
almost any desired shape by being heated to a pliable state.

Finally, the new material could be machined in the same
way as wood or soft metal. The advantages of this sheet
plastics in many applications led to a desire on the part of
molders for an acrylic resin molding powder that would
impart the same properties, and these were introduced three
years after the cast sheets.

The various properties of acrylic resins are best under-
stood through a description of how they are used in diverse
applications.

Advantageous in Signs

In signs, acrylic sheets are advantageous because of their
general optical properties, the ease with which they may be
lettered, their resistance to weathering and the facility with
which they may be formed. Their high degree of trans-
parency, which transmits all colors of the visible spectrum
with 92 per cent efficiency, carries with it a number of inter-
esting features. One of these is "light-piping," which has
resulted in the design of "edge-lighted" signs whose lettered
messages are sharply illuminated by light that is not visible
elsewhere in the plastics sheet.

In such signs, the light source is concealed at one edge of
the sheet. The light-piping phenomenon is due to the abil-
ity of acrylics to transmit light rays from one edge of a
sheet through to the opposite edge, by repeated reflections
between the polished surfaces. In travelling through the
sheet the light becomes visible only where the surface is
"broken" by carving, engraving, sanding or painting. In
edge-lighted signs, the letters or designs painted, etched or
engraved into the back of the acrylic sheet provide this
necessary interruption of the course of light, and therefore
are illuminated as the light escapes from the sheet at the
point of interruption. Edge-lighted signs are especially
valuable for attracting the attention of customers to mer-
chandise in department stores and specialty shops.

Many other types of signs utilize acrylic sheet material.

Block letters cut from thick translucent sheets and lighted
from behind offer advantages in light weight and resistance
to prolonged outdoor exposure. Outdoor "spectaculars" are
constructed by heat-forming large sheets to illustrate the
advertiser's product ; on theatre marquees, fabricated or
molded letters are silhouetted against a lighted translucent
background with excellent results. The use of colored
material in sign applications is extensive because of the
pleasing effects obtained with the deep, rich, warm colors
available.

The formability, strength and optical properties of acrylic
sheets were dramatically used during the war years in the
transparent bomber noses, gun turrets, navigator's astro-
domes and other enclosures on vvarplanes which required a
lightweight, weather- and impact-resistant, formable ma-
terial through which perfect vision was obtainable. The
fabricating techniques developed for these products estab-
lished the basic methods which are used in fabricating
acrylic plastics today. The acrylics have continued to be the
standard plastics material employed by the aircraft industry
for transparent enclosures. They have also been used for
enclosures on automatic vending machines, replacing glass
and even metal in some cases.

The decorative possibilities of flat acrylic sheets were
ingeniously exploited in perhaps the largest table ever fash-
ioned from that material, by the New Horizons furniture
department of James McCreery & Company, New York.
Made from a special sheet of clear Plexiglas 67" X 29" X
}<;", the table is brought up to 72" length by an opaque
black border of the same material 3" wide. This, together
with a black 2>4" apron, makes an effective contrast with
the large clear sheet.

Designed with cut-out curves instead of square corners,
the table may be extended two feet on each end and given a
rectangular form by two small console tables which fit into
the corners. These auxiliary tables, which may also be used

FLASTICS

"Lucite's" light-transmission qualities are used to advantage in dial of instrument which measures wind velocity and direction

separately as living room desk and dining room serving
table, have three small sections of black Plexiglas inlaid in
their tops.

Another novel feature of the large table is a 36" ring, 4"
deep and y 2 " thick, under the center of the table. Suspended
from it is a shallow curved disc to hold a floral or other
centerpiece, which gains a certain charm when seen
through the acrylic top.

Designed by Mary Luscher, director, and James Mitten,
associate director of the store's decorating staff, the set is
priced at $2,000. It was fabricated by E. L. Cournand &
Co., New York. Fitting of the long joints between the
large sheet and the border, as well as between the latter
and apron, was accomplished by a plywood fixture with
coiled springs which applied a pressure of some 10 to 20 psi
after the parts were bonded with an acrylic solvent cement.

Widely Used in Lighting Fixtures

Acrylic plastics have more recently come into wide use in
lighting fixtures, where their ability to transmit or diffuse a
maximum amount of illumination is of great value. As
curved shields covering fluorescent tubes, or as panels set
flush with ceilings and walls over incandescent or fluores-
cent lighting sources, they offer advantages in modern
illumination systems. For interior lighting, curved or flat
white translucent sheets are generally used. An important
exterior lighting application is expected to develop from the
use of formed clear transparent street-lighting globes, whose
shatter-resistance will cut replacement costs on such fixtures
to a minimum.

Additional uses in the lighting field include edge-lighted
wall murals that combine auxiliary illumination with dec-
orative values, and table lamp shades.

Because they can be formed and machined without difficul-
ty, and because of their great transparency and natural
beauty, the acrylics have also found application in the field
of merchandising aids, where these properties promote the

effective presentation of retail goods. Counter display cases
can be formed as one-piece units, or separate acrylic sections
can be cemented in permanently strong, invisible bonds, re-
sulting in cases that give 100 per cent visibility of contents.
The sparkling transparent beauty of the cases themselves
provides a striking setting for the items displayed in them,
and attracts customers to the point of sale.

Another growing merchandising-aids application is in
large showcases where front, rear, top and side sections are
formed of the crystal-clear material. One important ad-
vantage acrylics have here is that scratches, which are
suffered by all showcase materials in the course of normal
store operations, may be polished or buffed out, whereas
other materials would need to be replaced.

Additional uses in this field include small transparent
packages molded from acrylic powders for such items as
razors, pen and pencil sets, perfumes, and display racks for
shoes, hats, silverware and lingerie, and storage trays for
back-of-the-counter display of soft goods. In all these
applications, the light weight of the acrylic material, which
is less than half as heavy as glass, provides ease of handling
by store personnel.

Effective in Home Furnishings

Designers in the home furnishings and personal acces-
sories fields have worked effectively with acrylics. The
range of products which utilize their decorative qualities and
permanent attractiveness is limited only by the imagination
of the craftsman.

The excellent moldability of acrylic powders, which are
produced in various grades for injection and compression
molding and extrusion, and in a wide range of colors, has
resulted in their use in applications calling for a large num-
ber of identical parts. Such moldings retain the properties
of acrylic sheet material, and are distinguished for their
light weight, excellent electrical properties and high dimen-
sional stability. Acrylic moldings come from the mold with
a high polish, ready for use without further finishing.

Consumer's Markets

Head (foreground) and body of new and improved musical fife made from General Electric laminated tubing

A musical fife, fabricated from laminated phenolic tubing, has fingering arrangement
which is similar to that of the fiufe. This new instrument has market possibilities
as a beginning instrument for children who will want to study the fiufe later on

LAMINATED PHENOLIC, long the workhorse of
plastics materials, has at last made its appearance in a
product that is seen and used by the general public. A new
and improved musical fife has recently been introduced by
Leonard O. Merrill of Jamaica Plain, Massachusetts, which
is fabricated from laminated tubing made by General Elec-
tric Company, Plastics Division, Pittsfield, Mass.

Known as the Boehmbore fife in B flat, the new instru-
ment is said to respond readily throughout a wide range of
tones. According to George P. Madsen, flutist for the
Boston Symphony Orchestra, the tone quality of the fife is
flute-like, and the intervals on the instrument perfectly in
tune. Resistant to corrosion, humidity, and sudden tempera-
ture changes, the new instrument is also featured by its light
weight, toughness and durability, making it ideal for fife and
drum corps and similar organizations. Because its fingering
is so close to that of a conventional flute, the new fife is said
to be excellent for starting off the instruction of children
who might later take up the flute.

Construction of Fife

The fife is 15" long and ^" in diameter. It consists of
two main sections: the head and the body. The head is
reamed to a slight taper to make the octaves come in tune,
and finger holes are accurately drilled in the body of the
instrument. The fife's carefully constructed blowing aper-

ture is centered on a piece of laminated tubing 2" long and
54" in diameter which is slipped on the head of the fife and
cemented in place. It is then spun to finish.

Mr. Merrill has also made an experimental chromatic fife
out of G-E laminated plastics tubing and sheet stock. On
this instrument, the notes are said to be fingered exactly as
they are fingered on the best Boehm piccolo, but the mechan-
ism has been greatly simplified. END

Measuring a Price Quotation

(Continued from page 32)

designs the product and selects the material for much ex-
perience is needed to evaluate the materials and product
designs properly. Customers must be wary of the molder
who offers only one type of material or method. His eager-
ness to obtain an order may result in material or product
claims that result in loss. Marginal applications must be
evaluated by unprejudiced engineers who are prepared to
produce the part from any material or method.

The Request For Quotation Form illustrated was pre-
pared to list the factors that are important to material selec-
tion and quotation preparation. The buyer's engineers
should fill in this form when an engineering conference is
not indicated so that the molder may present the most eco-
nomical proposal and be better prepared to suggest alternate
materials that may offer greater value. The submission of
models is most helpful for best price and good engineering.

The lowest price may not offer the greatest value. The
following comparative quotations as submitted by two com-
peting molders will illustrate the importance of a carefully
prepared quotation.

Molder A

Part Drawing Name and Number: Cover Plate K-64923.

Mold: 6 Cavity Injection Mold $1400.00.

Special Fixtures: Inspection Gauge $175.00.

Mold Delivery: Approximately 14 weeks after receipt
of complete instructions.

Material: Ethyl cellulose.

Color: Black.

Estimated weekly mold capacity: 72,000 pieces.

Inserts: None required. ,

Mold Setup Charge: $25.00.

Price of Pieces Per Hundred: $14.75.

Remarks: Customer will burr center hole during assem-
bly. Molder will burr 9 3 /s" I.D. holes, remove two
gates, buff molded piece completely and wrap each
piece separately. Tolerance on the 3.00 + .000
.002 dimension must be increased to .000 .010.
Sinks may show between the holes over the ribs.

Molder B

Part Drawing Name and Number: Cover Plate K-64923.

Mold: $1325.00.

Mold Delivery: 15 weeks.

Material: Ethyl cellulose.

Price of Pieces Per Hundred: $6.80.

When questioned, Molder B advised that his proposal
covered the supplying of molded pieces only with gates
broken off and flash in the holes as they come from the
press. When he requoted to give the pieces finished as speci-
fied in the print, he submitted a higher price than Molder A
did. If the difference between the original pair of quota-
tions seems exaggerated, I can only say that they represent
the actual experience of one end-user.

The responsible and experienced molder refuses to quote
on products that show impossible dimensional tolerances
and unmoldable sections. He takes exception to these de-
tails in making his quotation. He details the finishing op-
erations that are included in his proposal so that the cus-
tomer may know exactly what he is buying. The mold size,
type and production capacity must be plainly shown to en-
able the buyer to determine the true value of the proposed
mold investment. Extra finishing and inspection fixtures
included in the mold cost are an index of quality planning
and future production satisfaction.

Good quotations will also include data concerning insert
supply and responsibility, cost of color changes, alternate
materials that should be considered, mold delivery time,
mold set-up charge, quantity variables, and a full statement
concerning the tool ownership, tool maintenance responsi-
bility, and all other responsibilities assumed or excepted by

the molder. It is hoped that the S.P.I. Standard Terms sug-
gested by the Accounting Committee will be adopted by the
entire industry so that "fine print" exceptions can have no
effect on the actual prices shown in the several quotations.

Many molded products require special packing and han-
dling that may not be shown in the quotation, and this con-
sideration may make a substantial price consideration. Re-
sponsible molders will indicate the type of packing for ship-
ment for those jobs which require special consideration.

In all cases, the buyer will get what he pays for, and
he must be able to get the facts from the quotation sub-
mitted if he is to understand the price differentials and
select the proposal which offers the most value for tin-
price asked. END

American Families USE Plastics

(Continued from page 13)

records made from a vinyl compound. The records are a
source of perpetual enjoyment for the children, which is
heightened by the freedom which the non-breakability of
the records affords.

Among the miscellaneous useful objects in the house
where plastics serve are a number of clothes hangers fabri-
cated from acetate and acrylic rod, the case for the furnace
thermostat regulator, the case on the telephone list-finder,
and a set of hand-decorated coasters made of acetate sheet.

Peter's workshop does not yield many plastics applica-
tions. In addition to the molded thermosetting case for his
Moto-Tool hand grinder, he has a "Plastic Eye" flashlight.
The knobs on his Walker-Turner drill press are plastics,
and on the reflector of the guide light on the router is a plate
bearing the legend "Hot When Light Is On 1" So many
people burned themselves on this innocent-appearing object
that Peter engraved the sign on a piece of Spauldite while
he was working at LaMoree's.

The family automobile is an infertile field for plastics
research. Peter has staunchly resisted high prices and is
still driving the '35 De Soto he acquired during the war.
About the only evidence of use of plastics materials here,
with the exception of standard ignition parts, gears, insula-
tors, etc., is in the knobs on the dash. These are faced with
a transparent material which appears to be acetate, engraved
and filled from the back to designate the function of the part.

The Peter Conway's don't make a fetish of plastics. In
fact, they make little of them. They take them as they come,
and make the best possible use of them, as they do of every-
thing else that enters their lives. But think back a moment
on their living arrangements, their children's eating and
playing, their home decoration and hobbies. Take away the
plastics and what an enormous hole there would be !

THE FAMILY OF LOUIS E. SASS. JR.
OF DES PLAINES. ILLINOIS

The home of Louis E. Sass, Jr., near Des Plaines, Illinois,
in the rich farming district northwest of Chicago, reflects
the wealth that food demands have brought to the farmer.

In a modern six-room house, young Mr. Sass and his
attractive wife are kept busy with the demands that go along
with a well equipped farmstead and a two-year-old-baby.

The farmer's family is no longer remote from the taste*
and fads of the big city. Frequent trips to Des Plaines and
occasional jaunts to Chicago, plus frequent reference to the
mail order catalogs, keep the Sasses in touch with every-
thing that's new.

We visited them during Christmas time, anil the living
room, for instance, showed how widely plastics have be-
come accepted in Christmas tree ornaments and other sea-
sonal decorations; the toys under the tree also evidenced
general acceptance. In addition, there was a plastics-coati <1

suitcase (the Christmas present for one member of the
family), and a desk chair covered in the same material.

The dining room showed more influence from the industry
by its plastics-coated chair seats, and a set of table knives
and forks with cast phenolic handles.

The bathroom contained numerous plastics products, all
of which represented items of utility or necessity. The com-
plete list was composed of shower and window curtains of
pliable film, a polystyrene drinking glass, the usual tooth
brushes and holders, a few cosmetic containers, an electric
shaver with urea shell casing, and a nitrate sheet coated
toilet seat.

In the nursery there were a dozen sheet film bibs for the
baby and a clothes hamper with coated top.

Plastics were represented in the kitchen by the handles
on the entire set of silverware,' handles on all utensils, cookie
cutters in various shapes and patterns, the baby's cup and
plate set, refrigerator dish covers and bags, and a clock case.

Among the extras found about the house and in the base-
ment were phonograph records, a plastics spiral binding on
a phonograph record album, an umbrella handle, a bowling
ball, deep freeze storage bags, soap dishes, clothes hooks,
and the thermostat casings.

Mrs. Sass said that they had also used plastics strip
edging on the step nosing of the rear stairway which led
one-half flight down to the ground entrance and another
half-flight down to the basement. The edging was used as
a war measure when the metal edging was unavailable. The
results of using such material were disappointing. It did
not wear well ; it cracked with changes in the weather ; and
it did not seem to be as safe for good footing as metal strips
are.

The garage and barn of the farm did not contain one
article made of plastics or with plastics parts.

Opinions from the junior Sasses and from Mr. and Mrs.
Sass, Sr., who were also interviewed, were not particularly
flattering. The wives were surprised to learn that many of
their most used items were made of plastics. They did not
realize that plastics offered any special features pertinent to
their own home life. All utensils found in this survey were
originally purchased because of necessity or unavailability
of conventional items in the same line.

The typical attitude of the men was : "Plastics seem to be
a great thing, but we don't know anything about them.
Probably five years from now practically everything will be
made of plastics." END

One Mold Makes
Two Cabinets

Plastics product can be redesigned at
comparatively little extra cost by
making modifications in existing mold

WHEN DRASTIC redesign of a product is not neces-
sary, it is sometimes possible to modify the existing
mold sufficiently to make an essentially new design, and at
comparatively little extra cost. A case in point is offered by
the two Emerson radio cabinets illustrated here, both of
which were designed by Van Doren, Nowland & Schlader-
mundt, New York, and which were produced from the same
basic mold.

Both models fall within Emerson's popular price lines.
When the earlier one (Model 522) had about exhausted its
market, the company called on the designers to modify it so
that it would look like, and to all intents be, a different
design. This was effected by cutting away the whole cen-
tral portion and right side of the original mold. Retaining
the upper and lower horizontal bands, the designers extend-
ed them around to one side (the right side on the photo-
graph), creating a more unified form. They also took care
of the radio company's trade mark by cutting out the mold
at the left side, bringing the Emerson emblem up flush with
the grille, which at the same time provides an attractive
plane.

A simple metal screen element was substituted for the
original front. It is assembled to the instrument from the
rear and attached by studs. The rectangular dial was
replaced by a circular one, thus repeating the form of the
control knobs. This dial is press fit into the screen.

Model 522 was thus converted to Model 543 and given a
new lease on life. END

Van Doren, Nowland & Schladermundt made a
simple change in their design of mold used
to produce Emerson "Model 522" (below).
"Model 543" (left) was the resulting radio

<I In the same way, each businessman, with full
knowledge of the supply exceeding the demand,
believes in his own ability to survive when others
fail.

<I It is such confidence in himself, such hope in
his luck and such faith in the American profit
system, that has left America the leader of the
world.

* INTEREST RATES HIGHER

<J This observer has previously discussed the
basic, long-term up trend in interest rates. In
the past six months this trend has achieved sig-
nificant reality. Those powerful, natural eco-
nomic forces, working for higher earning power
for invested capital, have affected the policies of
many of the banks with a relative shortage of
money.

<I It is going to become increasingly hard for
companies to finance themselves as easily as in the
past. Should inflation continue, controls are
likely to be enacted by the government to even
further shorten the supply of cash. This reversal
of a 15-year trend will have its effect on the plas-
tics industry, which acquires in 1948 many mil-
lions of dollars. The rate of expansion, already
noticeably slower, will settle at a cautious level.

* OUT ON A LIMB

<I Last year at this time, the plastics industry
was crying the blues; business in general was
warning of an impending recession. Today, all
business men see only good months ahead. That,
in itself, should be a warning of what lies ahead
for us.

I Another warning: When commodity prices
and wholesale prices soar to fantastic limits, a
bump is usually due. In 1920, wholesale prices hit
a high of 153.5 (based on 100 average for 1923),
but bounced to a low of 96 a few months later ;
while in November 1947 they hit a new high of
158.3.

<I This column predicts, and this is the first time,
that in 1948 they will hit a low of at least 125.
With the collapse, consumer prices will be
dragged down.

<I The economists for both labor and manage-
ment can prove anything they want while "fig-
ures don't lie, liars can figure." From one view-
point, the worker is certainly in a poorer position
that he was three years ago, or even last year.
But he is still better off than he was before the
war. Now, his habits and standards of living
cost more. Perhaps the answer is to return to a
simpler form of living, cut income taxes and
work longer hours for straight time. It's brutal,
but the warning: "Work harder, longer and more
effectively," has been repeated so often by wise
men that maybe it will catch hold. It's the only
thing that hasn't yet been tried.

* PROFIT SHARING

I Dean C. Canby Balderston of the Wharton

PLASTICS

School of Finance and Commerce accepts that
under normal conditions, profit sharing is good
business, but he concludes that, in unusual times,
profit sharing for wage earners is not so effec-
tive and is not a true financial incentive to in-
crease employee efficiency.

<I There are many plans which operate company-
wide most effectively. Lincoln Electric offers an
outstanding experiment in successful profit shar-
ing. For any plan to yield really extra, profit to a
company it must have a theme, a promotion, a
constant challenge always supporting it. James F.
Lincoln is the promoter behind his plan. His
character, his philosophy, his color give the plan
the employee promotion that is necessary to make
a shop work in April, as it does in December. Not
many companies are as completely dominated by
such a colorful figure; not many companies as
big as his are owned by so few people. Unless a
company has someone who can supply driving
power as a full time job, to make a profit-sharing
plan work, there may be difficulties. It's harder
to discontinue a profit-sharing plan than it is to
instigate one.

* A STUDY IN FINE PRINT

<I Probably one out of ten purchasers of plastics
has read the Terms and Condition of Sale marked
in fine print on price sheets or acknowledgement
forms. They vary for each company. Although
complete standardization is impossible, some defi-
nition of trade practice for each class of com-
pany could possibly clarify the intent of the fine
print for the individual purchaser. This study
might be considered by some plastics organization
for material suppliers and for molders. The Na-
tional Industrial Conference Board will soon is-
sue the results of a study it has conducted along
these lines for all business.

* HERE WE GO AGAIN

I As this column goes to press, new wage nego-
tiations are under way. The fierceness with
which hikes will be sought is indicated by the
keynote sounded by Reuther, of the Automobile
Workers' Union : "We will demand and win."
This can only result in further price rises, unless
the counter-move by C. E. Wilson of the General
Electric Company and others to reduce the cost
of popular merchandise lines to the public, is ef-
fective in some broader way. And so conflicts
arise once more.

<jj Wages will be determined by a complex set of
conditions, the most important of which is the
supply of and demand for workers. No artificial
pegging f wages can long exist in a free econ-
omy.

<J Some labor demands have resulted in just an ]
artificial rate which lasted for the short period
until prices adjusted themselves accordingly. It is
indicated that gradually wages and prices will fall
in line by a natural process, and not from our
based on threats and coercion. END

For molded acrylic parts of

exceptional heat stability

It pays to use PLEXIGLAS "V." This newest
member of the Rohm & Haas family of acrylic
molding powders has the extremely high A.S.T.M.
heat distortion temperature of 197.6F (92C)
shrinkage after 48 hours at 212F (100 3 C) is less
than 10 mils per inch.

With these features, which assure extraordinary
stability under high-temperature service condi-
tions, PLEXIGLAS "V" combines clarity and bril-
liance surpassing any previous molding powder to
bear this famous name. In addition, PLEXIGLAS

"V" flows at notably low temperatures for a
heat-resistant material resulting in molding
speed and economy.

Of course, PLEXIGLAS "V" retains the familiar
features that have made other Rohm & Haas
members of this acrylic resin group a leading
choice with the automotive industry high impact

JVew Transfer

Print Method

Developed

Packaging seen as ma/or field of application
of a patented process which conveys printed
impression from high-grade coated paper
to thin unsupported Him, with little distortion

ANEW METHOD of reproducing printed matter in
black and white and in full color on plastics film has
been developed by Joseph Mrazek, New York. Fields of
possible application range from packaging to textbook color
plates, and from reproducing old masterpieces to a new
medium for stage design. Although the process has not yet
been tried out commercially, it is said to be economical, and
sample prints show sharp definition and an almost three-
dimensional effect.

In essence, the process consists of the transfer of a pattern
printed on high-grade coated paper to cellophane' and other
cellulosic films, vinyl, rubber hydrochloride, butyral and
many other types of thin, unsupported film. The printed
paper is removed from the press in roll form and run along a
belt for calendering with a liquid film-forming resin, which
must be compatible with the ink used in printing the paper.
After drying, the film is stripped from the paper, leaving it
blank, printed impression having been transferred to film.

Although there is some intermixture of the printing ink
with the dissolved substances of the film-forming mass when
it is transferred, the distortion of the pattern is said to be
insignificant. By using water-insoluble, film-forming ma-
terials and a thoroughly dry water-insoluble marking com-
position, which is preferably free from oil, an exact repro-
duction is produced in the body of the film. Inks containing
oils are not, however, excluded from the process, for many
oils are compatible with the cellulose derivatives, for ex-
ample, in producing lacquers which dry to coherent films.

The film-forming mass is allowed to set or harden before
it is stripped from the paper casting surface. The film may
be translucent or opaque, and of any degree of rigidity. It
would appear best, however, to use the translucent, flexible
form on which the pattern is equally visible on both surfaces.

An interesting aspect of the process, which has been pat-
ented by Mr. Mrazek, is that the ink or marking composi-
tion can consist of substances which are plasticizers or
modifiers of the film material.

An alternate method of using the process, more prac-

ticable for short runs, perhaps, is to make a paste of the
film-forming mass with a suitable low percentage of liquid
ingredients. Two or more layers of the paste can be
mechanically applied, as by a roller, in order to produce
a film-forming mass of any desired thickness.
. Among the fields of application which have been ex-
plored, packaging seems to be outstanding. Both flexible
films and rigid sheeting, which are used now, can be made
far more attractive with colorful pictures. Very thin film
would lend itself to waterproof labels for bottles which
would be more smooth and durable than paper labels.

Other possible uses include maps, charts, and inserts for
books, periodicals and advertisements. Instruction manuals,
for the study of anatomical organs or automotive mechan-
isms, in which sectional views are superimposed on each
other in a series of films, are another possibility.

In conjunction with Boris Aronson, the noted stage de-
signer, Mr. Mrazek has been working on a method of
transferring an imprint to canvas. Reproductions on canvas
can be used as labels, calling cards, postcard reproductions
of paintings, book covers and bindings, and the like.

Mr. Mrazek differentiates his process from that in which
pre-formed markings with fusible composition.-, on a sheet
of paper are transferred by means of heat and pressure, as
well as from the familiar decalcomania process, in which
the transferred impression lies entirely on the surface. In
his method, it is said to be transferred into the interior of
the film-forming mass. KXD

pecially in cheap wood handles, which arc made with ant"
matic shapers. The same defect occurs in expensive wood
handles, which are hand turned, though to a lesser degree.
Even so, the dimensions vary from handle to handle to an
extent unheard of in precision molding.

This lack of uniformity in wood handles slows down pro-
duction and adds to their cost. The one major assembly
problem in paint brush manufacture is the attaching of the
metal ferrule in which the bristles or fibers arc set, to tin-
wood handle. The ferrule has to he slipped on the brush
handle like a collar, by hand, tapped into position and then
nailed, riveted or otherwise attached in place. Xow, since
the dimensions of the ferrule arc standard for different size
brushes, those wood handles which vary too much in dimen-
sion from the specified size cannot he joined to the ferrule
and must be discarded. And one brush manufacturer among
the six largest reports that on an average between 10 and
15 per cent of the wood handles ordered in any one size are
either too large to accommodate the ferrule, or so small
that they "swim" in it. In addition, the time and labor
lost with mismatched handles must be chalked up on tin-
expense side "f the ledger and added to the cost of those
handles which do fit.

The dimensions of the handle also influence the length
to which it will fit into the ferrule. I-'or example, a handle
which is too thick will permit the ferrule to slide up on it
only part of the required length. Though these handles may
not have to be discarded, the assembled brushes are not uni-
form in appearance, since the ferrules are joined at varying
lengths along the handles.

Variation in wood handle dimension contributes to pro
duction slowdown and high cost in still another respect.
Brush manufacturers are accustomed t" stamping their
trade name in roll leaf on the gripped upper portion of the
handle. For any given si/c handle, the stamping machine
is set at a pre-dctermincd height in order to deliver a clear
impression. However, when the gripped portion is thinner

or thicker than the size ordered, the impression delivered
by the machine will either be too faint, or so forceful as
to break the surface of the wood. Often the stamping ma-
chine has to be reset when the operator spots a handle in
advance which he knows is not of the right dimension.

All these difficulties are eliminated with the uniform di-
mensions obtained in molded plastics handles, which provide
a snug clip-on fit. This has led to the idea of automatic
assembling by machine an impossible procedure with wood
handles. Mutual Metal and Plastic Corp. has already de-
veloped such automatic equipment with E. Robinson Co.,
which is promoting its sale among brush manufacturers for
use with the phenolic handles.

For their uniformity alone, plastics could make a strong
bid for the brush handle market. But they are also superior
to wood as a handle material in other important respects.
First, molding makes possible a valuable short cut. Before
the metal ferrule can be riveted to the wood handle, as it is
in better grade brushes, the wood must be drilled to receive
the rivet. When plastics are used, this operation is by-
passed because provision for the holes can be made in the
dies.

Again, molding makes possible the economical produc-
tion of curved handles, which would be difficult or too costly
to make of wood. It is this line, which can be produced com-
petitively right now, which is being offered to distributors.

The phenolic handles are designed with a shoulder which
meets flush with the ferrule on assembly, so that there is
no overlapping of the ferrule on the handle. This feature,
provided usually only in expensive wood brushes because
of the cost involved, eliminates that accumulation of paint
in the space ordinarily present where the ferrule overlaps
the handle. It is patented by Mutual.

Swaging Is Economical

For inexpensive brushes, swaging, a method of attach-
ing the ferrule to the handle, is effected more economically
and provides a better anchorage in plastics than in wood.
Now in use on 10^ wood brushes, this method calls for a
pressing or rolling operation which causes the ferrule to
bite into the wood in a l /%" dented band. This bite alone
holds the ferrule and wood together without the aid of
nails or rivets. However, the denting process subjects the
wood to a severe strain, and sometimes tears the handle.
But with plastics the mold has been designed to provide a
groove in the handle for swaging. This patented method
makes for a sturdy joining and minimizes cracking.

Though phenolic handles are slightly heavier than wooden
ones, the difference is negligible in the common size brushes.
In the 5" and larger brushes, which are not yet on the
market, the weight is being reduced by blocking out the
inside portion of the handle in the mold. This would, of
course, also reduce the amount of molding compound per
unit. .

From the marketer's standpoint, plastics handles present
several familiar selling points besides their functional prop-
erties and potential colorability. They are pleasant to
touch, they have a comfortable balance because of their
weight-volume ratio, and they can be produced in graceful,
eye-appealing shapes. Finally, the distributors have a new
sales approach, for which they have long been looking. All
of these factors have added up to make the reaction to the
new handles highly gratifying, Baker reports. The line is
expected to be moving from jobbers to retailers by mid-
February.

Baker's present merchandising plans call for using the
plastics-handled brush as a leader. Since brushes are sold
in assortments made up of wood and plastics, the latter
will serve to carry the load of the wood handles.

Ultimately, Baker plans to introduce dealers to the new
brushes by means of a direct mail campaign now being de-
veloped. For display purposes, the company intends to

package the brushes in a plastics window envelope on a
stand painted in aluminum and black.

Mutual Metal and Plastic makes its own dies and has a
molding capacity of about 1,250,000 handles monthly, which
will be stepped up if the demand shapes up as expected.
RCA electronic equipment is used to preheat the preforms,
and experimental work is done in a Hydrotherm unit made
by Despatch Oven Co., with the preforms used for the larger
handles not yet in commercial production. The handles are
plunger molded on an Improved Paper Machinery Com-
pany (Impco) press and two Watson-Stilltnan presses. END

Calendered Vinyl Flooring

(Continued from page 29)

in the bright Florida sunshine have caused no change in
hardness or appearance, he added. Accelerated heat aging
tests also showed little change in hardness.

Recovery from indentation is also an important factor in
floor covering. All floor coverings show some indentation
under chairs and tables, with vinyl flooring showing less
indentation than both linoleum and rubber, due to its greater
hardness. The material has shown excellent indentation
recovery, exceeding both linoleum and rubber.

As a supplementary item to its vinyl flooring, the (Jood-
year company is also producing a vinyl cove base of tin-
sel-on type, top and bottom edges sharp to prevent collecting
of dust and dirt.

The material is produced by an extrusion method and can
be obtained in lengths up to 50 ft.

Like the flooring material, the cove base is thermoplastic
and can be easily formed to fit sharp inside and outside
corners as well as small rounded inside and outside corners,
or can be formed around a small continuous arc to make a
complete circle. Since it is of the set-on type, it eliminates
the need of accurate fitting of the floor material along the
walls, thus reducing installation time. Being flexible, it will
conform to minor wall and floor irregularities, and is so
designed that it supports itself at the point of curvature, yet
does not require a perfectly square and sharp corner at the
juncture of wall and floor surfaces.

Considering the problem of installation, Goodyear vinyl
flooring is more thermoplastic than most resilient floor cov-
erings on the market today. However, installation is essen-
tially the same as with any other type of covering.

The flooring material itself must be brought to a tempera-
ture of 70 before unrolling, and then laid out flat to permit
the material to lose the curvature of the shipping roll. The
cove base, too, which comes in coil form should be given the
same treatment.

Fits Contoured Surfaces

Goodyear vinyl flooring can be formed to fit contoured
surfaces. This is accomplished by heating the material and
forming it to fit the contours while warm. The material can
be heated on the job by means of radiated heat from infra-
red lights, electric resistance heaters employing reflectors to
concentrate the heat on the area to be formed, and blow
torches. If an open flame is used, care must be taken to see
that the material is not over-heated. It may be flashed up
the wall from the floor to act as a flash-type cove base. If
the material is heated and formed, a metal binding strip is
not necessary.

The material can easily be cut into tile if it is heated
before being cut. The heat should be applied only to a small
area surrounding the path of the knife. This can be accom-
plished by means of two electrically heated platens that will
heat the material from both the top and the bottom surfaces.
The platens should be approximately Y$ of an inch wide,
and long enough to reach across the tile cutter. The top
platen should be movable up and down like the hold down

PLASTICS

FEBRUARY 1948

bar, and both platens should be movable along the tile cutter
table to adjust them for whatever size tile is desired. Thus,
when one cut is being made, the material is being heated for
the next cut.

All sub-floors must be smooth, even and free of dirt, paint,
oil, wax and other residues. Old strip boards must be sanded
smooth, and ajl broken or loose boards must be repaired or
replaced. Badly worn floors may be conditioned by installa-
tion of hard plywood, the edges nailed on 6" centers and the
rest of the area random nailed on 4" centers with resin
coated flat head screw type nails. All plywood joints should
be sanded smooth.

Concrete floors should be smooth troweled and all cracks
filled. New concrete floors should be washed with muriatic
acid or other alkali neutralizing agents, thoroughly rinsed
and dried. Composition floors must be treated in the same
manner as concrete floors.

While neither moisture nor alkalis will injure the vinyl
material, it is not recommended for installation on floors in
direct contact with the earth, whether on or below grade,
due to adhesion problems caused by osmotic and hydrostatic
pressures.

Same Underlayment Used

Underlayment is used with Goodyear vinyl flooring in
the same manner as it is used with other resilient floor
coverings.

All seams of vinyl flooring should be double cut to insure
tight joints. Cutting can be greatly facilitated by heating
the material between 120 and 140, thus eliminating burrs
which may result from cutting at a lower temperature.
Should burrs result, however, due to inability to elevate the
temperature to the 120-140 range, they can be rolled or
burnished into the joint with a small hand roller or with the
head of a carpenter's claw hammer. Before burnishing, the
seam should be dampened slightly with a wet cloth, the
water acting as a lubricant, permitting the hammer head to
slide easily, forcing the burr into the joint and preventing
marring action on the surface of the vinyl.

Cutting and Handling Is Simple

Because the vinyl is thermoplastic, it is possible to sim-
plify the cutting and handling problems.

A pre-cutting flooring heater has been developed pri-
marily to heat the edges of a lapped seam which is to be
double cut. The heater consists essentially of two electrically
heated platens, formed from one piece of metal of high heat
conductivity, and positioned one above the other.

The platens are relatively long and narrow, and between
them is clamped an efficient electric resistance heater. The
heat is controlled by an adjustable thermostat, and insulated
handles are provided. The space between the platens is such
that a single thickness of flooring can be inserted. Since
both platens are hot, the two thicknesses of a lapped seam
can be heated simultaneously.

Heating of a lapped seam is accomplished by positioning
the heater at one end of the seam to be cut, and permitting
it to rest there until the material is heated to cutting tem-
perature. It is then advanced along the lapped seam, a dis-
tance equal to its length, and the healed section cut. When
the cut is made, the heater is again advanced and the cut
continued. Thus, in this way, the lapped seam is progres-
sively heated and cut in lengths equal to tlie length of the
heater.

The heater can also be used in trimming and edge fittings.
In this application, the material is first scribed in the usual
manner. The heater is then positioned so that it envelopes
the floor covering and is progressively moved along the line,
heating the material in advance of the cut.

Pre-cutting flooring heaters are manufactured in two sizes
at the present time. The lengths are 29" and 49". END

(S.

Molding compounds and presses are needed
fo develop India's infant industry. A
joint Indo-American sponsorship is to be
sought to build up this native industry

A PANEL OF PROMINENT industrialists and en-
gineers in the plastics field, appointed by the govern-
ment to draw up a program for the expansion of the Indian
infant plastics industry, has recently submitted its report.
It has recommended that the molding industry be expanded
to use about 3,000 tons of molding powders annually during
the next five years.

Most of this will have to be imported. Before the war,
Japan used to supply it ; Great Britain has now stepped into
first place. Due to the lack of reliable importers of plastics
materials, the United States supply has been irregular. It
is hoped that this situation will be remedied. The panel
has also recommended that the duty on molding powders
should be reduced from 30 to 15 per cent.

The panel has drawn attention to the fact that the 80-odd
15 to 100-ton compression presses currently in operation are
antiquated and of an uneconomic size, and need immediate
replacement if the Indian plastics industry is to withstand
foreign competition. It recommends automatic presses of
a minimum capacity of 100 tons as best suited to India's
needs. There is, thus, a market in India for a large number
of these automatic presses, of which a few were recently in-
stalled. There are only half a dozen injection presses in the
entire country.

Although India has a favorable balance of trade with the
United States, her presence in the sterling bloc and adher-
ence to the dollar pool preclude heavy imports from America
and favor British exports. This fact partly explains the
predominance of Britain in the field of Indian plastics im-
ports. However, the Indian Commerce Ministry has adopted
a conciliatory attitude toward imports of machinery, which
should help U.S. manufacturers fill Indian orders for auto-
matic plastics presses.

Most Indian plastics firms are custom malders. Molded
products have been confined principally to electrical goods
and accessories, ashtrays, desk sets, cups, saucers, tumblers
and combs. A recent survey revealed that there are 48 plas-
tics molds in use.

Two central die-making establishments are to be shortly
established in Calcutta and Bombay by the government, if
adequate private capital is not forthcoming.

India is woefully short of plastics technicians. The gov-

27-Oct. 2.

eminent is considering a proposal to grant a large number
of scholarships to technicians and students to study the lat-
est developments in the plastics field in the United States.
Forty plastics firms recently formed the All-India Plastics
Manufacturers Association with headquarters in Bombay.
This Association is also sending a delegation to the United
States to study the American industry and to explore means
of cooperation such as led to the establishment of jointly
owned rayon and fertilizer plants.

Inadequate utilization of coal tar and limited petroleum
resources are major drawbacks to the development of a
domestic plastics materials industry. However, two plants
are being built to produce calcium carbide. If the know-
how and skilled technicians now lacking are forthcoming,
India plans to produce in the next five years: phenol for-
maldehyde (1,500 tons), cellulose nitrate (2,000), urea for-
maldehyde (500 tons) and cellulose acetate (1,000 tons).

Investigations by the Council of Scientific and Industrial
Research have resulted for the first time in the manufacture
of phenol formaldehyde molding powder on a considerable
scale. Five firms have started manufacturing it, although
the quality has not yet been standardized. Also, the govern-
ment of the princely state of Mysore India has established
a small formaldehyde plant.

India's vast agricultural resources have led to an increas-
ing interest being taken in the exploitation of natural resins.
India has a virtual world monopoly of shellac. Howevef,
the industry is passing through a grave crisis on account of
its replacement by vinyl resins in the United States, and
it is trying to adjust itself to present conditions by lowering
the price and developing new uses for lac.

Prospects of Development Are Bright

Prospects for the development of a cellulose plastics in-
dustry are bright because of the country's vast resources of
cotton and molasses (source for acetic anhydride). An-
other promising field is the manufacture of resins useful in
insulating varnishes, stove enamels, flooring and lining ma-
terials, from the shell liquid of Bhilawan nut (commonly
known as "marking nut") which, like cashew shell liquid,
yields a phenolic constituent. Currently, over a thousand
tons of cashew shell liquid are exported annually from India
to the United States.

Waste products of the Indian jute industry and coffee
beans and coffee husks are other material sources being
studied. END

Streamlining

are generally avoided. Curved areas mold more easily,
have a better appearance than flat ones, and are also less
subject to warping.

All these factors must be taken into consideration; all
are designing "musts"; and all tend to encourage stream-
lining in the design of plastics products. These considera-
tions are brought about by the limitations inherent in mold-
ing. The real danger to good plastics design, however, is
not the limitations imposed by the mold, but the great
temptation which molding offers to the unwary to indulge
in design excesses. It is not so much a question of whether
the product is to be streamlined at all, but of the extent
to which the designer shall go. The most elaborate and
gaudy effects can be molded at but a trifling additional cost
per part. This factor alone has been responsible for many
of the abortive shapes that have been conceived in the past.
The urge to ruin an otherwise honest design by going
"whole-hog" with streamlining simply because to do so
will cost no more, is sometimes well-nigh irresistible.

We have discussed the tangible factors which bear on
the streamlining of plastics products, but there is yet an-
other element that must always be considered which has
been responsible for some of the worst streamlined atroci-
ties committed by the industry. We refer to the pressure
brought to bear on the designer by the manufacturer the
man who buys our plastics parts and bits and pieces.

The manufacturer very often decides that people will
insist that his product be streamlined that it won't sell if
it isn't be it egg-beater or bedroom doorknob. Anyone

with the slightest knowledge of merchandising methods
knows that this is not true and that it is the manufacturer
and his advertising agency who start trends and fads (as
witness the new fall styles in women's clothes). The con-
sumer merely gets caught in the tide. Many of the current
examples of useless and pointless streamlining represent
the taste of neither the designer nor the consumer, but
merely a whim of the manufacturer himself. He insists
that products be over-streamlined and otherwise designed
down to the market. The customer has no choice at all in
the matter ; he can buy only what is ultimately offered for
sale.

As evidence we need only point to some of the really
good design to be found in custom-built furniture, beyond
the range of the mass pocketbook. The mere possession of
money does not predicate good taste or an appreciation
of art, but people with money can and do buy furniture
that is several cuts above the mass-produced product in
both appearance and serviceability. There is little doubt
but that a great majority of those who must patronize the
mass markets have equally good taste and similar desires.
They would buy analogous products, if they could get them.

The sober truth is that the public could have comparable
design and quality in the mass-produced items if the man-
ufacturers were willing to give it to them. Often they
could have a better product for less money. Sometimes
streamlining has added needless cost to the product you
buy. A typical example of such over-emphasis on stream-
lining recently harassed a plastics designer.

The problem was a design for a housing for a machine
to be used in grocery stores. The mechanism was of sound
design and of a shape that was well adapted to a sleek func-
tional housing that was easy to mold and could be quickly
dismantled for cleaning. In short, the application was a
natural for good, all-around design. Did the customer like

the proposed design? He thought it was wonderful, but
it wasn't streamlined and so it wouldn't appeal to a grocer !

The designer conformed. What else could he do? At
the insistence of the manufacturer, he streamlined the thing.
He changed a broad, simple radius to a series of compli-
cated compound curves, included a sharp depression that
broke up the smooth simplicity of the top area but did,
without question, cut down the potential wind resistance.
When he had finished he had a machine that looked as if it
could fly from counter to counter under its own power.

That streamlined beauty will work, but not nearly so
well as would have the original design. It won't be nearly
as easy to clean, either. And the changes in shape, be-
cause they involved expensive machining methods in mold
construction and entailed additional finishing operations,
added over 20 per cent to the cost of the housing.

Some products get off more easily. Often just a silly
little fin planted on the front side of a molding will give
it that desirable, but totally unnecessary, quality of motion.

The whole matter of streamlining resolves itself into a
question of integrity. Simple functional beauty is not come
by easily. It is far easier to provide an effect that is
"original" or "different" by complicating an existing design
with a few streamlined flourishes than it is to achieve new-
beauty through simplicity.

Ample proof of this is furnished by the many gadgets
which, instead .of making living easier, merely serve to
complicate it. Their novelty appeals to us; we buy them
and show them off for awhile; then we promptly toss
,them into the discard and return to old, accustomed ways.
Most gadgets are not inventions, but only elaborations on
an existing idea, and their very intricacy defeats their pur-
pose. Nearly every smoker has at various times owned a
half-dozen different types of patent lighter, yet 99 per cent
always revert to the lowly match. The answer to a portable
lighting device is not an infernal machine with eleven
moving parts, but a permanent match. And the answer to a
thousand other design problems is just as simple and just
as hard to achieve.

Yet functional beauty once achieved is ageless. It will
survive fad and fashion because its appeal is based not
on fancy but on need. In the past this beauty was evolved
over long periods of time through trial and error, with the
customer used as a proving ground. Today we live in an
age of speed. Experiment is mostly confined to the labora-
tory and the drafting board, and the public is no longer
called upon to share the growing pains of product develop-
ment. The designer has a great opportunity, and a cor-
responding responsibility.

For the answer to the question "Should this plastics part
be streamlined," the designer need only ask himself another
question: "Must it be?" END

ings as packages for retail merchandise, and in electric
appliances, lighting fixtures and airplane parts. The auto-
motive industry is an especially large user of acrylic molded
parts for radiator ornaments, edge-lighted instrument panels
and dials, lenses, reflectors, steering wheel medallions, and
tail and stop-light assemblies.

The shatter-resistance of acrylic sheets and molded parts
has led to their use in applications where the safety factor is
important, and also insures a long life to all objects made
from the material. Safety masks and goggles, fabricated or
molded, protect the wearer from flying particles and provide

undistorted vision, in addition to being light in weight.
Machine guards have the same advantages, while hospital
equipment such as oxygen domes and bassinets also benefit
from the high impact strength of the acrylics. While they
are not literally unbreakable, their resilience and strength
enables them to withstand heavy blows that would shatter
many other materials. Also, when they do shatter under a
violent blow, they break into large and dull-edged pieces
rather than sharp, jagged ones.

Acrylics have been fabricated in many forms as industrial
production aids. A simple but effective example is the con-
tainer for spools of nylon thread devised by J. S. Cuthill,
for Interstate Hosiery Mill, Lansdale, Pennsylvania, which
is credited with making possible a sizable increase in the
production of nylon hose. This device is merely a Plexiglas
box measuring 18"x8"x5" with a tight-fitting hinged lid,
serving as a container for the bobbins of nylon thread
used in sewing the long seams up the back of nylon hosiery.

The machine which does this job runs so rapidly that an
entire seam, from toe to top, is completed in a very few
seconds. Each individual stitch must be made with light-
ning speed, and thread from three separate bobbins is used
in making it. However, this stitch will form only if the
tension on each thread has been correctly adjusted. While
cotton or rayon offer little difficulty once the tension is set,
nylon presents a difficult problem, for a bobbin of nylon
thread picks up enough moisture in a,n hour to necessitate a
new adjustment of the machine tension. In many hosiery
mills, extra crews of machine adjusters have been required
when a shift from rayon to nylon is made.

The obvious solution is to enclose the bobbin spindles to
protect them from the changing humidity in fhe room. Since
bobbins should be visible at all times to show up defective
threads before they foul the machine, a metal closure is
not practicable. Glass has also proved unsatisfactory, since
moisture condenses on the inside surface if the temperature
of the shop drops sharply, and it is subject to cracking.

Acrylic Boxes for Bobbins

The acrylic box, with three small holes in the lid for
passage of the thread and three pins in the bottom to hold
the bobbins, proved an ideal solution. It is fabricated by
M. M. Gottlieb and Associates, Allentown, Pa., and Devon-
shire Plastics and the Amplex Corp., both of Philadelphia.

Since the boxes were installed, skipped stitches have be-
come practically unknown at Interstate, improving the
morale of the workers as well as increasing production.

In this connection, an example of how acrylic parts can
replace metal, with improved fabrication and greater beauty
resulting, may be cited. In a recent redesign of its electric
water coolers, the Cool Stream Corporation, Brooklyn, New
York, has successfully adapted top plates of gaily colored
"Lucite" acrylic. Comprising the entire bowl, they measure
approximately 14"xl8"x3", and are available in a wide
variety of colors to match and complement the colors of the
41" cabinet, which has painted rolled steel sidewalls, and
a circular, stainless steel front.

Designed in an elliptical shape with the rear side flat, the
tops posed a difficult deep-drawing problem to the fabrica-
tor, the Steiner Manufacturing Co., Long Island City, New
York, which finally solved it by using reversed suction and
a male plunger simultaneously.

According to the manufacturer, the acrylic tops have sev-
eral advantages over the old type top of stainless steel. In
addition to their intrinsic beauty, they are very light, though
strong and resistant to abuse. They can be cleaned easily,
and resist most acids and alkalies. Once the basic fabrica-
tion procedure was established, production became relatively
simple and fast. The many colors available make it pos-
sible to harmonize the coolers with nearly any interior deco-

ration motif. Finally, the plastics is readily available, unlike
other materials previously used as water cooler bowls.

The new tops are being manufactured in both the "bub-
bler" type cooler and bottle type, in which the bottle is
mounted directly to the plastics top into a steel holder.

As a result of successful tests, the manufacturer is guar-
anteeing the new type cooler for five years, with the proviso
that specified procedures for care and cleaning are complied
with.

The manufacturers of acrylic plastics have in recent years
developed several interesting new forms of the material that
have widened its range of applications. One of these is the
imparting of corrugations to the normally flat sheet ; another
is the application of patterns to its surfaces. In corrugated
form, acrylic sheets gain a high degree of longitudinal
rigidity while retaining horizontal flexibility, making them
useful as screens, partitions, doors, exterior facings, and in
other architectural applications. Designers find these varia-
tions from a flat surface of esthetic interest, and are using
them in applications where standard acrylic sheets have
heretofore been most suitable. One advantage of the cor-
rugated form is that surface abrasion is not readily apparent
a useful feature in applications involving constant surface
wear. This type of acrylic is offered in several degrees of
corrugation and in sheet sizes up to 64"x79".

Patterned acrylic sheets, in somewhat smaller sizes, are
now being produced by applying various designs to their
surface during the casting operation. Patterns include
fluted, ribbed, pebbled, dotted, frosted and cross-hatched de-
signs, and may be applied to both sides of the sheet. The
methods by which smooth-surfaced acrylic sheets are formed
and fabricated are equally applicable to patterned material,
which has the same physical properties as standard acrylic
sheeting except that of complete transparency.

The decorative advantages of patterned surfaces have led
to the use of this material in the home furnishings field,
while its functional value ,as a medium for daylight admis-
sion coupled with privacy has established it in architectural
applications, as office partitions and interior door glazing.

Patterned acrylic sheets are also produced in corrugated
form where a combination of these two variations of the
standard acrylic sheet is desired.

Steady progress has been made in the development of
molding powder formulations which impart high heat re-
sistance and a maximum degree of transparency to molded
parts, until today they range in heat distortion temperature
from 160 F up to 210 F.

The point is often made that plastics need not necessarily
be used alone, but can be combined effectively with other
materials, notably metals. The acrylics have proved them-
selves to be happy partners in such marriages, because of
the effective textural contrast they afford.

The major suppliers of acrylic sheets and molding
powders are the DuPont Company (Lucite) and Rohm and
Haas Company (Plexiglas). END

Electronic Sealing

Spectrum Engineers, Inc.

540 North 63rd St., Philadelphia. Pa.

Specifically designed for the elec-
tronic sealing of cellulose acetate box
corners, production of the Spectrum
Electronic Corner Stayer is based on
principles developed by Eastman
Kodak Company's Kodapak Demon-
stration Laboratory.

The new unit, which will seal any
size container up to a maximum cor-
ner depth of 4", employs an RCA
Model 100 AV Generator together
with a special sealing head (illus-
trated), to produce a narrow, per-
manently welded seam. This method promises to speed produc-
tion, reduce waste by eliminating "throwouts" resulting from
cement smears, improve box appearance, lead to greater uni-
formity of product, and eliminate distortion sometimes caused by
cementing operation usually employed in box sealing.

Guides are provided on sealing head for aligning boxes and
speeding up production. Mounted on a work stand which also
holds the generator, the sealing head is ready to plug into any
standard 110-volt AC outlet; requires no compressed air,
vacuum line, or other special setup for operation. Precision ad-
justments provide for quick changeovers for runs of different
size boxes and different sheet gauges (826)

IF YOUR PRODUCTION REQUIRES
MULTIPLE CAVITY MOLDS...

Good bobbing can take the headache out of many
plastic production problems where multiple cavity
molds are needed. Machining may be the better
method for some types of molds, but bobbing is the
more satisfactory process for producing many types.
Naturally, we can't tell you which method is better
for your molds without knowing your particular re-
quirements. But this helpful booklet points out the
advantages of both bobbing and machining and will
answer many of your questions about both methods.

It gives the do's and don't's of bobbing, tells how the
master hob is produced and how it, in turn, is used
to produce numerous duplicate bobbed cavities,
quicker and at lower cost.

During more than 25 years, we have continuously
gained technical knowledge by producing thousands
of compression, transfer, and injection type molds.
This specialized know-how equips us to produce the
hobs, bobbed Cavities, and machined molds you need.

Marktt Restarch Engineer

Improvement of Nylon Fibers

The development of nylon has provided the textile industry
with one of its most valuable materials. Produced from synthetic
superpplyamides, the nylon fibers possess high strength, low
solubility in organic solvents and a high melting point.

Some of the nylon materials fabricated in the early days were
a bit stiff, possessing a heavy hand caused by an inferior degree
of resilience or crease proofness, in comparison to wool and
similar materials. This deficiency was partially overcome by a
formaldehyde-baking treatment on drawn nylon which increased
the melting point, dye receptivity and recovery from deformation.
In another effort to overcome the stiffness problem, nylon fabric
was subjected to a heat treatment in the presence of an alcohol or
other partial solvent ; the fabric was heated over its width against
a heated surface to a temperature approaching the melting point.
Recently, Allan K. Schneider, Wilmington, Delaware, discovered
a conversion-cross linking process which further improved nylon
softness, drape and resilience, and provided a higher melting
point and an increased resistance to the action of organic solvents.
There are three steps in the Schneider process: (1) Undrawn
polyamide yarn (polyamide yarn in which the filaments are
essentially unoriented molecularly along the filament axis) are
reacted with a solution, having a pH below 3. of formaldehyde
and an oxygen-containing acid catalyst in alcohol until at least
one per cent, but not more than 20 per cent, of the hydrogen-
bearing amide linkages are substituted by N-alkoxymethyl
groups. (2) Treated yarn is cold-drawn. (3) Filaments or yarn
are crosslinked or insolubilized.

Schneider found that two basic factors contributed to the
nylon-fiber improvement: (1) The degree of alkoxymethyl sub-
stitution is lower than that previously used, providing the poly-
amide with properties which differ markedly from both the un-
modified polyamide and polyamides of the higher alkoxymethyl
substitution (above 20 per cent). The lower substituted polyamides
retain the ability to cold draw, being relatively insoluble and
resembling in fiber form the initial polyamide, but yet having
increased softness, pliability and dye receptivity, and the ability
to crosslink adjacent chains by splitting out alcohol or water
>etween substituted and unsubstituted amide groups. (2) The
low degree of substitution required in this process can be intro-
luced into a polyamide fiber without destroying its form since
ndrawn and consequently unoriented polyamide filament is much
more chemically reactive toward the formaldehyde-alcohol solu-
tion than the drawn and oriented fiber. The latter is substantially
unreactive to formaldehyde, whereas the undrawn filament is
readily reactive, particularly with a strong acid catalyst at a pH
level below 3.

In one test application of the process, Schneider took a skein
f one part undrawn polyhyexamethylene adipamide 142 denier
M C l d In 40 parts of a solution containing 10 parts of para-
3 rmaldehyde, 10 parts of methanol, and one part anhydrous
oxalic acid, holding the skein in the solution for 8 min at a tem-
perature of 64C. The skein was then removed, rinsed for 5
ours in a one per cent aqueous ammonium hydroxide solution
and dried at 25 C. (A study of the skein showed that 6 per cent
the amide groups were substituted with a mixture of N-
ethylol and N-methoxymethyl groups.) The skein was then
back wound onto a spool and cold drawn to a ratio of 351-1
ien, the yarn was soaked in a one per cent aqueous oxaiic
ioution for 30 min at 25 C, dried in the air at 25'C and then
baked for 5 mm at 110C. The baked yarn was thereafter washe
in pure water to remove all residual acid. Tests with this yarn
reveaed that ,t was not soluble in m-cresol, had a tenacity
) of 3.8, a 24 per cent elongation at breaking point and
excellent dye receptivity. Temp, of zero strength was 280

Crosslinking of the polyamides can be effected by heat alone.
However, best results are obtained by impregnation with an acid,
followed by baking. In this step the acid need not be an oxygen-
containing one, and any acid having an ionization constant
greater than 1 X 1(H can be used. The acid used in the formal-
dehyde and alcohol treatment of the first step is usually used in
crosslinking. Polyamide filaments in which the alkoxyl group
of the N-alkoxymethyl substituent is unsaturated (has ethylenic
unsaturation) can be crosslinked by impregnating the filaments
with a solution of benzoyl peroxide or other organic peroxy
compound, followed by either baking or exposure to ultraviolet
light.

The treatment with acid or peroxide, when used, can be applied
before the cold drawing and immediately after the initial step of
treating the undrawn filaments with alcohol and formaldehyde.

Polyamides with a high molecular weight, or fiber-forming
polyamides which have an intrinsic viscosity of at least .4, were
used by Schneider in his research. These polyamides can be
obtained by polymerization of a monoaminomonocarboxylic acid,
or by reacting a diamine with a dibasic carboxylic acid in sub-
stantially equimolecular amounts, or by reaction of a mono-
aminpmonohydric acid with a dibasic carboxylic acid in sub-
stantially equimolecular amounts.

Acid catalysts which can be used in the Schneider process in-
clude oxalic, maleic, fumaric, p-toluenesulfonic ; generally, those
inorganic or organic acids which in concentrations between 3
per cent and 20 per cent in a methanol-formaldehyde solution
give a pH of below 3 and do not cause excessive degradation of
the polyamide.

Methanol is particularly suitable for this nylon-improvement
process. However, any aliphatic alcohol which is at least par-
tially miscible with formaldehyde can be used.

Thermosetting Adhesive* for Plywood

Plastics has become an extremely important factor in the
lumber and furniture industries. With thermosetting adhesives
which are quite stable, soft, have low curing temperature for
rapid setting, and are not brittle on curing, thus permitting wood
flexing, many unusual types of plywoods have been made avail-
able. An interesting example of this work is a three-ply thermo-
setting-bonded birch panel with a dry shear strength of 775 psi,
about 300 Ib more than standard panels permit, produced by Fred
W. Hoover, Wilmington, Delaware, using N-alkoxymethyl poly-
amides as a bonding medium.

In preparing the adhesive for this plywood panel, Hoover
stirred 30 parts of N-methoxymethyl polyhexamethylene adipa-
mide, having 1 1 per cent methoxyl and about .5 per cent methylol
groups, which correspond to an amide substitution of about 51
per cent, with 70 parts of 70 per cent aqueous ethyl alcohol (70
parts of ethyl alcohol to 30 parts of water) until a solution was
obtained; solution has a viscosity of about 900 centipoises at
25 C. To this solution was added one per cent maleic acid as a
catalyst. After the catalyst was thoroughly mixed in, the solu-
tion was brushed on the surfaces of the birch veneer (Via inch)
at a rate of about 75 Ibs of liquid per 1000 sq ft of glue line. The
solution was then allowed to dry at room temperature for about
two hr to permit most of the solvent to evaporate. The three
plies were then placed together and pressed at a temperature of
120 C at 55 psi pressure for 30 min. After the pressure was
released, the plywood was immediately removed from the press.
Testing this plywood with a plywood shear test developed by
the U. S. Department of Agriculture ' showed that the plywood
had a shear strength of 775 psi with 100 per cent wood failure.
The same plywood, after exposure to boiling water for three hr
tested while wet, had a shear strength of 559 psi, with a 77 per
cent wood failure.

Tests also revealed that the plywood was highly resistant to
repeated exposure to water and dry heat. When subjected to 10
cycles, consisting of two hr in boiling water followed by drying
for 22 hr at 60 C, the plywood exhibited no deterioration, warp-
ing or loss of strength.

The Hoover thermosetting adhesive can also be used to bond
paper, cotton, fabric, regenerated cellulose film, hydrolized vinyl
ester polymers, etc. The active -OH, NH and -NH groups in
these laminae enter into a chemical reaction with the N-alkoxy-
methyl polyamide to form strong layer bonds. END

John R. Hoover of Cleveland, Ohio, vice-president of the
B. F. Goodrich Chemical Company and Dr. D. S. Frederick, of
Philadelphia, Pa., vice-president of Rohm & Haas Company,
were re-elected president and vice-president, respectively, by
the Plastic Materials Manufacturers Association, Inc., at its
annual meeting held in New York. F. H. Carman was elected
secretary-general manager and John E. Walker, treasurer, of
the Association with headquarters in Washington, D. C.

New members elected to the Board of Directors are: C. F.
Hosford, Jr., vice-president Koppers Co., Inc., W. W. Knight,
Jr., general manager Plaskon Division, and Spencer E. Palmer,
assistant vice-president Tennessee Eastman Corp.

Also Harry Krehbiel, president Catalin Corp., and W. S.
Landes, vice-president Celanese Corp. of America, will continue
as directors along with Mr. Hoover and Dr. Frederick. Arnold
E. Pitcher, general manager of the Plastics Dept., E. I. du Pont
de Nemours & Company, a past president of the Association, will
serve in an advisory capacity to the Board of Directors.

The Resin Adhesive Division at their Annual Meeting in the
afternoon elected J. C. Garrels, Jr., manager of Lockport Plant,
Western Division, Monsanto Chemical Company, as its chair-
man for 1948. In addition to Mr. Garrels, the Managing Com-
mittee of the Division will include W. N. Shepard manager of
Industrial Glues and Resins of the Plaskon Division, and the
Division's retiring chairman, and R. G. Booty, assistant to the
president, Interlake Chemical Corp.

The Goodyear Tire & Rubber Co., Chemical Products Divi-
sion, was elected to membership in today's meeting.

Progress in the research project sponsored by PMMA at the
Massachusetts Institute of Technology was announced to the
industry during the meeting. Now entering its third year, this
project is directed toward a fundamental study of the engineering
properties of plastics. It became evident quite early in the work
that specialized testing equipment designed specifically for the
testing of plastics of all kinds would have to be designed and
built. A new machine devised by the Institute, and already in
use, is a combination of known principles of various types and
is the first of its kind to take advantage of recent developments,
particularly the use of servo mechanisms and electronic controls.

This machine permits the precise measurement of physical
properties of plastics, taking into consideration the importance
of time as a primary function; it provides constant rates of
stress, strain, crosshead motion, load application and permits the
continuous testing of a sample from tension to compression.
Auxiliary equipment include freely suspended and self-aligning
grips, a special bending jig, torsion and shear fixtures and special
extensometers operating through the servo mechanisms.

The new testing equipment, together with specialized instru-
ments for rapid determination of molecular weights and molec-
ular distribution, open a new horizon in plastics testing and now
complete the instrumentation for the Institute to proceed to the
main objective the study of the mechanical strain phenomena
of plastics as related to their molecular structure.

The work at the Institute is being directed by a Steering
Committee composed of Dr. D. S. Frederick for PMMA and
Professor A. G. H. Dietz of M.I.T. The technical men of the
Association Members together with representatives of A.S.T.M.
and S.P.I, have been assisting in this work. Results of the re-
search are made available to the industry through publication
in industry journals.

at room temperatures

'T-'HE man has just dipped his
J. finger into a new Geon water-
borne resin known as Geon Latex
31X. It will dry on his finger, in the
air, at ordinary room temperature,
rapidly and evenly.

If you package foods or deal in
fresh fruits and vegetables ... or if
you're looking for a better adhesive
... or want to make a water paint
with a water-impervious film that
will dry at simple room temperature
... or if you're dipping toys, gloves,
packages, etc., where the form has a
complicated shape and a thin flexible

wall or covering is required you'll
want to know more about Geon
Latex 31X.

The deposited film is flexible, but
contains no plasticizer. It is odorless,
resistant to grease, and has low mois-
ture vapor transmission. It won't
support a flame. Adheres readily to
paper, wood, fiberglas, and textiles.

A distinct advance, a cost-cutter,
a product-improver, you will agree
and we'll be glad to send our spe-
cial bulletin giving complete details.
We make no finished products from
Geon Latex 31X or any of our other

SOLVED THIS

PROBLEM IN PLASTICS

The Kiddie Seat Corporation of New York turned to us with a specific problem.
"There's the design", we were told, "follow it accurately. But we're not satisfied with
the hinge construction. That must be perfected. The final product must be rugged . . .
non-toxic . . . easy to clean . . . attractive in appearance. It must have a permanent
finish and provide a smooth rounded contour."

As a result of the cooperative efforts of NATIONAL LOCK specialists in interpretive
design, engineering, tool and mold making, molding, inspection and all of the other
phases of preparation and production, the job has proven highly acceptable in every
respect. Our wide experience in fields other than plastics proved valuable in many
ways, including development of a hinge that's "just the ticket".

Handles molded by Colt's M'fg Co. from Koppers' ethyl cellulose

When plastics have work to do ... a tough day-after-day
assignment . . . more and more manufacturers are calling
i the cellulosic plastics to handle the job. That's why this
Peck, Stow & Wilcox carpenter's brace and many other tools now
have handles of ethyl cellulose.

Handles of ethyl cellulose stay on the job . . . remain tough and
resilient at low temperatures . . . resist moisture and heat. They are han-
dles that hard knocks won't shatter, that can be quickly produced
by extrusion or injection molding, and can be readily machined.

IN THIS ISSUE we publish a full-scale study of
plastics merchandise as bought and sold by one of
the major chain store organizations W. T. Grant
Company. Anyone who is interested in the marketing
of plastics wares will want to read every word of this
frank article, for it quotes the unfavorable as well as
the favorable comments made by various key members
of the organization, tells what they like and dislike
about plastics, and for what these alert merchandisers
are looking. It also draws logical conclusions by
which everyone who has a plastics product to offer a
mass-selling store like Grant's, can profit.

Here, we wish merely to point out one fact which
has strongly impressed the stores' buyers that plastics,
alone among the common materials used in their mer-
chandise, have in general been priced lower than in the
previous year. To a merchandiser, price is paramount.
This does not mean that he will countenance a cheaper
product which does not have the requisite quality for
its purpose. But it does mean that, counting on a low
margin of profit and heavy turnover, he must make
every effort to obtain goods which will give the best
sales performance. Therefore, a general reduction in
the price level of plastics products makes him all the
more receptive to them.

AS IF MATERIALS suppliers didn't have troubles
enough. . . . One of them recently got a sizable
package from a molder who complained that his com-
pounds weren't flowing properly ; they wouldn't shape

the supplier please check up on the enclosed sample and
find out what the trouble was? . . . Said sample con-
sisted of nothing less than a steel bar which had been
blocking up the chute !

AT AN INFORMAL gathering, we were talking
about the quantity and variety of inquiries re-
ceived by plastics publications from their readers. As
an example we cited a letter which seemed to promise
good business to the extruders to whom we had referred
the writer. One of the group got quite excited about it.
Didn't we know, he asked, that his company represented
one of the extruders we mentioned? We said frankly
that we did not, because we could not keep track of the
miscellaneous types of organizations which acted as
sales agents for the multifarious kinds of plastics com-
panies. Branch offices were one thing; they were as

great a convenience to us as to the home offices. But
agencies which might and do handle any number of
products or kinds of equipment besides plastics are vir-
tually impossible to keep tabs on. Since merchandising
of products and services is now recognized as the num-
ber one problem of the industry, this factor is worth
thinking about. Some way must be found to promote a
company's active representatives as well as the parent
company itself, for they are all part of the same busi-
ness of broadening specific markets.

TO MAKE THE MOST of the great potential of
plastics in the lighting field, a meeting was held re-
cently at the General Electric Lighting Institute in
Cleveland which was attended by representatives of
both lighting equipment and the plastics industry. They
came to the conclusion that it would be highly desirable
to set up standards on light diffusion, transmission and
reflection ; mechanical strength ; heat and color stability ;
humidity; electrostatic properties; and fire resistance
characteristics.

Such specifications, it was felt, would make it much
easier for material manufacturers, plastics processors
and equipment manufacturers who use plastics com-
ponents, to carry on business with each other.

As a first step, the conference proposed that a com-
mittee be established whose members were to be chosen
by the Illuminating Engineering Society and the Society
of the. Plastics Industry, and it was recommended that
a smaller group be named to meet in advance of the
proposed committee to draft a tentative standard for
the latter to act on. Representatives of the Electric
Testing laboratories and of the American Society for
Testing Materials were also to be invited to the stand-
ards conference.

The consensus of the Cleveland meeting was that, for
the present, the committee should confine its work to the
illuminating and physical characteristics of plastics ma-
terials for fluorescent lighting. It is to be called "The
Committee on Plastics for Lighting."

Solid Plaskon Molded Color through and through . . . that means permanence

of finish, freedom from chipping or cracking, sparkling cleanliness, and

resistance to water, weak acids, soaps and other solvents.

The Lanfare Toilet Seat represents a radical step forward in the manufacture

of this type of houseware. The introduction of a wide range of beautiful, permanent colors

satisfies particular decorating requirements. The moldability of Plaskon permitted

structural designs that give the seat and cover great strength, which prevents splitting.

The feature of sanitation has profitable sales appeal.

This is another example of product development aided by the thermosetting

properties of Plaskon Molding Compounds, which include excellent dimensional

stability, low water absorption, non-softening action from heat,

and their ability to withstand common cleansing detergents and weak acids.

Plaskon Molding Compounds can be transformed into almost any distinctive, practical

design or size of product. A wide range of clean, brilliant, permanent colors is available.

The hard, non-porous surface of molded Plaskon will not tarnish, check

or corrode. It is impervious to the effects of alcohol, acetone, oils, waxes or greases.

Plastics Field Editor

A large manufacturer of educational de-
vices and electrical household appliances
now prefers plastics tor more than 300 parts
which were made originally by die-casting.
Molding made possible precision details
where these were required, as well as some
production economies. Company molds the
simpler components itself, and farms out
the more difficult jobs fo custom molders

WHEN A COMPANY has been set up for years to
manufacture its products by die-casting methods, it
is a reasonable assumption that it will only replace them
with plastics components for the best of reasons; and it
follows that the experience of such a company may well
serve as a guide to other manufacturers who are thinking
of using plastics materials.

The A. C. Gilbert Company, New Haven, Conn., has
long been known for its model trains, construction sets
and electrically operated household appliances. While die-
cast metal components still dominate their products, Gil-
bert has made use of more than 300 plastics parts in their
diversified products. Not only have these been rigorously
tested for their functional properties, but the products of
which they are a part are pre-tested by consumers; and this
' is specifically a test of the plastics component when it con-
stitutes the novel element of the product. Another index
of the company's earnest interest in plastics is that, after
it had decided that it wanted to use cellulose acetate for
a certain electrical appliance and the Underwriters' Lab-
oratories did not approve, Gilbert persisted in developing
the application until the approval was forthcoming.

Final measure of the company's stake in plastics is its
acquisition of its own molding presses. About eight years
ago, it installed several 50 to 75-ton Stokes compression

Components cf "Whirlbeater" include: (1) complete unit
with flame-resistant cellulose acetate shell, (2) the
rear part of shell, (3) front unit, (4) mixer blade

molding presses to produce phenolic handles and brush
blocks in some of its electrical products. When injection
molding came rapidly to the fore during the war years,
Gilbert was quick to see its advantages, and it now has four
12-oz Lester injection machines and has greatly expanded
its plastics applications by the use of thermoplastic materials.
Gilbert now has four compression molding presses.

Gilbert's policy on in- or out-molding will be of interest
to other manufacturers who use a sizable number of plastics
components. Despite the fact that the company has its own
machines, it only molds fairly simple parts in its own plant,
for it realizes that it lacks the know-how for producing
more difficult parts. These it prefers to turn over to custom
molders who have the necessary engineering personnel to
handle them with dispatch. Thus, it has had Shaw In-

Transfer molded components for toy locomotive motor com-
mutator. This replaces a fiber board part with brass ears

sulator Company, Irvington, N. J., doing its transfer mold-
ing, and it has also had work clone for it by The Waterbury
Companies, Waterbury, Conn., the R. E. C. Plastic Co.,
Holliston, Mass., and the Teal Molding Co., New Haven,
Conn.

On certain parts, Gilbert has long runs of butyrate on its
own injection presses. Rather than run the risk of con-
taminating it with other materials which a part may call
for, such as acetate, Gilbert has this part molded outside.
They also find it advantageous to let a custom molder do
the work because the latter then bears the responsibility
of seeing to it that there is no variation in the molding
compound formulation and that the part measures up to
specifications.

A review of some of the representative plastics com-
ponents in Gilbert products will show why they have been
made in those materials. To begin with the American Flyer
model railroads, which are designed from actual railroads
to a uniformly : )i" scale, the cars are molded from cellulose
acetate butyrate (Tenitc II). The fact is featured in the
presentation of every one of the various railroad sets in
the company's catalog, which, in summation, states the
case for them as follows: ''Molded plastic construction
makes possible new lightness of weight and new beauty of
finish. These ultra-modern cars are much lighter than die-
cast cars, and their permanent colors cannot flake or chip.
. . . Even such fine details as brake wheels, ladders, jour-
nal boxes and rivet heads are accurate reproductions of
the real thing." To this may be added the fact that the
material is dimensionally stable.

In various roadbed elements, plastics have been respon-
sible for simplifications and improvements. Originally, the
bed itself was made of tin. It had a three-unit track (one
being the current-carrying "third rail") ; it did not look
very substantial ; and the rails and terminals had to be
insulated. A change-over to molded phenolic provided a
more realistic looking roadbed, with H. O. gauge double
track which required no further insulation, since the plastic
has good dielectric properties.

Changeover fo Phenolic

This change also entailed the conversion of the crossovers
and switch road bed to phenolic. In the latter, six fiber
insulation plates were eliminated, as well as the mechanism
housing and most of a large metal cover on the underside
(see illustration). A number of small internal parts were
also dispensed with. At the same time, a sub-assembly of
Ibis device, the switch lens shutter, was simplified by being
molded of polystyrene. This piece, octagonal in shape, has
its sides painted alternately in red and green ; and light is
thrown on one or the other as the position of the switch
demands. Formerly, separate red and green glass lenses
were used. It was difficult to grind them accurately to the
close tolerances required in the installation. With styrene,
this difficulty is overcome, and it was no trouble to mold the
shutter with a shank which fits easily into the adjacent
metal part.

Being simpler and smaller, the new switch road bed low-
ered the assembly cost considerably, so that, although the
actual unit cost is higher now than it used to be, it is still
lower than the original part would cost at present produc-
tion schedules.

Plastics materials have also improved another lighting
unit in the American-Flyer sets the signal towers. Here
an acrylic rod (I.ucite is specified), with its light-piping
property, is used to travel the red and green lights. For-
merly, a large bulb was needed to give the proper illumina-
tion, and this was out of scale with the rest of the tower.

In the locomotive, phenolic has replaced a fiber board
.plate as the brush tub bracket, because it is less subject to
shrinkage and warpage while having the necessary in-
sulating value. In a recent development, the commutator

used in the engine has acquired a transfer molded com-
ponent. Previously it was made of fiber hoard to which
three ears were fastened with brass rivets. Now phenolic
compound is molded with a slotted and pronged copper
blank as an insert. Firmly anchored to the plastics during
the molding, the insert overlaps it and is trimmed after
molding to provide three ears to which the wires are at-
tached. This component is more economical to make than
the fiber part ; it is stronger ; and it does not warp because
it does not absorb moisture as the fiber piece did. '

Finally, the "rainbow cable" used in the model railroads
may be mentioned. This consists of four strands of wire
insulated with green, yellow, red and brown vinyl extrusions
and, to keep them from spreading out and entangling with
other elements, they are bound together with a transparent
vinyl coating. When the amateur railroader is ready to
set up his line, all he has to do is separate the ends of the
four strands sufficiently to make his connections with the
binding posts. These, too, are colored green, yellow, red
and brown, so that he doesn't have to call in an electrician
to make the respective contacts; the color correspondence
makes the task obvious.

In the electrical household appliance field, Gilbert has
made important use of flame-resistant cellulose acetate.
(Lumarith XF and Ko/>pers) the light weight, insulating
properties, appearance and feel of this material all con-
tributed to its adoption in the Whirlbeater mixer and Vita-
lator massaging device. In the latter, the two-part shell
made of acetate fits over a die-cast frame. This makes for
a 50% reduction in weight, and there is a further economy
in molding since it eliminates the elaborate trimming re-
quired by the die-cast part it replaced.

Softening, Distortion Tests

When Gilbert submitted the Whirlbeater to the Under-
writers' Laboratories for approval, the latter made the fol-
lowing tests. Six samples of the mixer were placed in an
oven held at 212 F for seven hours. At the end of this
period, each mixer was taken out to see if the material
would soften when handled. It did not, and neither was
there evidence of distortion.

For a mechanical strength test, three samples were
dropped from a height of three feet on a hard wood sur-
face. Each mixer was dropped three times, once on the
front end and once on each of opposites sides. While a
small piece of the front part of the enclosure was chipped
out of the first mixer dropped, no live parts were exposed.
The front part of the enclosure of the second mixer dropped
cracked slightly, but no pieces were chipped out. A small

section of the rear part of the enclosure extending back
about %" was chipped out of the last sample dropped, but
again no live parts were exposed.

In an abnormal operation test, three samples of the mixer
were placed on a soft wood board covered with tissue paper
with their rotors prevented from turning. The mixer was
then connected to a supply circuit of 120 volts dc and
allowed to operate until the motor failed, which took from
12 to 15 min. There was no emission of flame or molten
metal, and the enclosure did not ignite. Dense smoke issued
from each of the samples, but the tissue under the mixer
was neither burned nor charred. The enclosure of one of the
mixers was not deformed as a result of this test. The other
two enclosures were deformed slightly. No live parts were
exposed in any of the mixers.

The final test a crucial one was for flammability.
Three enclosures without motors were suspended in a hori-
zontal position. A bunsen burner was adjusted to give a
yellow flame J4" high, which was applied to the edge of the

enclosure for 30 sec. The flame was then removed and the
material allowed to continue burning until self-extinguished.
The test flame was then reapplied for 30 sec.

The material continued to burn for a short time after the
flame was removed. The longest time measured was 25 sec.
In each test the material burned slowly and was self-
extinguishing.

As a result of all the tests on the other parts as well as
on the plastics enclosure the Whirlbeater was judged to be
acceptably designed and constructed. Commenting specific-
ally on the enclosure, the Underwriters' Laboratories
declared that "the use of thermoplastic materials for the
enclosure of small electrical appliances is a relatively new
development even though such appliances .have previously
employed enclosures of thermosetting materials, e.g., phe-
nolic and urea compounds, which have proven acceptable
for this use.

"The phenolic and urea compounds are not affected by
the relatively low temperatures which cause distortion and
softening of the thermoplastic materials. The thermoplastic
compounds have relatively high resistance to impact and
for this reason are desirable for applications where this is a
primary consideration. The thermoplastic compounds of a
cellulose acetate base (either normal acetyl or high acetyl)
or ethyl cellulose are available in a large number of formula-
tions which permits the selection of a material having de-
sirable characteristics from the standpoint of softening,
resistance to impact and flammability.

Softening Points Vary

"The many compounds available vary considerably as to
this softening point as determined by ASTM test methods
and in general it can be stated that the highest softening
point is approximately 90 C. All of the compounds have
high values of impact in comparison with the phenolic and
urea compounds. Relatively few of the thermoplastic com-
pounds of either the cellulose acetate or ethyl cellulose base
are flame retardant or self-extinguishing. However, it is
possible to formulate these compounds so that they are
self-extinguishing as determined by ASTM test methods.

"In considering the use of thermoplastic materials for the
enclosure of this electric mixer it was necessary to give
consideration to the possible normal and abnormal condi-
tions which might affect the material. It was considered
desirable to have a material of high temperature character-
istics which would resist softening and distortion should the
mixer be placed on a hot surface such as a steam radiator.

"The material should resist mechanical abuse such as
would obtain from dropping the mixer from a table top to
the floor. Further, the material should be self-extinguish-
ing and should not soften or disintegrate sufficiently to
expose any live or current carrying parts when operated
under the most severe conditions likely to be encountered
in service.

"The temperature test conducted at 212 F for seven
hours demonstrates that the material is sufficiently heat
resistant to resist softening or distortion which might occur
under somewhat abnormal conditions of use which would
occur should the mixer be placed on a hot surface such as
a steam heated radiator.

"The enclosure offers adequate resistance to ordinary
abuse which might occur in actual use. The slight cracking
of the enclosures is not considered objectionable considering
that there was no exposure of live parts which would pre-
sent a shock hazard even though the mixer was dropped
from a height of three feet on a hard wood surface.

"The abnormal test which consisted of stalling the rotor
is a condition not liable to occur in service. The slight
deformation of the enclosure which was caused by the
excessive heat generated by the stalling of the rotor is not
considered a hazardous condition in view of the results,

wherein there was no expulsion of flame or molten metal,
nor ignition of the thermoplastic material or combustible
surface on which the mixer was placed during the test

"The flammability test was conducted on the complete
enclosure rather than on special test samples as specified by
ASTM, considering that the test if conducted on special
laboratory test specimens would not be truly representative
of actual conditions as might exist should the material be
subjected to a flame under some abnormal condition. The
results of the test show that the material can be ignited but
that once ignited the flame is quickly extinguished by flame
retardants added to the thermoplastic compounds. The
material can be classed as self-extinguishing on the basis
of the test results.

"Thermoplastic materials are not considered suitable for
the mounting of current carrying parts, or similar purposes
due to the possibility of displacement through distortion of
the material. The thermoplastic enclosure of this device
does not serve to support or mount current carrying parts
of the device and serves only to enclose the motor and other
functional parts of the device. The acceptance of thermo-
plastic material for the enclosure of this small motor-
operated appliance does not indicate the general acceptance
of this material for enclosing other electrical equipment."

Appearance, pleasant feel, light weight and heat and
electrical insulating qualities dictated the choice of a molded
phenolic housing in a new hair dryer in the Gilbert line,
and of a polystyrene handle in the Kitchen Kit mixer. Some
7" long and varying in thickness from l /%" to J^", this
handle weighs about ]/<*, Ib. It is a great convenience in
carrying the unit around as well as in maintaining position
during operation.

At this point, it would be well to call attention to a misuse
of plastics, as pointed out by Marshall Frisbie, chief engi-
neer at Gilbert's. When a molded phenolic housing was
first created to replace the die-cast metal housing of a mixer,
the motor and bearings were mounted in the plastics as they
had been in the metal. But it was found to be impossible
to do so satisfactorily with the close tolerances required in
all dimensions to secure proper fit at all points, and so the
plastics part was redesigned as an envelope, with the metal
having little or no anchorage in the plastics. With die-cast-
ing, the motor can be built directly into the housing, and so
does not have to be self-contained. This also makes for a
saving in parts. The same change was made in the com-
pany's hair dryer.

Plastics Has Sales Importance

The fact that the company was willing to go to all this
trouble to "save" the plastics, if only as a shell, is evidence
of its sales importance. For H. L. Trisch, vice-president
and sales manager of Gilbert's, makes much of the softness
and warmth of feel of plastics and of their durable finish.
Even though the Gilbert catalog does not refer to the
Whirlbeater housing as plastics, it does make the point
that the "smooth chip-resistant casing is styled for your
kitchen-of-tomorrow" and in the nine illustrations showing
the mixer's various uses, a hand is on it in every one.
Since the shell is literally the consumer's point of contact
with the device, its appeal is of the highest importance and
Mr. Trisch finds that it gives him a competitive advantage
in those instances where other companies do not use plastics
for the application.

Another early mistake in the use of plastics is one that all
beginners might make note of. In attempting to save mate-
rials, the walls of the thermoplastic part were molded so
thin that warping ensued. Another difficulty, however,
is to be laid at the door of the material supplier that is the
lack of uniformity in molding compounds previously re-
ferred to. While it is hardly the general rule, it does

appearance and texture of the natural or only slightly-less-
costly cultivated pearls are fairly well duplicated in notably
low-priced items with synthetic pearl-like surface coatings
on plastics cores.

The first material which proved satisfactory in the
manufacture of cores for synthetic pearls was glass. During
the war, when restricted importation made these hard to get,
manufacturers turned to such plastics as cellulose acetate
for replacement. Today, with the glass cores again obtain-
able, manufacturers indicate that they prefer to work with
plastics and no longer regard the latter as substitute mate-
rials. They are aware that a plastics core makes a better
simulated pearl and one which more nearly rivals its genuine
counterpart in richness and depth of lustre.

The Spencer Novelty Manufacturing Co., Brooklyn,
N. Y., makers of simulated pearls from both glass and
Lumarith plastics cores, has repeatedly emphasized the
superiority of the plastics-based bead to all its customers
which include chain, variety, jewelry and department store
buyers. Facts which indicate conclusively on a cash-on-the-

line basis that buyers actually offer better merchandise with
plastics are brought out in all of Spencer's dealings with
customers. For example, it is explained that plastics cores,
unlike glass, can be smooth-molded without any surface
blemishes and thus take an even coat of the pearl essence
covering, a result limited, however, to the cellulosics. With
Lumarith plastics-based simulated pearls the adhesion be-
tween the plastics and the coating forms a permanent bond.
Pearl coatings actually bite into cellulosic bases to become
part of the plastics core. The coating does not flake off to
leave any of the base exposed as so often is the case with
glass and other materials.

Another advantage cited by Spencer is that as the hole
in the center of the Lumarith core is produced at the same
time that the core itself is being made the diameter of the
hole can be controlled in uniformity to size and exact place-
ment in the center of each bead. This means that finished
beads hang evenly when strung. Furthermore, since the
plastics core is mass produced in this country as well as
being carefully controlled in its production, it is more to
be depended upon for deliveries than any import.

Making a Market

With these demonstrable facts as sales ammunition,
Spencer approached the S. H. Kress & Co., which had re-
quested from them a low-priced, glass-based simulated pearl.
Although Spencer was quite capable of supplying a glass-
based product, they felt that Kress would be making a mis-
take to stock it and outlined their reasons for advocating a
plastics-based bead. Kress agreed to submit a string of
Lumarith core simulated pearls to its company laboratory
for testing. The result was an overwhelming success for the
plastics-based bead on all counts. Kress immediately
switched its order from glass-based beads to those with
plastics cores.

As a follow-up, the Spencer people offered to supply

* THERMOPLASTIC INVENTORIES

<J SPI has issued its last list of surplus inventories.
With this series, the Society provided a sound service
for its members. Although the inventories are now at a
healthy low, several large surplus stocks are still not
liquidated. Until these are consumed, they will plague
the industry. They are evidently in the hands of non-;.
SPI members, to whom some outlet should be offered so
that they can list their surplus stocks and offer them to
the industry.

* ECONOMICS AGAIN

<I In February, the indices slipped away. Dragged by
the downward plunge of the commodities market, se-
curities dropped too, but in a more orderly fashion and
for no apparent reason. Most people agreed the stock
market had anticipated the drop a year and a half ago.
Even "Time" noted the bargains in industrial stocks in
relation to earnings. General agreement seems to be
that stocks will continue to be depressed moderately, but
that commodities should have been discounted a long
time ago.

<I The effect that this may have on the plastics business
will not be felt immediately. But in six months, lower
prices should yield lower-priced raw materials. Chem-
icals from fat, alcohol from grain, furfural from corn
and oats, can all stand realignment.
<I More important, the government immediately re-
corded a drop in the cost of living index. Percentage-
wise, that is small ; but cheaper food will do more to
keep plastics at relatively low price levels than any
other single factor. That is the surest way of raising
the earning power of the working man and avoiding
higher labor costs.

<I The sign posts of these past five weeks look good,
if general business is not frightened into a cubby hole
of fear and inaction.

* CONCERN FOR OIL

<J Our severe winter (estimated 12 colder than
normal) focused a concerned eye on the petroleum
industry. With 95 percent of the new railroad
engines built to utilize oil, and over 1,000,000 oil
burners installed in 1947, this concern is justified
and disturbing. Estimates for the first quarter of
1948 exceed consumption a year ago by 13 percent,
and the same period of 1941 by 85 percent. There-
has been a 400 percent jump in space heaters over
prewar, 27 percent in domestic central heating
over a year ago.

<I National resources are being consumed at in-
creasingly faster rates. Estimates of exhaustion
in ten to 200 years leaves the laymen cold to the
plea of long-term conservation. Perhaps ten is
too short, and 50 years is nearer. Regardless, any
useless exhaustion is inexcusable. The effect of
exhaustion of natural resources on our plastics
industry, to say nothing of the national economy,
is beyond comprehension.

<I Secretary Krug encountered a cool reception to
his proposal that the government embark on a
long-range program for the developments of oil
substitutes. Industry has already sunk millions
into these types of projects. One large plastics
chemical company is including research "for test
tube sources of oil" in lieu of petroleum in their
1948 program.

* SAVE OR SPEND

<I A one dollar bill buys today what 60^ bought
in 1939. That is a loss brought on by price in-
creases. Even the bond patriotically bought in
1943 would buy 25 percent less were it cashed to-,
day. The Conference Board points out that, coun-
try-wide, the 162 billion dollars saved personally
from 1939 to 1947 is only worth 124 billion, a loss
of 38 billion dollars. It pays to be thrifty in times
other than war, or with a spendthrift government.
<I The paradox is that with oppressive taxation
and labor dominance, there is little to attract risk
capital to investments in small enterprise^.

* SPE

<I The SPE symposium held in Detroit, January
22, was a success. The "anything but elaborate"
exhibitors' booths at the Rackham Memorial
proved to be both pleasant and beneficial, at least
from a sales point of view. With technical pro-
grams occupying the mornings, there was oppor-
tunity for general discussion of plastics problems.
This type of meeting is in keeping with SIM-'.
policy.

<I Mr. Harry DuBois, as the new president, lias a
difficult twelve months ahead. Fortunately, he is
well able to shoulder the many responsibilities of I
his new job. The respect and good wishes of the
entire industry are his.
fl It has been indicated that SPE may attempt a
closer definition of the term "plastics engineer."
If any individuals were excluded from joining

the organization could be weakened. It is im-
portant to have a membership of quantity, for no

A Chain Store

Products

Representing the largest retail market for
merchandise using plastics in the field of
toys, notions, handbags and costume jewelry,
chain stores and their buyers' viewpoints
are important to sponsors of plastics items.
The W. T. Grant Co., which has 486 outlets
in 39 states, is typical of large American
chain store organizations. A study of its ex-
perience in the buying and selling of items
utilizing plastics is therefore significant

MONG national retail outlets, the W. T. Grant chain
has gained a niche of its own. It has no upper price
limit on items handled and lines include so-called variety or
5 and 10(! store types. The original Grant outlet was a 25#
variety store; the price limit was raised to $1.00 during
World War I. A typical Grant outlet is in fact four stores
in one, comprising a dry goods store, a variety store, a
ready-to-wear store, and a home furnishing and hardware
store.

Grant's has done an outstanding job in the introduction
and promotion of plastics merchandise. This is no accident.
During the later war years when it became evident, at least
to some merchandisers, that plastics were to be important
in the post-war retailing picture, the company assigned an
executive to provide liaison with the plastics industry. In
the last year of the war he visited virtually every major
material supplier and established contact with many fab-
ricators and converters. With the information he gathered
and interpreted, he was able to make all Grant merchandise
buyers highly conscious of plastics and of their future
promises long before products incorporating plastics reached
the market in the immediate post-war period. By July
1945 a guide to plastics was prepared and distributed to
buyers, putting them in an excellent position to evaluate
merchandise, to induce better sales producing plans and to
aid in establishing sources of supply. Since then consulta-
tion on new items and problems has been provided on a
continuing basis.

The results are apparent in a survey of Grant operations.
This shows that the percentage of plastics merchandise has
risen to represent a significant part of total sales, and in
at least one line 90 percent of merchandise handled utilizes
plastics. Grant's has found that working with the industry

Serviceable and light weight, garment hangers of molded
plastics are a staple item in chain store merchandising

Most of the handbags now sold by Grant's are fabricated
from vinyl sheeting in a variety of styles and colors

Attractive household aprons made of vinyl are reason-

Toiletry items, as well as other plastics products sold
by the Grant stores, must have adequate serviceability

In merchandising of transparent plastics raincoats,
the eye-appeal of the product is fully emphasized

in its various ramifications has greatly increased sales and
profit possibilities.
These are significant aspects of the Grant surveys

1. The plastics industry has been literally unique
among American manufacturing groups in supplying
products at prices as low or lower than pre-war.

2. There has been a marked improvement in the
quality of merchandise offered by the Grant chain
during the last year.

3. There is plenty of room left for constructive
merchandising by plastics companies to expand fur-
ther the job being done through chain stores.

4. There is still a large amount of educational work
to be done among merchandise buyers in acquainting
them with plastics.

Like most aggressive merchandising organizations the
Grant company is vitally interested in seeing and having the
opportunity to buy new merchandise. Every department is
of course always driving to expand its sales and one way
to accomplish that aim is by the continuous introduction of
new consumer products. Within time limitations, buyers
at Grant's are willing and anxious to see new products and
to give them trial sale. A merchandise buyer however
does not necessarily follow the same standards of evalua-
tion on a product that would be used by someone in the
industry. His viewpoint is entirely conditioned by two
clear-cut questions :

One: Will it sell?

Two: Will it give adequate serviceability for the money?

The answer to the first question is determined by a rel-
atively simple process. An item which in the opinion of a
buyer stands a good chance of selling is presented by him
to a merchandising review committee which approves the
product and the merchandising plan suggested by the buyer.

At this stage no salesman is present and the manufac-
turer must rely on the product itself to tell its story and
display its virtues to the impartial merchandising group.
At these meetings the product is also reviewed from the
standpoint of serviceability. Often a very simple test is
sufficient. A comb that is not supposed to wilt in hot water
may, for instance, be dropped in hot water then and there.
If elaborate tests are indicated they are carried out by an
independent laboratory before approval or disapproval of
the committee is granted.

But the answer of the merchandising committee is not
supposed to be the final say on whether a product will sell
or not. A new item is usually first displayed in a limited
number of stores. Since every Grant location has an as-
sured traffic flow, the salability of a product can be deter-
mined very quickly by introducing it in a dozen or so stores,
giving it a good position in those stores, and watching the
sales results.

The final answer to the serviceability question comes
some time after the first introduction of an item. Grant's
has a policy of honoring all complaints and a report of each
is made to the appropriate buyer by the store manager. If
these complaints exceed what looks like a reasonable num-
ber the product is again evaluated and in some cases re-
moved from sale. It is significant that complaints on
plastics merchandise are as low or lower than for older
standard lines and that Grant has successfully avoided some
of the pitfalls that other merchandisers encountered during
18 months that followed the end of the war.

Grant's is a mass market selling organization. It is al-
ways concerned with low prices, commensurate with quality.
Products that sell well on Fifth Avenue are not of interest
in Grant's until the price is such that the average housewife
can afford to buy it. Grant's, therefore, is not interested
in items merely because they are new, but they quickly
become interested when they can foresee mass distribution.

The reactions to plastics on the part of the key buyers in
the company vary considerably depending on the type of
merchandise sold and the experiences of the particular

Smart packaging adds to merchandising appeal of toy
tea sets, which are molded in bright, eye-catching colors

A carefully planned display is designed to accent out-
standing qualities of covers for food, bowls, appliances

buyers. It is noticeable too that over a period of two years
the attitudes of these buyers have changed considerably
and are today much more favorable than before.

George A. Orr who is responsible for buying house fur-
nishings and housewares is markedly enthusiastic about
plastics in his field. "The plastics industry has finally found
itself," says Mr. Orr. Two years ago he would have ex-
pressed considerable dissatisfaction with the industry be-
cause of what he considered high prices and indifferent
quality. However, greater availability of materials and
more careful methods of fabricating reflect themselves in
much higher quality merchandise being available to Mr.
Orr, and a concurrent reduction in prices. Unlike mer-
chandise made of steel, ceramics, textiles or wood, the prices
of plastics housewares have gone down during the last year.
Even if they had stayed the same they would be in a rel-
atively favorable price position.

Products Have Proved Salability

Orr is particularly happy about the fact that the last year
has brought a procession of new items with genuine utility
and proved salability. An illustration, though, of the de-
cisions that must be made in line with Grant's basic policy
is the case of flexible, polyethylene kitchen bowls. Orr
looks upon these as a genuinely useful and unique contribu-
tion of plastics but the price is still too high to permit gen-
eral distribution. One disadvantage of some molded items,
as pointed out by Mr. Orr, is their tendency to collect
dust when displayed. In light colored items this gives a
shopworn appearance after only a few days on the counter.
Orr would like to see some way of avoiding this difficulty
that would not increase the cost of the product. In the
meantime, some items he is handling are being packed in
cellophane which enables the maintenance of a fresh and
clean appearance.

Of all the departments of the store in which plastics have

STAINLESS STEEL

FLATWARE

-#21*

Stainless steel flatware with handles of smooth, lustrous
plastics has color and durability for kitchen or dinette

come closest to "taking over" an entire line is that of hand-
bags. Most handbags now sold by Grant's are fabricated
from vinyl sheeting, replacing cheap leather and, to some
extent, fabrics. The most popular style is black patent,
definitely superior in durability to the original and markedly
lower in price. More recently calf finishes of outstanding
attractiveness have been developed, further expanding the
possible market.

Vinyl for Handbags

The company still finds it necessary, in order to meet
residual consumer preferences, to stock genuine leather
bags, but because of higher price and lower quality, use of
leather has greatly .diminished. Continued domination by
vinyl in this field will depend to some extent on style.
From time to time a shift toward fabric bags occurs. Even
this trend, if it develops farther, may not have too marked
an effect because it is now possible to duplicate the appear-
ance of a fabric bag in vinyl.

Mrs. B. Baker, buyer of handbags, points out that,
"plastics bags are particularly suited to chain store selling
methods. Merchandise is not displayed in glass cases but
is simply put out on the counter where virtually every
customer handles it." With some materials frequent mark-
downs result. Plastics bags retain their freshness even
when handled by many harried shoppers.

P. I. Freund is very enthusiastic about plastics in toys.
Here there has been a sharp change of attitude during the
last two years. The succession of new items introduced
since the end of the war by plastics molders and fabricators
and the success on retail counters has made plastics an
indispensable part of toy merchandising. Freund points
out, though, that successful "plastics items are still limited to
relatively small items," and feels that "future development
will lie largely in combinations of plastics molding with steel
or other metals," which will give greater freedom of design

MARCH 1948

PLASTICS

Colorful grouping directs attention to shower curtains
and window draperies of vinyl film. (Upper) Sale of this
material by the yard is facilitated by merchandising dis-
play of household items which can be made at home

and extend size limits. He feels that the success that molded
polystyrene toy furniture has met can be duplicated in larger
items if they can be given the necessary strength and dura-
bility. Freund confirms the experiences of other buyers in
reporting that quality has definitely improved and prices
are favorable in relation to those applying to other materials.
In electrical goods, other than appliances, handled by
H. G. Nichol and J. P. Ballock, molded phenolics and ureas
have been in use for years. Likewise cellulose acetate sheet
has attained full acceptance in lampshades, despite a cost '
differential over paper parchment. Mr. Nichol. though, is
somewhat cautious about predicting expanded use. He is
watching with interest, for instance, the development of
"all plastics" molded replacement sockets, where brass and
ceramic bodies have been standard. The molded type is
lighter than these and more compact in design, which may
mitigate against any immediate acceptance. Grant's also
insists on Underwriters' Laboratories approval on all wiring
devices handled. Such approval has been given to urea and
phenolics, but some thermoplastic products in this field have
met with more difficulty, because of the Underwriters' cau-
tion on flame resistance.

Polystyrene Lampshades

This difficulty does not arise with molded polystyrene
lampshades, which the company is stocking and selling in
all stores. Mr. Nichol does not see these shades replacing
cellulose acetate sheet or other materials, though, because
of the lack of flexibility in design. With ordinary methods,
a new lampshade style can be created and put into produc-
tion with very little initial investment. The cost of molds
for a plastics shade limits this freedom and tends to make
molded designs relatively simple. Nichol feels that greater
decorative value is necessary.

A case where plastics are suffering from at least a tem-
porary swing in consumer preference is in toilet goods.
Plastics lipstick cases and compacts were made and sold in
large volume during the war. Because of materials diffi-
culties these were Jiot generally of the best quality, and a
marked consumer prejudice was set up. Part of this preju-
dice arose from the hunger for metal compacts which were
temporarily unavailable. As a result, there are practically no
lipstick cases or compacts now being sold by Grant's other
than in metal. In part this is an example of plastics, the
glamour material, being outglamourized by a competitor.
It is not a price question since compacts have spiraled up-
ward in price since the beginning of the war.

W. G. Miller, toilet goods buyer, feels that an inex-
pensive plastics goods compact would not sell now but looks
to the time when an aggressive merchandising and restyling
job can induce a fashion trend back to plastics. It is sig-
nificant that the prejudices against plastics in this category
have not been projected to other items carried by Grant's.

Mr. Miller points out that plastics containers for facial
tissues and plastics powder puff boxes are gaining in popu-
larity.

Plastics Jewelry Sells Well

A related line, jewelry, has not run into the same diffi-
culty. Costume jewelry of plastics or combinations of
plastics and metal is selling well and expanded sales are
expected as new items are introduced. The color, gloss
and general attractiveness of plastics jewelry makes them
basic in any merchandising picture. Mrs. F. L. Kane, who
buys jewelry for Grant's, reports particularly satisfactory
results with metal plated plastics. Some extremely interest
ing effects have been worked out using this process and she
reports that the quality of the work is notably satisfac-
tory. Some of the early metal plated jewelry had a tendency
to peel and crack but this difficulty has been completely
overcome.

What's Ahead In Industry Uses

Field reports to the Editors of Plastics reveal in advance many planned or changed uses of
plastics by those responsible for the development of complete products of various kinds. That
readers may be so informed of such in-the-making events, a specially assigned group of
reporters each month contacts end users, research men, laboratories and key executives in a
number of cities.

Several leading lampshade manufacturers are looking very sharply at the development of
Injection molded shades. One firm, long the leade-r In lampshades fabricated from cellulose
acetate sheet, has a project under way which points toward a new line of molded polystyrene.
Not long ago lampshade makers pooh-poohed the possibilities here but several companies In the
plastics Industry went ahead on their own with efforts that met some real sales success. Some-
thing to watch. You can count, however, on continued growth of acetate In this field, largely
because of the great flexibility In design that It allows. Molded lampshades are likely to be
most Important In chain store lines, where large quantities of more ,or less "standard" designs
can be sold.

The use of vinyl coated paper fibers In auto seat covers, long discussed by plastics men,
seems to be moving closer to commercial exploitation. One of the largest producers of twisted
paper seat cover cloth Is actively at work on a vinyl coated line, which would sell at a pre-
mium over the present product, because of greater water and sunlight resistance, Improved dura-
bility and richer, more beautiful color.

Acrylic continues to move Into the advertising sign business. One manufacturer Is now In
commercial production of a unit seven by five feet. Even larger commercially made signs are In

areas than of technical know-how or do-ablllty.

There has long been a latent market for microscopes selling In the price bracket between
cheap toys and the high priced, high precision, laboratory types. One smart producer thinks he
has the answer through the use of molded phenolic parts, which can be produced with a high de-
gree of precision, yet at a cost level that will put the complete Job within the reach of hob-
byists, occasional users and schools. If he gets the volume, he can realize upon production
economies.

Watch for a spurt In the use of Injection molded handles on hand saws and similar hardware
units. There Is one Important manufacturer who Introduced a molded handle more than ten years
ago, only to drop It later on, who Is back on the track again. Ethyl-cellulose Is the material

by lumber people, because It was a replacement of their pet material wood of course.

A midwest concern making replacement parts for sale through service stations has been
looking for a method to package its wares in plastics. They're sold on the advantages but

Silicone Products
Hit the Counters

"Bouncing puffy" is used in furniture leveling
device. Golf enthusiasts will favor new golf
balls with silicone rubber center; the same
material makes up pad for handling hot dishes.
Silicone water repellent treatment for fish-
ing lines and flies is available; while silicone-
impregnated tissue is a good lens cleaner

SEVERAL TYPES OF SILICONES have found their
way into five products recently developed for the con-
sumer. Until now, exploitation of this young member of the
plastics family has been most intensive in the field of
industrial applications (Plastics, December, 1947), but
these new items, using Dow-Corning and General Electric
silicone compounds, are creating the opening wedge in mer-
chandise for retail counter point-of-sale.

The resilient type of silicone rubber popularly known as
"bouncing putty" has been incorporated into a device for
leveling furniture by Blake Industries, Detroit. Placed
under the leg of table, chair, piano and the like, the
Levelmalic, as the device is called, adjusts the object to
uneven floor coverings. The General Electric silicone is
contained in a simple cylinder and piston arrangement.

Resilient type of silicone rubber is used in device for lev-
eling furniture. Accommodating itself to variations up to
3/16", device has cylinder and piston which contain silicone

Taffy-like silicone, which has better bouncing qualities
than natural rubber, is put inside a rubber core of the
new golf ball, after which it is wound with rubber thread

Being elastic, it acts as a very viscous liquid would in a
hydraulic device.

In its present form, the Levclmatic can accommodate
itself to variations up to 9i", and it is claimed to last in-
definitely. Its capacity to stand up under such a heavy
weight as a piano is explained by its forming a metal to
metal contact when fully compressed.

The same General Electric elastomeric silicone rubber is
being used in the new Royal golf ball produced by the
United States Rubber Company. Employed as a pellet inside
the rubber core, it is said to give the balls greater "flying
power," and a newly developed electronic thread winding
device is claimed to be responsible for improved uniformity
in their playing performance. Already on the market in
Florida and California, U. S. Rubber plans to have the ball
available in other parts of the country in time for the golf
season. Like the previous Royal type, the silicone-centered
ball sells for 9Sc.

Used in Fishing Lines and Flies

Dow Corning silicones have been used for some time in
the production of a waterproof and water repellent treatment
for fishing lines and flies. These two products are called
Hy-Linc and Hy-Fly, respectively. Made by Scientific An-
glers Inc., they are marketed by B. F. Gladding and Co., Inc.
of South Otselic, N.Y. One application of Hy-Fly makes a
trout or bass fly permanently water repellent, and enables it
to float high and dry on the surface of the water, while one
application of Hy-Line keeps the line dry throughout an
entire day.

Two consumer products are being offered for sale by Dow
Corning Corporation. One of these is a lens cleaning
tissue, called Sight Savers, for spectacles or other optical
lenses. The other is an item for handling hot dishes safely
in the kitchen.

PLASTICS

MARCH 1948

Lense Cleaning Tissue

Sight Savers are attractive small booklets of papers im-
pregnated with a silicone fluid. When the tissue is rubbed
lightly over the lenses, it not only cleans them, but also fills
in minute scratches, thus improving the clarity of the
glasses. A fine residual film of silicone is said to remain.
This protects the glasses from dust and moisture, and allows
any subsequent dirt to be easily removed with the new
Si i] lit Savers.

In order to find out what the public reaction would be to
this item, Dow Corning made a marketing test in a drug
chain in western New York. They wanted to find out, first,
whether the public would be willing to buy such eyeglass
cleaners at all, for people have been accustomed to using the
cloth wipers provided by opticians, tissue paper, or a
handkerchief. Granted that they would buy a special prod-
uct for this purpose, the company wanted to learn how
customers reacted to the different types of packages that
were offered them.

Results showed that the silicone-treated tissues were ac-
cepted by many eyeglass wearers. As a result of the test,
it was concluded that the booklets of silicone-treated tissues
could be sold in quantity, provided they were packaged and
promoted properly.

Good Packaging Display

Accordingly, the Sight Saver booklet was designed with
an attractive cover of Ethocel film. The design was made by
Don Wagnitz of Midland, Michigan, while the printing
was done by The Dobeckmun Company located in Cleve-
land, Ohio.

An attractive counter display was designed that is essen-
tially an enlargement of the package. To show the thin
little packages to advantage on counters, a display box was
made up which contains four dozen Sight Savers, and in-
cludes a demonstration pad for use by the sales people in
the store. The display box consists of a brightly printed
background with cellulose acetate film laminated over the
printing to add to its attractiveness, and to raise the quality
of the display box up to that of the booklet cover.

In September, the Chicago area was chosen as the first
tryout market for the final product. It was advertised
in three of the city's newspapers and on posters on the "L"
and subway lines, as well as the commuters' Illinois Central
stations. The sales response was so good that 100 jobbers
are now handling the item in leading midwestern cities,
distributing them through the drug chains, with department
stores and optical firms listed as the next outlets to be
opened up.

Heaf-Proof Silicone Rubber Pad

Dow Corning Corporation has also produced a Silastic
silicone rubber pad for handling hot dishes, pots, canning
jars, sterilized baby things, and the like. It is advertised as
heat-proof (up to 500 F), steam-proof, slip-proof, grease-
proof and scorch-proof. Easily cleaned with soap and water,
the holder stays new looking indefinitely. Although not
featured as such, there is no reason why the pads cannot
also be used on tables to hold hot plates, casseroles, etc.

For decorative effect, stripes of colored silicone are
worked across the surface of the white body. A pair of the
holders is neatly packaged in a rigid envelope of Ethocel
ethyl cellulose, making it an attractive and desirable gift
item.

At present, Marshall Field & Company, Chicago, is the
main retail outlet for Grip-mitt. This item was placed on
stile there about three months before Christmas, and a sub-
stantial volume developed during the Christmas season.
Gripmitts are available from Marshall Field's at $1.95 per
pair, and are being featured by them currently in a direct

on fishing flies will enable a trout or bass fly to float
high and dry on the surface of the water for an entire day

A silicone rubber pad for handling hot dishes is claimed to
be heat-proof, steam-proof and scorch-proof. It is easily
cleaned with soap and water, stays new looking indefinitely.
Stripes of colored silicone are worked across the surface
of the white body, for decorative effect. A pair of the
holders is neatly packaged in a rigid envelope of ethyl
cellulose, thus making an attractive and desirable gift

A consumer item which has met with popular acceptance is
a silicone-fluid-impregnated cleaning tissue. When tissue
is rubbed lightly over the lenses, it not only cleans them
but also fills in minute scratches, thus improving the
clarity of the glasses. A fine residual film of silicone
is said to remain, which protects the glasses from dust
and moisture, allows subsequent dirt to be easily removed.
Tissues are packaged in an ethyl cellulose covered booklet

How the Promoting Marketer
Broadens the Use of Plastics

Something new. something dynomic, has been
added to the important groups of the plastics
industry. There enters the Promoting Marketer
who contributes to progress, yet makes use of
afready established facilities and services

NEED FOR creative merchandising has produced a new
class of business enterprise in the plastics industry that
of the Promoting Marketer. The functions served are well
known but the name is new. Thus, the job itself may be done
by sales agents or even by manufacturers. Actually, Promoting
Marketers are neither promoters nor marketers. They do,
however, assume full responsibility and virtually all the risks
in the creation, development, introduction and sale of a consumer
product made entirely or mostly- of plastics, but use the facilities
of custom molders or fabricators for 'actual production and
for much of the required engineering.

The function of the promoting marketer came into existence
with the introduction of fabricated vinyl film goods before the
war. When thin-gage vinyl films became available, there was
no established industry to handle them. Individuals and firms
who saw the marketing possibilities of these materials, but who
did not wish to become manufacturers, arranged for plants to
fabricate the film on a custom basis, retaining all the marketing
functions in their own hands.

The advantages of this arrangement were apparent. The prin-
cipal was relieved of the problems of setting up manufacturing
facilities and the manufacturer did not have to concern himself
with selling into unfamiliar markets.

The pattern established in the vinyl field is still widely fol-
lowed there, and was quickly picked up in injection molding.
Lately there is evidence that the same type of operation is be-
coming more important in compression molding.

Promoting marketers begin their operations with the con-
ception of a new product, or the modification of an old one,
that appears to be feasible in molded or fabricated plastics. The
initial conception is usually checked by market exploration in-
volving contact with a few department store and chain store
buyers. The promoting marketer then consults with a custom
molder or fabricator on choice of materials, detailed design of
parts, and on mold building. At this stage, too, an industrial
designer may be engaged by the marketer to develop a design,
in consultation with the molder.

The next step is the production of samples. Often, in the
case of an entirely new article, a single-cavity or other low cost,
limited production mold is built. Samples made at this stage
are then shown to a limited number of buyers and their reaction
secured. If the response is good, construction is begun on a
production mold and any necessary accompanying tools. The
responsibility for the mold is usually but not always assumed
by the custom molder. If it is not made in his shop it is often
made under his supervision in an outside shop and the molder
takes responsibility for proper functioning. In other cases the
mold is built by an independent mold maker and the promoting

ded Tenite

INTERLOCKING Tenile strips make attractive
slide-away doors for kitchen cabinets. The lightweight .

panels glide up and out of the way at a touch, providing
maximum entry to cupboards. Good dimensional stability
of Tenite assures smooth operation.

Dust and grease are easily cleaned from lustrous Tenite surfaces
with a damp cloth. Tenite color never needs refinishing, since it's
peelproof. Tenite is extremely tough and can withstand hard use.

Tenite utility and beauty are featured in many other articles
of household equipment among them, telephones, toilet seats,
kitchen utensils, bathroom fixtures, and nursery furniture.
For other uses, and a complete picture of Tenite properties,

S P I Hotels Annual
LOW-PRESSURE SESSIONS

Technical papers allied with Jow-pressure molding materials and methods of
fabrication were presented in generous diversity at the Third Annual Low
Pressure Meeting of the Society of the Plastics Industry. An accompanying
exhibit served to highly dramatize the various accomplishments of the group

LOW-PRESSURE INDUSTRIES DIV. meetings of
the Society of the Plastics Industry, Inc., held as the
Third Annual Technical Session and Exhibit at the Edge-
water Beach Hotel, Chicago, on January IS and 16, attracted
195 persons representing 110 member companies. This was
higher than the registration of the two previous annual. meet-
ings, and although the division is not gaining new member-
ship rapidly, it is reaching out to those men and companies
who actively participate in the sessions.

A wide variety of low pressure molded products was on
display, showing what the industry has accomplished in the
past eight years. These included the plastics paneled in-
terior of a modified De Soto station wagon, sink tops, cases
and luggage, piping, industrial applications, fishing rods,
golf club heads and railroad chair components.

The Division is polling its members on the question of
changing its name to Reinforced Plastics Div., which seems
to be favored above the present designation.

Summaries of SPI Papers

Summaries of the papers presented follow :

W. Burdette Wilkins, Consultant, Ridgewood, N. J.,
"Economics of Reinforced Plastics": discussed cost fac-
tors of various low-pressure molding techniques, based on
an outline published in Plastics (July, 1945). Among the
types of articles which do not at the moment lend themselves
to low-pressure molding, he listed: (1) Any articles in
which the volume of production is sufficient to warrant the
expense of precision dies, such as auto fenders, tops, boats,
hoods, etc. (2) Any article which is simple enough in
shape to be fabricated on existing standard machines. (3)
Any article that is small enough to be handled with high-
pressure molding techniques and with quantity sufficient to
warrant die costs, such as small radio cabinets. (4) Any
article where accurate tolerance must be controlled and
accurate thickness must be maintained throughout the
structure.

Among the products that can be successfully fabricated
by low-pressure molding in combination with other mate-
rials and techniques, he enumerated articles of large size
produced in small .quantities, articles of moderate size with
a multiplicity of compound curves, articles in which high
strength and low weight are predominating factors ; articles
subject to severe weathering conditions and corrosion; large
articles in which dielectric efficiency is important.

D. G. Patterson, American Cyanamid Co., and Dr. J.
D. Robinson, "Developments in Catalysis and Process-
ing of Polyester Resins" : pointed out that the cure cycle
of a polyester resin appears to consist of at least four signifi-
cant stages: (1) An Induction Period or gel time, when
the resin is heated before any noticeable reactions takes
place. This is determined by the reactivity of the resin,
the inhibitor, concentration and type of catalyst used and

the temperature of the resin system. (2) The Initiation of
the Exothermic Reaction. (3) Peak Temperature of Reac-
tion. A high peak exotherm is necessary for a fast cure,
but must be combined with a moderate initiation tempera-
ture to insure good quality. (4) Reduction of Temperature
Following Climax of Reaction.

Dr. H. L. Gerhart, Pittsburgh Plate Glass Co., "New
Developments in Polyester Resins" : detailed the improve-
ments achieved in polyester resins with respect to stability,
cure time, color, impact strength and heat distortion temp-
erature. It was noted that, as to fire hazards, self-extin-
guishing resins have also been produced.

Arthur L. Smith, Resinous Products & Chemical Co.,
"New Developments in Treating Cellulose Fibers for
Polyester Laminates" : presented data on a material for use
with cellulosic fillers to increase their resistance to moisture
absorption in polyester laminates. This technique involves
the use of an aqueous solution of a low molecular weight
urea formaldehyde condensation product. A 5 to 10%
solids solution was used to impregnate cotton duck to a
resin content of 8 to 10% of the total weight. This pre-
treated cotton duck was then saturated with a polyester
resin and cured in a laminating press at 50 psi pressure at
250 F. The water resistance of these laminates was found
to be equal to that of phenolic grade CE laminates.

George R. Wallace, Decotone Products Div., Fitch-
burg Paper Co., "Designed-Printed Papers for the Poly-
ester Resin Laminated Industry": Better papers for the
production of decorative laminates of the polyester type
have been made by gravure printing on relatively rigid
papers. The surface of the paper must be such that all the
engraved cells in the gravure printing roll come in contact
with it during the printing procedure. New inks have
been developed which will not fade or bleed, though the
laminator is advised to run a small sample in production
to see if his operating procedure will permit the use of the
ink without bleeding. It may be worth limiting the amount,
of styrene monomer in the interest of producing an attrac-
tive design, even though the cost is higher.

Cecil Armstrong, Plastics Consultant, Armstrong Plas-
tics Co., "Continuous Laminating" : Filler materials suit-
able for this process are paper, cotton rayon and glass fibers ;
cotton, rayon, and -glass fiber bonded mats; aluminum foil
bonded paper. These filler materials may be impregnated \
with a polyester resin, either in a continuous impregnating- .
laminating unit or a separate impregnating unit. The former j
permits straight line production and saves labor costs. The!
separate impregnating unit permits use of denser, less ab-
sorbent filler materials because long soaking times may be
permitted and requires a smaller number of resin pans. j
Mr. Armstrong also discussed the factors affecting pro-
duction rate.

SOMETHING NEW IN SIGNS... DU PONT "LUCITE"

Distinctive by day . . . bright by night. .. built to last . . . colorful and light

HEARING COMPLETION, the lustrous
sign face of "Lucite" shown above
is getting a "touch-up" buffing.
Readily machined and formed,
blanked and cemented, "Lucite"
can be used to produce unusual
combinations and effects. Skilled
fabricators throughout the country
are taking advantage of the quali-
ties of this plastic in the manu-
facture of hundreds of products.

Glowing like a huge light globe . . .
bright and eye-catching, day or night
. . .here's an outdoor sign with "pull-
ing" power. It's new! And it's sign
news. It's made with faces of brightly
colored, translucent "Lucite" acrylic
resin.

"Lucite" captures sunlight and dif-
fuses it over both surfaces of the sign.
At night the whole sign glows evenly-
lighted from within. In sunlight or
darkness "Lucite" boosts visibility . . .
and arrests attention.

More and more manufacturers are
turning to "Lucite." Available in many
colors or crystal clear, it is readily fabri-
cated or molded. It resists weathering
and does not shatter. It needs no paint-
ing, and maintenance is minimized.

Write for free booklet, describing
"Lucite" and other Du Pont plastics.

SPE He views Progress
at Detroit Conference

SUMMARIZATION of technical progress in materials
and molding and fabricating procedures was effectively
accomplished in the 17 papers presented at the Fourth
National Conference of the Society of Plastics Engineers,
Inc. The meeting was held in Detroit, January 21-23, in the
Rackham Memorial Bldg. and covered such topics as the
satisfying of consumer demands ; the use of plastics in the
automotive industry; the industrial applications of molded
nylon, polystyrene and the latter's copolymers; plasticizers ;
fabrication and molding techniques and color standardiza-
tion work.

While these papers were presented at the morning ses-
sions, the afternoons were given over to conferences in the
Banquet Hall, where 23 booths were set up by materials,
equipment and other companies with a stake in the plastics
industry. This was an innovation for the society, replacing
a general show for the public given in previous years. Al-
though there were dissenting voices, the general verdict of
the participants was that it was a good thing. The booths
provided a convenient meeting place for engineers and com-
pany representatives to talk over specific problems, it was
said. The most enthusiastic endorsement was given by a
company which introduced a new material, on which in-
quiries and orders were reported as substantial.

Registration for the conference came to 360, of whom 267
were members representing SPE sections throughout the
country.

Officers for 1948 named at the conference were : president,
J. H. DuBois, Shaw Insulator Company; vice-president,
Mario Petretti, Noma Electric Corp. (Springfield, Mass.) ;
secretary, R. G. Dailey, Wolverine Plastics; treasurer,
R. B. Bishop, Socony-Vacuum Oil Company.

Abstracts of papers delivered at the meeting follow :

P. S. Olmstcad, Bell Telephone Laboratories, Inc.,
"The Consumer Looks for Quality": With a buyer's
market in prospect, the consumer will be more inquisitive
about the relative qualities of competing products. This
more critical attitude will be associated with wants that are
both more extensive and more specific. It is a primary
problem for the engineer to design and produce products

that will satisfy such wants. It is also important that his
procedures provide economic control of quality. This paper
reviewed pertinent engineering developments in this field
and outlined a way of making it possible to attain such
economic control.

W. M. Phillips, Research Laboratories Div., General
Motors Corp., "Plastics in the Automotive Industry":
First used more than a quarter-century ago, plastics have
increased in importance to such a degree that about 100
plastics parts are now used in the average automobile, with
a total weight of about 5 Ib. The kinds of plastics are dis-
tributed as follows: Phenolics 1.3636 Ib, Cellulose acetate
and/or butyrate .8698 Ib, Cellulose nitrate .0389 Ib, Methyl
methacrylate .6095 Ib, Polyvinyl chloride 1.2670 Ib, Urea
formaldehyde .0265 Ib.

Plastics materials will be used in 1948 to about the same
degree. Some kinds have replaced others and there is a
lot of competition developing, with vinyls and polystyrenes
getting into a better position. Nylons and other plastics
have improved their chances of use in upholstery. Plastics
envelopes in stamping are commencing to look promising.
Certain laminates are coming on and may replace some
steel parts. The writer is bullish on the prospects for the
use of plastics in the long-term view of the automotive
industry.

J. E. Teagarden, E. I. du Pont de Nemours & Co., Inc.,
"Nylon as an Industrial Plastics": This material is bo-
coming increasingly important in engineering planning.
Available in a number of formulations designed to meet
specialized requirements in injection, compression and ex-
trusion molding and solution coating, nylon has very un-
usual properties which recommend its use where conven-
tional thermo-plastics and some thermosetting materials are
unsatisfactory. Techniques for making articles of nylon are
but slightly different from those used for other plastics.
Modifications necessary to mold or extrude nylon in con-
ventional equipment were discussed in this paper.

Applications for nylon include impact tools, gears, bear-
ings, machine parts, sterilizable items in the medical and

PLASTICS

Removing air from polyvinol alcohol bag so ordinary air pres-
sure, pushing bag against "Fiberglas," sets plies more firmly

dummy. Three or four, usually four, depending' upon the
desired thickness of the duct, layers of the cloth are wound
around the model. Ends where the duct will form a con-
nection are reinforced with additional layers. The red lac-
quer serves as a guide in judging the number of thicknesses
of Fiberglas by the brightness of the red showing through
the "bandages," eliminating the possibility of a weak spot
appearing in the duct.

The next step in converting the soft Fiberglas wrappings
into a rigidly strong plastics duct is to put them into an oven
and bake them. The entire assembly is placed in an airtight
cellophane-like bag made of polyvinol alcohol and the air
is pumped from the bag to form a vacuum within it so that
ordinary air pressure, ten to 12 psi, presses the plies of
Fiberglas tightly together during the baking process, form-
ing a stronger bond than would ordinarily be possible.

Baking is done at 200 to 250 F, a temperature which
quickly starts chemical reaction in the resin and creates a
hard-set plastics. The resin, a contact type, does not boil
during its change from a liquid to a solid. Baking takes
from one to one-and-a-half hours. Upon removal from
the oven, the mandrel is broken with chisels and hammers
and the pieces fall through an open end of the duct. The
lacquer coating serves its second purpose here in pre-
venting the plaster mandrel from adhering to the plastics
duct. The duct is now ready for installation in the air-
plane's air-conditioning or anti-icing system. Any damages
that may occur to the duct in the future are repaired easily
with use of an infra-red lamp or electric heating element,
without removing the duct from its place in the airplane.

From the standpoint of design, the use of plastics permits
a more efficient ducting system. Because the ducts can be
made in virtually any shape, the designer does not have to
take into consideration the manufacturing problems that are
involved in making metal parts. Savins' of engineering 1
time in design freedom is a valuable by-product, of course.

There are savings, too, on the manufacturing end. Cost
analyses indicate that the plastics ducts are more economical
than metal ones for various quantities up to 500 ducts of
one type, depending upon complexity of the metal counter-
parts. This is a matter chiefly of reducing tooling expense,
and the more complicated the duct, the greater comparative
saving in costs of both tooling and fabrication. The use of
plastics eliminates dies and welding and considerably de-
creases trimming and drilling costs. Ducts are strong and
can carry pressure up to 25 psi without serious distortion.

The ducts are being made in Boeing's Seattle plant and at
Vichita, Kas., under contract with Swallow Aircraft. END

Plastics Cores for Better Pearls

(Continued jrom page 17)

Kress with counter cards for their chain stores throughout
the country. These gave an at-a-glance story of the process
of making plastics-based simulated pearls. Kress, now
thoroughly in back of the plastics-based product, was fully
in accord with this suggestion, seeing in it a means of
acquainting its sales personnel with the merchandise
handled. Counter cards were sent out to all store managers
with a covering letter asking that the posters be given to
sales personnel for their information and when advisable
to be used on counters or in window displays. Kress reports
that response was enthusiastic, not only on the part of;
employees but store customers.

Other stores enthusiastically promoting plastics-based
simulated pearls include the W. T. Grant chain. Here, Mrs.
Fay Kane, jewelry buyer for this store, feels that customers
get better value for their money when they invest in a
plastics-based necklace because of the beads' uniformity
and lightweight appeal. And, in addition, according to Mrs.
Kane, shipments of plastics-based beads come through
quicker. This is important for a chain store that does such
a large volume of business.

/advantages of P/asf ics-Based Necklaces

Department store buyers, too, recognize the advantages
of plastics bases. Miss Helen Maicox, jewelry buyer for
Oppenheim Collins & Co. was one of the first buyers in
the country to stock plastics-based necklaces. She has pio-
neered the style trend of the large bead chokers purely
through her early acceptance and belief in plastics bases
with their characteristic light weight. Especially enthusi;istic
about this quality, Miss Maicox believes that although glass-
based beads may tend to drape better in the hand, the final
test is in the wearing and plastics-based simulated pearls
assure comfort as well as style.

This kind of conscious promotion on the part of both
manufacturers and retailers of the positive merits of the
plastics-based product certainly paves the way to a wider
consumer acceptance. It is reasonable to assume that other
manufacturers and retailers are likely to follow the example
of Spencer and the retailers mentioned herein by using
plastics cores as a part of their simulated pearl promotion
story.

die toward bright, solid color has been taking place in the
last few months. Curiously enough, the trend is doniinantly
toward red. Women, who, by the thousands, learned to
handle tools during the war, have had no small influence on
this development. But entirely aside from that, the hard-
ware retailer has noticed that the mechanic himself re-
sponds to plastics color in making his purchases today.

From the functional viewpoint, an even more potent re-
cent development in tool design is the hollow magazine
handle of plastics for containing bits of various sorts which
may be chucked within a single tool. Hollow drill handles
of steel, of the type of the Yankee drill, are not new, of
course, but plastics handles of that type are. The new ver-
sion of the Yankee Handyman, a spiral ratchet tool which
chucks both screw driver and drill bits, has a magazine
handle molded of clear cellulose acetate. A magazine-han-
dled tool of a different function, just put on the market in a
brand new design, is the Millers Falls hand drill with crank
and end handles molded of red cellulose acetate butyrate.

The plastics is applied to both parts of the magazine han-
dle, the screw cap and the hollow barrel body that holds
standard twist drills. The functional design given to the
plastics handle has had its effect on the rest of the tool,
which has been streamlined by aligning the circumference
of the chuck with that of the shaft sleeve and combining the
crank handle with the gear cover.

Peck, Stowe & Wilcox, of Southington, Conn., have pat-
ent pending on a new brace and bit with ethyl cellulose han-
dles. That a very old firm like this one is using plastics for
the first time and achieving excellent response, is quite sig-
nificant.

Redesign of a whole line of tools for plastics is exem-
plified in the Hallowdl series of kit tools auto, socket
wrench, socket screw and home kits in all of which the
magazine handle is molded of ethyl cellulose in various solid
colors (Plastics, March, 1947). Altogether the applica-
tion of plastics to magazine handles for the chuck type of

to eliminate all intermediate handling

When you figure a job to the fraction-of-a-cent-per-finished-part, the
R9&&3PD gives you three all-important advantages. Because the ma-
chine performs all steps in a production cycle from powder to finished
part, in a fast, uninterrupted sequence . . . the costs resulting from the
numerous handling steps in conventional molding practice are com-
pletely eliminated. With the R1J&E3PD the only handling required is
the initial loading of the powder into the hopper and the removal of
the finished parts.

In addition, the RfJEMSPD cycle eliminates the need for preform
storage and thereby the losses from moisture absorption. And because
no more than an average of four cycles are ever in process at one
time, short or excess preforms due to powder variables are quickly
detected at minimum waste of materials. For all the facts about the

Two-piece construction of Bendix radio cabinets reveals
ingenious joining by use of splay-throated gate in mold

CONTINUED imaginative specification of plastics
materials in its radio cabinets is revealed in the two
most recently announced models of Bendix Radio Div.,
liendix Aviation Corp., Baltimore, Md. One has a Lustron
polystyrene housing; the other uses Plasleon urea formalde-
hyde, and both models, introduced to the public during the
year-end holiday season, "scored an initial sniccess both for
their novel treatment and beauty," according to J. L.
I. O'Connor, sales promotion manager of Bendix Radio.

From the plastics point of view, the model with the styrene
cabinet is of special interest since its two-tone construction
is a bold innovation for the material in this field and has
possibilities in other products as well.

There is another aspect of this design which 1m >
omewhftt negative angle but it points to a significant fact
that the industry must face : plastics materials in some cases
will have to compete with each other as well as with tradi-
tional materials. Thus, this new Bendix model is identical
in exterior styling with Model 526-C, which the company
marketed last year in another type of plastics housing. The
latter was strikingly attractive, had excellent sales appeal
and served its purpose for the manufacturer but it has
yielded now to the styrene partly because the latter is lighter,
lower priced and tougher and because it makes possible a
simplified production set-up as well. The new models' retail
for $29.95, which is now also the price of Model 526-C.

Made originally in four pieces, the housing is now injec-
tion molded in only two parts. These are designed to engage
each other by interior channels, and six screws complete
their attachment, on the vertical faces. The joining and
fastening are accomplished so that no seams are visible.

win approval by the company's engineers as well as the
Underwriters' Laboratories.

Available in a very wide range of colors and degrees of
transparency, a brown and a two-tone tan styrene were
chosen for Model 114, and maroon and wine and ivory mot-
tle for Model 115. In both models the base section is in solid
color while the top portion bears the color combinations.
The two-toned effect is gained by flowing the material into
the mold through a l^" gate above and behind the dial area.
The gate's splay throat produces a fan pattern of smooth
symmetry across the surface of the top.

The basic design of these models was conceived by J. F.
Glover, of the company's development department, who col-
laborated with the molders, Ideal Plastics Corporation,
Hollis, N. Y., in effecting the changeover in materials.
Ideal's study of the molding conditions required rounds out
the story of this development.

After approving the operational functions of the molds
and analyzing several test shots, it was obvious that two
distinct problems had to be overcome :

(1). A uniform and soft appearing mottle had to be
maintained. Although this would seem to be basically a
material problem, it became apparent that mold temperatures
affected the mottle shades. Trial runs were therefore set up
to observe the effects of heat and pressure on the mottles.
Comparing the data with the molded pieces, it was evident
that specific temperatures had to be maintained for the soft
shades specified by the manufacturer.

(2). Weld lines had to be made less apparent, or
entirely eliminated. Meeting this problem involved a con-
flict with the first problem, for when the temperatures were
varied to assist in the elimination of welds, the desired
mottle shades were spoiled in some cases. To add to the
"difficulties, the core side of the die had to be kept cooler than
the cavity side as the lock-out friction plus the deep draw
of the product created the tendency to bind the mold.

Additional test runs were made with temperature,
pressure, plunger speed and over-all cycle being recorded.
From these data, specific controls were put into effect for
the molding of the cabinet units.

Two Molds Run Simultaneously

The two molds are run simultaneously on individual
presses as the cycles are approximately the same. When
the products are removed from the presses, they are placed
-on a stock rack or at the head of the assembly line. They
are then buffed, assembled and packed all within a distance
of 25 ft of the two presses.

The second change made by Bendix was in a model sup-
plementing a previous design of a one-piece molded phenolic
cabinet with molded-in handle and all-enclosed back. While
specifying a brown mottle finish for the housing of a varia-
tion on this type (Model 111), still molded of phenol for-
maldehyde, Bendix also wished to have the same design in
a white finish. Although there are paints available com-
pounded with titanium which will give molded phenolic
a solid white coating, the manufacturer preferred to have a
scratch-proof molded-in color, which of course provides a
finer finish. For this it turned to Plaskon urea formalde-
hyde, specifying in ivory tone for Model 111-W.

The company also feels that this material, which is light
and strong as well as decorative, enhances another feature
of the instrument the "brite-lite" acrylic dial. This emits
a warm glow in semi-darkness which is brought out more
effectively by the glossy white of the urea.

Models 111 and 111-W are both molded by the American
Insulator Corporation, New Freedom, Pennsylvania. END

PLASTICS

A Permanent Tape for Tennis Courts

Extruded polyethylene has been introduced
to replace chalk and conventional types
of marking tape. It has been tried out and
found satisfactory by two leading eastern
tennis clubs. Some advantages of the new
tape are its resistance to abrasion, wafer,
weathering. Is fastened with copper nails

NOW IS THE TIME when all good tennis fiends be-
gin to think of the coming season. But their en-
thusiasm for the game does not extend to the court, if they
happen to own their own, for maintenance of a tennis court
is a headache. Keeping it clearly and cleanly marked is
one of the main nuisances. Chalk wears off quickly and can-
vas tapes crumple. A permanent tape is so desirable that
other materials have long been sought for the purpose, and
Anchor Plastics Company, Inc., New York, has come up
with a tape extruded from polyethylene suitable for both
private and public courts.

First performance tests of the new product, carried out
on the courts of two Eastern clubs, have given satisfactory
results, establishing its resistance to abrasion, water and
weathering properties already confirmed in so outstand-
ing an application of the material as co-axial cable covering.
Exposure to the baking summer sun was considered the
critical test in the tennis court application, and the poly-
ethylene tape passed this also. The reservation must be
made, however, that the material is likely to break down
under the strong ultra-violet rays of the sun, in such areas

Installation of Anchor Plastics polyethylene marking tape at
West Side Tennis Club, Forest Hills, New York, has met with
satisfied reception. Left, corner of new installation shows tape
fastened with copper nails. Alongside it is a roll of ex-
truded tape with holes punched out to receive the nails

as Arizona and southern California. In the temperate zone,
first field tests indicate that polyethylene tape will not em-
brittle or crack.

One installation was made last June at the West Side
Tennis Club, Forest Hills, New York, scene of interna-
tional championship matches. The polyethylene tape was
laid down on one of the courts used by club members. This
has a special surface layer of fine grit, which is finer than
the usual grade of clay. According to Derrick Atkinson,
manager of the club, the plastics tape was "very satisfac-
tory" and will probably be used on more of the special sur-
face courts this year.

Although Mr. Atkinson said that the white chalk con-
ventionally used was adequate for clay courts, other clubs,
and certainly individuals having tennis courts on their own
property, find it troublesome to keep remarking them, for
chalk lines along both the service line and base line are
pretty much trampled out in the course of a day's play.

Permanent Marker Necessary

That is why they have used a permanent marker such as
cloth tape, despite its deficiencies. A major fault of this
tape is that it is not permanent, but spoils over the winter.
That is why the polyethylene tape was tried out last spring
by the Manursing Island Tennis Club, Rye, New York. The
club grounds being near Long Island Sound, this provided
a further test of the resistance of the plastics to a salt water
atmosphere. On all counts, the new marking material was

NEW HEEL

"DME No. 2"

An improved steel now made available to you after many
years of extensive research by our engineering staff.
This new DME No. 2 Steel is, without question, the finest
steel obtainable anywhere for mold bases as well as for
cavities for plastic molds and zinc die-casting molds.

DME No. 2 is a medium carbon, oil hardening alloy steel
specially compounded for DME and heat treated for
maximum ease in machining consistent with extreme
hardness and toughness. The superiority of this steel is
amply proven by the fact that it will take over three
times the load of ordinary warehouse low carbon plate
without permanent deformation.

This steel is carried in stock at 225 Brinell. With further
heat treating its hardness can be increased to over 300
Brinell with very little or no loss in ease of machining.
Whenever extra hardness or toughness in mold bases or
mold parts is required, we recommend the use of DME

No. 2. You'll find it will more
than pay for itself in greatly
lowered mold maintenance'
costs.

Weight-Saving on Tableware
Sells Plastics to Airlines

Everyone seems to benefit when plastics dishes are used by
airlines. Companies like reduction in non-payload; hostess
has less weight-joggling to do; passengers enjoy lightness

ALTHOUGH nearly all the airlines use some plastics
dishes now and several use them exclusively, these
wares did not sell themselves. At first the airlines were
content with their disposable paper dishes and china, and
were not receptive to the new plastics products, according
to F. C. Meacham, who opened up this outlet for the North-
ern Industrial Chemical Company, Boston, Mass., which
has since become the major supplier in the field. Northern
dishes are in use on the Eastern, Colonial, Pan American,
TWA, American, Braniff, Alaska and other lines. From
a small business in 1939, it has grown steadily until today
Northern supplies a large part of all the plastics dishes used
by these carriers.

The airlines had their first intimation of popular interest

Plastics dishes, now extensively used on
most airlines, were not accepted until
proved that they materially reduced cost
of non-payload. Impact strength was also
a strong selling point, as were feel, ap-
pearance, cleanliness and washability

in plastics ware through their hostesses whose passengers
began to ask about them. When the purchasing agents
received these reports, they were interested, but they were
still far from sold. They were interested because the com-
panies were then particularly keen on making the public
air-minded and in making their service as pleasant as pos-
sible. Still, they knew that for most people all plastics were
wonderful and miraculous; to them, the plastics dishes
might be in that same fabulous category. However, initial
requests for them at least made the purchasing agents re-
ceptive to rational arguments on behalf of the new products,
and these Mr. Meacham was able to supply.

Lighr Weight fs Important Factor

The first and most potent sales point for plastics materials
was their light weight. In any number of applications, this
is a significant factor; in any component of an airplane
structure or load, weight is very nearly the most important
single factor, and when it is a question of non-payload, you
can take out the "very nearly," for obviously, any reduction
in load makes for lower operating costs.

The various airlines have different methods of comput-
ing the cost per Ib per year of non-payload, which ranges
from $350 to $1000. Even at the lowest figure, it is plain
that the saving of a few pounds weight in so small an item
as dishes is well worth while. Depending on the size of
the plane and the type of service rendered, plastics dishes
make for a saving of five to 20 Ib in weight. Multiply this
by the cost of carrying a pound of non-payload, and you
have a decidedly worth-while economy.

A second selling point which went over strong with the
airlines was the superior impact strength of the plastics
materials. This not only decreased breakage loss in dollars
and cents, reducing at the same time the cost of replace-
ments, but on those relatively few occasions when the plas-
tics dishes do break, they do not shatter into fragments
which are difficult to collect, without cutting one's fingers,
as in the case of glass or china.

The appearance and feel of plastics materials were an-
other point in favor of the tableware. While it would seem
that their extensive color range would also be advantageous,
it has not in fact worked out that way. The airlines made
very careful tests of the effects of colors on passengers, es-
pecially during rough flying weather, and found that if a
person had a tendency to be airsick a good juicy green
would speed him on his way! The consensus has been
that, along with china white, neutral colors are best for this
application. Pearl white, ivory and buff are widely used.

PLASTICS

A final selling point was the cleanliness and easy wash-
ability of the plastics ware. Some airlines seemed to think
that china retained the food heat longer, but this does not
have a foundation in fact, and several of the lines which
clung longest to some chinaware items are also replacing
them now with plastics.

The first sale of Northern's dishes was made as far back
as 1936. The items ordered were two sizes of a square
serving plate, and these were followed by urea tumblers.
Pan American then fell in line with cups and saucers,
plates and cup holders (for hot drinks). TWA followed
with a special design of a complete set of dishes, including
plates, soup and salad howls, fruit cups and tumblers.
Gradually, practically all the companies have adopted a few
or many items of plastics. Now all DC-4's, for example,
have a complete plastics service, and when the DC-6's are
returned to service they also will mostly be so outfitted.

Along about 1944 melamine came into use to replace
urea. While this added about 10 per cent to the cost of the
dishes, the airlines had no objection because of melamine's
superior performance. It could be boiled, was higher in
impact strength, and stained much less readily than did urea.

Large Volume of Plastics Tableware Used

The volume of tableware used by the airlines is very
much larger than one might suppose offhand. It isn't only
a question of having a complete service on each plane. For
the caterers supply points all along the route and must be
furnished with several complete outfits so that they can re-
move the used dishes from an incoming plane and replace
them with clean sets for the next trip. And with each ship
added, there is need of further sets. Since the dishes now
in use are considered quite satisfactory, the further poten-
tials of the field would seem to be comparatively limited.
There is this to be said, however that there is plenty of
room for new designs. This factor is open to a great deal
of study, for plastics dishes used on the ground as well,
and there is no telling but that a striking creation might
lead to replacements of presently used sets.

An extremely interesting pooling arrangement for the
molds has been worked out by Northern. Although each
line owns its own molds, as in the case of other custom
molded jobs, Northern has worked out a procedure whereby
it can sell the products of these molds to any airline or,
indeed, to the general trade. For this it pays the mold own-
ers a nominal royalty, sometimes at a fixed rate, sometimes
at a variable rate depending on the size of the order. This
arrangement has worked out satisfactorily for both sides.
For its part, Northern has access to a variety of molds for
its customers, while the airlines have in several instances
had their initial mold costs repaid to them in the form of
royalties. In one case, the airline has received royalties
amounting to eight times the mold cost !

The excellent merchandising job Northern has done in
this field points the way to exploitation of plastics ware in
such relatively untouched fields as trailers, cruisers and
other small craft wherever a sturdy and lightweight dish
is desirable. END

Chain Store Merchandises
Plastics Products

(Continued from page 22)

Two diverse fields illustrate another situation that will
become familiar. Plastics have been so long accepted for
notions and for electrical appliances that there is no great
news in their use. About half the items handled by the
notions department utilize plastics in one way or another
and there is considerable activity in new products. In the
case of electrical appliances, molded phenolics and ureas

have been used so long that they are standard and no par-
ticular problem is given by them. It is noteworthy too that
in these two lines informative labeling is not considered by
the buyers to be particularly necessary or important. They
feel the consumers have become so accustomed to plastics
here that informative labeling would be superfluous.

Plastics are continually becoming more important in fur-
niture merchandising. Grant's do not keep a full furniture
line but do a big job in tables, smoker stands, hassocks, and
similar relatively small items. Unsupported vinyl film with
grain effects and vinyl-coated cloth is constantly replacing
alternate materials in chair seats and hassocks. Repeated
reductions in prices and improved serviceability underly
this development.

Lower Price Range for Plastics Hassocks

One new item about which I. W. Fonshill, furniture
buyer, is particularly pleased is a line of hassocks that
Grant's will be selling at a price range lower than any other
product of comparable quality. This hassock is beautifully
finished in vinyl coated cloth and is proved to have marked
superiority over other materials.

In general, the future of plastics is rosy, so far as Grant's
is concerned. As Harry A. Earth, Assistant to the Mer-
chandising Director of W. T. Grant, declared some time
ago in speaking to a plastics industry group, "I want to say
that retailers watch the dynamic growth of the plastics
industry with genuine pride in your achievements. We, as
do you, wish to see your markets increasingly broadened.
Now that you must embark more intensely on the dynamic
merchandising of plastics to sell your increasing supply of
materials and capacity, remember that American retailers
are on your side, we want to work with you, we want you
to consider us as members of your team." END

Plastics Parts for Hardware

(Continued from page 48)

tool may not only be regarded as a definite trend but also
as a stimulant toward the design of magazines on tools
which have not hitherto had them.

In tools such as the wrench and pliers, in which force
is exerted more or less at right angles to the operating
axis, the handles must necessarily be of one piece with the
rest of the tool, which is metal. Where the force to be
used is considerable, the wear and tear on the operator's
hands is of no small consequence. Contouring the handles
was the only resort until comparatively recently when the
plastics tool handle sleeve came into being. Molded, in most
cases, of cellulose acetate, cellulose acetate butyrate or poly-
styrene, the sleeves are force-fitted onto the metal handles of
these tools. They not only ease the attack on the hands, but
provide insulation against heat, cold and electrical con-
ductance. It might be pointed out that the tool handle
sleeve offers a field of application for the elastomers also.

Another category in which plastics are making them-
selves felt more and more is the utility packaging of tools.
This field is a natural for plastics, since they reduce the
over-all weight of the package and eliminate the rustability
of metal containers, entirely aside from adding character
to the package. Drill cases were among the first to enter
this application of plastics and, at that, comparatively re-
cently. They are being made now with both friction fit cap
or cover and with hinged closure. Files and grinding burrs
have recently become available in plastics cases.

Where previously plastics tool containers were generally
solid black or clear transparent, the trend toward bright
color is making itself evident here also. In fact, the latest
tendency is toward two-toned utility packaging for this
type of merchandise, as in the instance of the Rogers drill
stand, in which the base is of phenolic and the cover of
polystyrene. The two-toned design, in addition to improv-
ing the appearance of the package, has a practical advantage
for the mechanic in the differentiation between top and
bottom of the case. From the manufacturer's point of

"Easy-to-See" thermometer, indoor-outdoor. Chassis and
dial face are molded into one piece of polystyrene

view, the change from metal to plastics for utility packag-
ing of tools can. in many instances, offer not only the
values inherent in the material itself, but also the possi-
bility of reduction of manufacturing costs. The Precision
screw driver kit, with its transparent cellulose acetate cover
and aluminum base, is a noteworthy example. The Horton-
Stratfield Company, of Fairfield, Conn., intends to redesign
this unit, even now a new and going item, to give it a molded
plastics base because of the relatively higher cost of the
present machined aluminum base.

The field of utility packaging of tools has even more
room for plastics. Yearning for plastics cases, for in-
stance, to replace the present fabric-covered metal is the
whole group of precision measuring instruments. And wait-
ing for invasion by the elastomers are cases for pocket
rulers, small protractors and the like.

While the utility packaging of tools and tool accessories
in molded plastics and especially in lovely colors is a com-
paratively recent development, the packaging of small parts
in containers of transparent cellulose acetate and cellulose
nitrate rigid sheeting came into practice some time ago.
Patterson Brothers, however, have demonstrated that this
type of packaging can be turned into what amounts to a
retail merchandising principle. The store displays screws,
washers, nuts, bolts, cotter pins, cutters, die sets and a host
of other small parts in an array of tens of dozens of trans-
parent acetate vials that invite the customer to self-service.
Mr. George points out that, aside from the obvious fact
that this merchandise is thus given added protection against
dust and rust, it saves bin space, eliminates the cost of addi-
tional bin construction and prevents the inter jumbling of
parts from one bin to another.

The success of the plastics vial merchandising has im-
pelled Patterson to take a further step which proved re-
sultful in turn; it has developed a considerable business in
the unit sale of small parts packaged in acetate vials made
to their own specifications.

An additional potentiality not yet recognized by the hard-
ware jobber is the merchandising of small parts assortments
in the war-born, but now familiar, compartmented box of
molded cellulose acetate, ethyl cellulose and polystyrene.
That these boxes offer a merchandisable type of re-use
packaging is amply evidenced by their ready salability as
empty containers in hardware stores today.

The elastomers have not given a strong account of them-
selves in the hardware field as yet, except for hose. Still
from the angle of quantity, hose alone can be a considerable
consumer of material. The chief advantages of plastics hose
are reduction of weight, which becomes more important as
the length increases, and high durability. Yet, according
to Mr. (ieorge, the first application of plastics to hose was
inauspicious. Hose must be able to withstand extreme
cold and heat, a considerable range of pressures and the
effects of sunlight and weathering. The early plastics hose
met some but not all of these requirements, the most marked
defect being breakdown under low temperatures. All the
requirements are apparently being met by the newest de-
velopments in this product.

An example is .S/>/>/< ! .r, made by the Industrial Synthetics
Corp., Westfield, N. J. It is made of a modified polyvinyl
chloride in which a metallic compound is dispersed. One
of the chief advantages of this metallic impregnation is that
it reflects 64 per cent of ultra-violet light, lowering the
disintegration rate of the plasticizer and lengthening the
life of the hose by from two to four years.

Builder's hardware is another potentially open field for
plastics. Much has been done here already, with such
readily salable items as door knobs, door push and pull
plates, door stops, faucet handles, house numbers, latch re-
lease buttons, molding trim, nail heads, radiator control
knobs, tank floats, toilet paper rods, toilet seats, towel bars

and a number of others. But the possibilities are much
greater. Medicine cabinet and bathroom wall bracket
shelves are just a single example. The choice here would
seem to be between the frangibility of the glass shelf and the
abradability of the surface of the plastics one. But there
is a way of reducing the unsightliness of abrasion by mak-
ing the shelves of solid color plastics. The one serious ob-
jection to this suggestion offered by the hardware dealer
is to stocking a variety of colors of plastics shelving, but,
as far as bathroom shelves are concerned, this is readily
disposed of by confining solid color to cream and milk white.

Perhaps the greatest potentialities for plastics in hard-
ware lie in the heterogeneous field of the type of household
accessories normally carried by hardware stores. Already
available, among many other plastics items of this kind are
cabinet handles, can openers, curtain rod headers, drawer
pulls, faucet filters, funnels, knife holders, knife sharpeners,
soap dishes, soap dispensers, shower curtain hooks and
thermometers. The thermometer is an instance of a class
of product that has undergone widespread redesign by many
manufacturers for merchandising in plastics. The fact
that plastics will stand up well within normally experienced
extremes of air temperatures, for instance, has been utilized
by the Robert Bradley Company, Waltham, Mass., in the
single-piece polystyrene chassis and dial face of a new and
unusual type of outdoor thermometer which attaches di-
rectly to the window pane by application of adhesive to
rubber rim and thus eliminates the job of screwing the in-
strument to the window frame.

On the whole, the hardware dealer is receptive to plastics
components in hardware. In that, he is merely responding
to the receptiveness of his customers, of course. Untoward
earlier experiences with plastics in this field have not been
numerous, at any rate not sufficient to retard plastics prog-
ress here to any degree. Mr. George finds that, where plas-
tics have failed in hardware, invariably the fault lay not
with the material, but with its misapplication almost al-
ways functional misuse. There is far less of this today than
there was in the first year or so after the war. However,
since a hardware dealer, no matter what his size, can not
maintain a testing laboratory and, therefore, must rely on
the pre-production research and testing of reliable manu-
facturers, this firm tends to confine its buying to brand-
name merchandise. END

Tape for Tennis Courts

(Continued from page 54)

in \y 2 " width, .055" thick. It will be sold in three-yard
rolls, together with 4" copper nails to fasten it to the ground.
Galvanized iron nails, while cheaper, rust after the coating
is worn off, and aluminum nails would be corroded by the
chloride of lime used in drying tennis courts.

At present, the tape is punched out at 3" intervals along
both edges to receive the nails. Mr. Atkinson thinks that
6" intervals would be effective enough, and there is even a
possibility that the installation may be simplified by stapling
down the tape at the ends and supplementing it with scat-
tered nails where necessary.

The cost of installation, including materials, is estimated
at about $40 per court, which compares favorably with rub-
berized and impregnated cloth installations.

The origin of the polyethylene tape fits in with the pro-
verb that many a truth is said in jest. Robert A. Fisch,
president of Anchor Plastics, was playing tennis with some
friends and one of them, falling in with the popular notion
that everything is or can be made of plastics, said jokingly,
"How about a plastics tennis court tape?" Mr. Fisch said,
"Why not?" and his firm not long after came up with the
embodied answer. END

food fields, coil forms, and sheathing for wire and cable,
governor slide buttons, nuts and cores for polishing brushes,
and blind rivets. Several manufacturers are using nylon
for strain-relief plugs where the wire cord is attached to
the appliance.

Nylon zippers are being produced commercially and offer
promise because of their attractive colors, and "warmth"
where they touch the body. The material withstands the
action of dry cleaning solvents and the heat of ironing.

Emphasis was laid on planned approach to the use of the
material to avoid misapplication.

F. L. Yerzley, Mycalex Corp. of America, "Mycalex
410 Glass-Bonded Mica in Molded Form": Although
this material is a ceramic, consisting of finely divided mica
dispersed in a glass binder, it is molded in equipment and by
processes resembling those employed in the transfer molding
of phenolics. The material is characterized by freedom from
cold flow and carbonization, high dielectric strength, low
loss in high frequency electric fields, resistance to change
at temperatures up to at least 700 F, and dimensional and
electrical stability under a wide range of humidity and
temperature conditions. It may be molded with precision
approaching that common to metal parts and is adapted to
the inclusion of metal inserts capable of use as hermetic
seals. Features of design were discussed and illustrated by
reference to commercial molded parts.

Reid G. Fordyce, Monsanto Chemical Co., Plastics
Div., "Styrene Polymers and Copolymers for Industry" :
The advances made in providing the plastics industry with
polystyrene polymers and copolymers having greater versa-
tility and wider fields of application because of improved
properties, were discussed. The economic foundation on
which these developments rest was stressed, as well as the
threat to older materials in industries besides the molding
field. The salient differences between a polymer and a
copolymer, and the methods employed in these developments
were reviewed. Products were analyzed from the stand-
point of the outstanding property, or combination of pro-
perties, that the material has to offer the plastics engineer.
The actual and potential applications of these newer ma-
terials in a number of fields were indicated.

J. Searer, Durez Plastics & Chemicals, Inc., "Durez
Phenolic Resins in Synthetic and Natural Rubber":
These resins, specifically formulated for the purpose, act as
thermosetting (vulcanizing) plasticizers for both synthetic
and natural rubber, making all types of rubber processing
easier, while imparting material increases in hardness, abra-
sion resistance, stiffness, solvent and oil resistance, and age
resistance to the cured stocks. Excellent surface finishes
are also obtained.

Products utilizing resin-rubber blends now being manu-
factured include shoe soles, top lifts, gaskets, grommets,
molded rigid articles, and Ebonite-]\ke materials. Potential
products include artificial leathers, insulation, and GRS
automotive tire bead stock.

Rubber is being blended with phenolic molding com-
pounds, and improved flexibility and impact resistance have
been obtained experimentally. Durez phenolic resins are
presently being used to modify rubber-base adhesives, since
these resins increase adhesion, toughness, tack, and heat
resistance.

L. E. Cheyney, Battelle Memorial Institute, "Plas-
ticizers in the Plastics Industry" : Plasticizers are an
auxiliary group of materials used primarily for the purpose
of imparting either temporary or permanent plasticity to

the plastics mix, which may be varied widely by the proper
selection and use of plasticizer. Such properties include
hardness, flexibility, impact strength, resilience, electrical
characteristics, aging behavior, permeability, and others.
Recent developments in the field of plasticizers are responsi-
ble for new flame-resistant materials, applications of poly-
meric materials as plasticizers, and perfection of the paste
technique of fabricating vinyl plastics.

Dr. O. L. Pierson, Rohm & Haas Co., "Fabricating
of Heat-Resistant Plexiglas: Heat-resistant acrylic sheet
offers the well-known crystal clarity and good physical
properties of the regular grade, plus a markedly higher re-
sistance to heat, and is available in the same variety of
colors and patterns. Development of high speed aircraft
during the past three years has placed new emphasis on
resistance to heat developed by airflow friction. In addi-
tion, several new industrial applications requiring extra
heat resistance have come along. For example, Plexiglas II
has been used in street and industrial lighting, automobile
visors, demonstrator units such as domestic washing ma-
chines, vending machines, and aircraft enclosures and ac-
cessories.

To assist fabricators in its use, the Rohm & Haas Fabri-
cating Laboratory has developed techniques which differ
from those used with standard acrylics principally in form-
ing and cementing, which is best done with a Cement II
formulation developed by the company. This avoids exces-
sive soak times and will develop strengths nearly equal that
of the heat-resistant sheets if properly heat treated. Form-
ing requires ovens operating about 20 C. higher than for
comparable operations on standard acrylics. These higher
temperatures require more rapid handling during forming.
In some cases heated molds have proved helpful. Examples
of the fabricating techniques used in several fields were
discussed in detail.

Henry M. Richardson, DeBell & Richardson, Inc.:
"The Production Economics of Press Design." To be
competitive, the plastics molder must continually turn out
more and more pounds of salable molded parts per day
per press. To do this, he must be able to mold at lower
unit pressures to allow greater weight per heat from a given
press size ; must provide mold temperature and preheat
which will allow minimum flow and cure time; and utilize
pressing equipment which is fast and reliable so the press
operating time is as small as economically practical. The
other major factor is the amount of labor which must be
used to produce it. Controlled high speed press operation
and automatic cycle timing and control offer present op-
portunities for improvement.

The cost of material conversion was analyzed and charted
by its components, and the investment value of cycle time
savings indicated. For example, a 150-ton press might mold
a 15-oz. charge at 4,000 psi, but only half this quantity at
8.000 psi. A cure time of 40 sec. in each case and a change
and transfer time of 20 sec. indicates a material conversion
cost of from 5.6 to 7.7# per Ib. at 4,000 psi and 10.2 to
14.5< per Ib. at 8,000 psi. A reduction of cycle of 10 sec. is
worth annually, in the resulting savings during normal
three-shift operation, an amount equal to the amortization,
carrying charges, and taxes on an investment of approxi-
mately $10,000.

S. K. Moxness and J. Formo, Minneapolis Honeywell
Regulator Company, "Present Developments in Steam
Preheating": Another year of practical experience with
steam preheating has proved its practicability for general
transfer molding. Improvements in the method of metering
the moisture into the preheating atmosphere make it pos-
sible to maintain precise control over the moisture content
of the preheated preforms. This has made it possible to
control the shrinkage of parts over a wider range than is
possible with other means of preheating. It was emphasized

PLASTICS

MARCH 1948

that the amount of moisture in a properly functioning steam
preheating oven is very small, causing a relative humidity
of only about one to two percent. Tests have been limited
to general purpose and asbestos-filled phenolics in preforms
up to one inch thick.

Surface appearance of steam preheated parts compares
with parts molded with other methods of preheat. Strength
characteristics are often enhanced, while electrical charac-
teristics are very slightly reduced. The great influence of
very small amounts of moisture can be seen in the greatly
accelerated rates of softening.

Emil J. Marslek, Acme Scientific Company, "Design
and Finish Requirements on the Production of Plastic
Lenses": In the past it has been desirable to make lens
molds by hobbing methods because the hobbing produced
the highest finish and accuracy for this type of cavity. This
paper presented an alternative method of designing lens
molds which permits the use of optical methods in finishing
the lens surfaces, thus eliminating the need of hobbing by
use of inexpensive, inserts.. With these, it is possible to
utilize better grade materials, resulting in surfaces free of
inclusion and blemishes. These surfaces will also have a
true figure of revolution and optical in character. The use
of Newton's fringes for inspection of radius of curvature
and freedom of turned edge was mentioned. The reflec-
tivity and surface finish of the mold insert surfaces were
also discussed with some attempt to correlate this data with
actual surfaces produced on the plastics lens by the mold-
ing operation. No attempt was made to evaluate the con-
ditions which might be introduced by variation in plastics
materials or molding techniques.

happen, and when it does it is a source of vexation, to say
the least. Mr. T^risbie cites the case of an insulating wheel
rim on a locomotive molded of high acetyl acetate which
warped badly because of what he believes to be a substitution
of plasticizer. At other times, changes in molding powder
composition have led to inconsistent flow and to wide varia-
tions in the molded parts. Other drawbacks, in Mr. Frisbie's
opinion, are the low heat distortion points and the high
water absorption of the lower price thermoplastics, though
the latter failing can hardly be attributed to polystyrene.
Aside from that, he finds that the lightness of plastics,

which is so often a great advantage, would be a disad-
vantage in the construction sets produced by Gilbert. Here
he feels that the child likes the heft of metal, that he wants
to feel that he has "got hold of" something. As a result,
the company has thus far used only a phenolic mounting
base in its electrical set, for its insulation properties and its
appearance.

In general, Gilbert does not replace die-castings by
plastics where dimensional stability of the part is likely to
be affected, as by heat generated in the course of operation
of the device Gear boxes and motor housings, for example,
are still die-cast. Metal is also retained where weight is
essential. For the bases of the railroad cars metal plates
are used, attached to butyrate body with drive screws.
Gilbert not only makes laboratory and pilot run tests on all
its products, but also sends them out for consumer tests
before they are put on the market. As Mr. Frisbie says,
"The consumer does things to a product that the laboratory
doesn't think of," and if some of these things are "wrong"
that is what the manufacturer has to expect and forestall.
With a new item in the line, the company may distribute as
many as 50 pieces for this consumer field test, on which
reports are obtained once a week until a conclusive result is
obtained.

As an example, when Gilbert produced a J4" lightweight
electric drill for home use, it had them tried out in several
garages and shipyards as well as in many homes. While the
shipyard test was not really representative, since the drill
was not meant for heavy duty, it did yield a pointer for
improving the wear of the device. But the real test was in
the home, the market for which the drill was intended, and
the consumers were able to call attention to an obvious
weakness which did not show up in any of the laboratory
tests. For good reason there was nothing wrong with any
of the working parts of the drill. But the consumers, using
the drill in odd cellar workrooms, not as conveniently
supplied with electrical outlets as the laboratory, did find
out that the cord was not sufficiently long to reach their
distant sockets. A simple criticism, and one easily overcome
once the company realized it. That is why it is sold on
consumer testing. END

Promoting Marketer

(Continued from page 28)

marketer himself is responsible for providing the molder
with an operating mold. In any case, full ownership and
control of the mold is always held by the marketer, who
remains the proprietor of the product in question. Assembly
and packaging are often done by the molder for the account
of the marketer and he may even set up to drop ship orders
to particular outlets.

It is noteworthy -that although the marketer makes an
investment in molds and tools he does not acquire any
molding machinery and does not own any manufacturing
facilities. Although the marketer assumes the bulk of the
risk, the custom molder inevitably shares the risk to some
extent. Before production begins, he must invest the time
of his engineers in consultation, testing and mold design.
Of course, he hopes to recoup these costs in the price he
receives from the marketer for each piece. But if the item
is unsuccessful, even through no fault of his own, he stands
to lose the money he has put into preparatory engineering.

Normally, the molder supplies the material as part of
his piece price, but in other cases the promoting marketer
secures molding compounds from material manufacturers
or other sources and has it shipped to the molding plant
for his account. In such cases, with the marketer supply-
ing the mold and the material, the use of a molding machine

PLASTICS

MARCH 1948

is supplied by the molder at a flat hourly rate, including
operating labor, power and incidental services.

The promoting marketer's functions are of real impor-
tance in the industry since in certain fields a respectable
proportion of total production is under his control. This is
particularly true in toys, and playthings, in certain house-
ware items and even in some packaging applications. His
economic justification lies in the fact that many molders
are not merchandising minded and are reluctant to assume
the risks that are involved in proprietary molding. The pro-
moting marketer is therefore a risk-taker and a merchan-
diser and his success depends on the skill with which he
discharges his risks and performs these sales functions.

A rough analogy can be drawn between the function of
the promoting marketer and that of the textile converter
who buys so-called gray goods, comparable to plastics raw
materials, and has a commercial dyer, printer, or finisher
turn these into finished piece goods of particular types and
styles. The textile converter, like the promoting marketer,
does not own manufacturing facilities but plays the market
very closely, rushing in to meet new demands as they arise
and assuming the risks that are involved in gaging changing
public tastes and requirements. Certain markets for plastics
are as fast moving as the textile market, and the promoting
marketer must follow these markets closely and attempt to
learn what is wanted and to guess how these wants can best
be met, before his competitors see the same opportunities.
He backs his guesses with investments in molds and other
development costs and then carries out all of the marketing
functions from time product leaves molding shop.

This arrangement is a satisfactory one for many custom
molders who are not inclined to engage in a straight mer-
chandising activity. Many custom molding shops are run
by men with mechanical background who are neither skilled

nor particularly interested in merchandising as such. They
would rather spend their time running their shop as effi-
ciently as they know how and in meeting the numerous
problems that arise from it. They are willing to have some-
one take from their backs the burden of creating new prod-
ucts and the problems involved in getting those products
established in the market.

In some quarters a prejudice against promoting market-
ers has risen, overlooking the genuine contribution that these
firms have made in expanding the markets for plastics. Part
of this feeling arises from the practice sometimes indulged
in of shifting molds from one shop to another to achieve
advantages in price or material availability. The molder
often feels himself in an insecure position in this kind of
business, particularly since the promoting marketer may
have identical molds operating simultaneously in several
shops. In some cases, too, promoting marketers in times of
materials shortages, have appeared able to lay hands on ma-
terials not available directly to molders. The charge has
been made from time to time, often unfairly, that inde-
pendent marketers have been responsible for certain mis-
applications of plastics. Faced with a high demand for
finished products on the one hand and a restricted supply
of first grade material on the other, there has been at times
pressure to use incorrect materials with resultant effects on
quality and serviceability. But this tendency has not been
confined to promoting marketers by a long shot.

The increased availability of materials and the normal
competitive process has weeded out these alleged misappli-
cations and reports from merchandising circles indicate
that they are no longer a serious problem. In addition the
same development has induced a stabilization of the pro-
moting marketer-molder relationship so that complaints
on mold-jugging have greatly decreased. END

What's New

Plastics Injection Press Improved

Van Doin Iron Works Co.

2685 Erst 78th St., Cleveland, Ohio.

Major improvements in the Model H-200, 1 oz. capacity, In-
jection Press of this company include : A spreader which has
been added to the heating cylinder and reduces the time required
for the heating cycle by 50% ; internal hard chrome plating of
the heating cylinders to provide longer life, reduced resistance
to the flow of material and less corrosion when molding vinyl ;
relief set at 1500 psi to provide maximum clamping pressure
and independent adjustment of clamping and injection pressures;
and, a new needle valve in the hydraulic system to increase gauge
life. The price of the Model H-200 Press remains unchanged
from what it was (832)

Injection Cylinder for More Intricate Molds

Lester-Phoenix, Inc.
Cleveland, Ohio

Development of an injection
cylinder with independent tem-
perature control in its spreader
and a completely annular ma-
terial passage is an outgrowth
of original experiments with in-
ternal heating of the spreader.

The advantages claimed by
Lester-Phoenix are : increased
plasticizing rate for any given

f inventory of material ; more ef-

fective pressure transfer from
plunger tip to nozzle because of
a totally unrestricted material

package, a hot spreader, and warm feed section ; accurate tem-
perature control to within a few degrees of both the spreader
and the cylinder body in three zones ; improved purging prop-

erties for the cylinder ; and tapered, shrink fit of the spreader
to the cylinder body to permit easy disassembly for cleaning.
The vertical arrangement of the cylinder allows ready accessi-
bility of both the external and internal heaters for replacement.
The overall results of this new development, designed as a
general purpose cylinder for all thermoplastics, including Vinyl-
ite and Nylon, is that successful molding of larger pieces on
more intricate molds is now made possible. It can also be ex-
pected that, due to the excellent plasticizing ability of this de-
sign, less power is required to operate the pumps, less current is
required for the heaters, maintenance cost is reduced and pro-
duction is greatly increased (833)

Here, in a new, 28-page bulletin is a comprehensive descrip-
tion of a complete line of electric hygrometer equipment suitable
for exacting industrial and laboratory applications. The booklet,
A^o. 2140, is generously illustrated. Among other devices it lists
a tiny sensing element that responds within a fraction of a sec-
ond to increases or decreases of relative humidity as small as
0.1%. This element measures with an accuracy of within plus-
minus \^2% relative humidity, when used with suitable equip-
ment. It is relatively independent of such limiting factors as
restricted circulation of atmosphere around the sensing element,
extremely small mounting spaces for sensing elements, remote
installation of indicating or other equipment, and subjection of
the sensing element to vacuum or pressure (840)

* DEVALUATION AND PLASTICS

<I Devaluation of the French franc increases the
cost of American plastics materials to French
manufacturers. Substantial amounts of molding
powders are now being shipped to France, which
is a good market having over 600 molders.

[ Devaluation, on the other hand, lowers the
prices of French goods to Americans. This will
stimulate purchases- by Americans of French
goods, and will result in placing more dollars in
the hands of the French, with which they can
purchase more plastics. International economists
believe that the devaluation was a necessary step.
The cheap price of the dollar, pegged at 119
francs, stifled trade as much as would an arti-
ficially high price. At 250 francs, the price is
more realistic, nearer the black market rate. Only
the next few months will clearly show if the new
base is right. If it is not, the French may find it
cheaper to buy their raw materials from Germany,
England, Belgium or Switzerland.

* INCREASED CONSUMPTION

<jj New life is being instilled in the use of cellulose
acetate, with results indicating a gradual return to
1946 levels of consumption. The biggest drop
was in molding powders. However, now the con-
sumption is averaging 5,000,000 Ib per month for
both cellulose acetate and butyrate. Much of this
higher level is due to the intense promotion carried
on by the cellulosic producers, to interest molders
and consumers in the superior qualities of high
acetyl cellulose acetate in hard flows. Little seems
to be known of the advantages of these hard flows,
but indications are that new possibilities are being
projected. It is known that better dimensional
stability can be imparted by the utilization of an
H 6 flow in high acetyl. END

Plastics in Perspective

enough plastics materials in the country to supply the
bodies required by any one large auto manufacturer.

AT A GAB-FEST of Broadwayites the other day, a
moderately unsuccessful producer in a fit of self-
pity ventured the remark that he was his own worst
enemy. "Not," said the sharp-witted Franklin P. Adams,
"while I am here." Like show business, the plastics in-
dustry does not lack for keen critics ; and it's a salutary
thing. Writers and producers of bad or mediocre plays
always attribute their troubles to the critics, who, ac-
cording to them, delight in "panning" plays. Nothing
could be further from the truth, which is that critics go
out of their way in ther search for merit, and often

PLASTICS

MARCH 1948

overpraise a fair play because there are so few good
ones.

However, it is true that there are a great many people
who, through ignorance, make unwarranted criticisms
of plastics as a whole. But they are really less danger-
ous to the industry than those manufacturers who use
plastics in their products without due regard for their
limitations as well as their virtues, who use plastics for
the sake of plastics. One is reminded of the observation
that the reason people applaud the antics of trained dogs
and women political speakers is not that they do it well
but that they do it at all. Some people will use plastics
because they can be made to do in a given application.
That is not enough. Plastics should be specified when
they can do a better job than any other material. That is
the moral of the article published elsewhere in these
pages on the employment of plastics in the products of
the A. C. Gilbert Company. We intend to publish many
more articles of this kind, for a sound industry cannot
be based on amateur enthusiasm but only on sound en-
gineering.

SPI Low-Pressure Sessions

(Continued from page 30)

Dr. F. L. Minnear, Shellmar Products Corp., "Evalu-
ation of Thermoset Laminated Sheet Products": Ma-
jor advantage of continuous laminating with polyester resins
over high pressure laminates is that it may be used for the
rapid production of thin sheets from Me" down to 0.005",

which can be made very pliable with little or no difference
in the other general properties. This opens up entirely new
fields for thermosetting laminates, such as wall covering,
especially for bathrooms, and kitchen sink counter covering.
"The continuous process of making contact-pressure lami-
nates has enough advantage for it to carve out its own field.
That there will be some instances when it will overlap into
some applications of phenolic laminates is likely, just as it
will compete with wood and metal and linoleum for some
uses. That it will displace any of these materials, as has
been claimed, unfortunately, by some promoters in this field,
is just plain silly talk. The advantages of phenolic lami-
nates are numerous, and it is my opinion that the future
will see these two processes complementing each other
rather than competing."

The banquet speaker was Ralph W. Carney, sales man-
ager, Coleman Co., Wicheta, Kansas, who outlined the
requirements for a good sales presentation.

The addresses seemed to be preponderantly directed to
continuous laminators, despite the fact that the vast majority
of the companies represented were not in that field. Possibly
this was justified by the fact that the small number of com-
panies engaged in continuous laminating account for by far
the greatest tonnage of resins and fillers. However, at a
closed forum following the general meeting, in which Clare
Bacon, Owens-Corning Fiberglas Corp., also participated,
and of which B. Darling, the Riegel Paper Corp., was
moderator, the questions answered both by the panel and
from the floor concerned phases of low-pressure reinforced
plastics molding other than continuous laminating. For
many members present, a single question answered at this
forum made their attendance at the meeting more than
worth while. END

Sun/amp Has Unique Application in Plastics

Plastics research has uncovered a new application for the
sunlamp and its ultraviolet light, the photopolymerization of un-
saturated organic compounds as vinyl chloride and methyl aery-
late. Ralph F. Hayes, Springfield, Mass., found that when one
part of 2, 7-dichloro diphenylene sulfone (aromatic sulfone) was
mixed with 100 parts of methyl aery late and subjected to an
ultraviolet light from a sunlamp at 74 C, the methyl acrylate
polymerized to a solid mass in 35 min.

Hayes discovered that the sunlamp 2, 7-dichloro diphenylene
sulfone catalyst combination could be applied to vinyl esters like
vinyl acetate, vinyl formate and vinyl butyrate ; vinyl halides such
as vinyl chloride and vinyl bromide ; vinyl ethers ; vinyl ketones ;
vinyl aromatic derivatives such as styrcne, divinyl benzene, vinyl
diphenyl ; substituted styrenes including mono and poly chloro
styrenes, and mono and poly alkyl styrenes.

Acrylic derivatives, which can also be used, include acrylic acid
and alpha alkyl substituted acrylic acids and their esters, and
nitriles such as methyl, ethyl and propyl acrylates, methyl and
ethyl methacrylate, methyl ethacrylate, acrylonitrile and metha-
crylonitrile.

In a test with 100 parts of styrene, the styrene polymerized
after IS hr to a slightly yellow mass, which on analysis proved
to be 97 per cent polymerized. In another test, vinyl chloride
polymerized to a solid mass in 4 hr.

The 2, 7-dichloro diphenylene sulfone catalyst accelerates poly-
merization. In a test with a mixture of 85 parts of vinyl chloride
and 15 parts of diethyl maleate, with and without the catalyst, the
catalyst mixture polymerized in 12 hr, while the mixture without
the catalyst remained liquid after 24 hr.

The amount of the catalyst may be varied from .1 and about
5 percent of the weight of the monomer or monomer mixture.
The percentage of catalyst can be determined by the molecular
weight desired. For instance, an increased catalyst concentration
causes a decrease in the molecular weight of the polymerized
product.

The temperature of the polymerization reaction also may be
varied, between 25 C and 150C.

New Processing Techniques

Phenol shortages have prompted the development of several
interesting processing techniques. Coal tar residue has served as
a base in one method to provide crude resorcinol with up to 25
per cent phenol. In another method, up to 25 per cent phenol has
been recovered from mixtures containing phenol and resorcinol.
In this process, developed by Harold W. Mohrman, Springfield,
Mass., the cumbersome coal-tar resorcinol purification methods,
which result in substantial losses of phenol, have been overcome
with a formaldehyde treatment. Phenol is removed by distilla-
tion and subsequently purified by further distillation or solvent
extraction.

During one test, Mohrman placed 962 parts of crude resorcinol
containing about 20 per cent phenol in a glass flask, added 340
parts of 37 per cent formalin and 300 parts of water. The mixture
was heated at 40 to 50C until the resorcinol was completely
dissolved. The reaction was then heated for 15 min to reflux at
atmospheric pressure. Phenol and water were then removed by
distillation under reduced pressure at 120 C. When all the phenol
and water were removed, the reaction mixture was poured from
the flask and cooled. A hard, brittle, two-stage resorcinol, con-
taining no free phenol, was obtained, and 180 parts of phenol
were recovered from the distillate by solvent extraction.

The amount of formaldehyde used can be varied up to about .8
mol per mol of resorcinol. The upper limit depends on the
amount of formaldehyde which will combine with resorcinol to

PLASTICS

yield a liquid resin, when hot, from which phenol can be distilled.
A solid form of formaldehyde, such as paraformaldehyde, can be
used in place of the aqueous formalin.

The temperature at which the phenol and water are removed
from the reaction mixture controls the melting point of the resin,
a low temperature providing a low melting point.

Mixtures of highly-reactive substituted phenol and ' relatively
large quantities of phenol can be used in place of the resorcinol-
phenol mixtures ; 3, 5 xylenol-phenol, catechol-phenol and pyro-
gallolphenol mixtures.

No catalyst is required in the Mohrman process, and accord-
ingly the resins have a high electrical resistance.

Plastics Scrap in Textile Field

Plastics scrap processing is particularly active in the textile
fields. Pure acetate rayon scrap, for instance, is widely sought,
since it can be reused by dissolving and forming into filaments as
in the original production of acetate rayon. However, it has been
difficult to reuse acetate rayons which have other fibers inter-
woven because of the chemical variables in the fibers.

Orlan M. Arnold, Troy, N. Y., has solved the problem with a
fibrous-forming process. In the Arnold method, cloth or textile
scrap with over 10 per cent cellulose acetate fiber, and the balance
an insoluble fiber such as viscose rayon, is thoroughly cleaned and
conditioned to a moisture content of about 2 to 4 per cent. Con-
tents of the fibrous materials are then estimated for the correct
proportion desired in the material (acetate rayon 50 per cent,
viscose rayon 40 per cent, cotton fiber 10 per cent), and scrap
added if necessary to secure the proportion. The scrap is put
through a cutter which cuts the cloth into pieces of about 60 mm
average diameter. The cut material is then put through a shred-
der or a carding machine to open out the threads in any bits of
remaining fabric. The fibers are picked up in an air stream and
carried through blowers into a chamber where they are thor-
oughly intermixed, and any orientation destroyed. Plasticizers,
pigments or dyes are sprayed into the chamber to become inter-
mingled with the fibers. The composition which settles at the
bottom of the chamber may be treated for sheets, etc.

Instead of acetate, other cellulose esters, nitrates, etc., or nylon
can be used with suitable solvents, and instead of or in addition to
viscose, any other fibers insoluble in the solvent used, such as
cotton, silk, wool, or glass.

Wafer as Emu/sifier

Water can be used to emulsify polyvinyl acetal and butyral
resins, according to a development by Alexander J. Geiges, East
Orange, N. J. The plasticized resin emulsion can be used to im-
prove the surface structure of paper or cloth. In the manufacture
of paper, the resin is added to the paper fiber slurry suspended in
water as the slurry is being masticated in the beater tanks. After
the paper is relieved of the water, it will contain fibers coated
with plasticized acetal resin.

One solution, prepared by Geiges, contained 750 parts of poly-
vinyl butyral resin, 675 parts of pale brown castor oil having an
acid number of 20 and a viscosity of about 40 poises, and 75 parts
of castor oil fatty acids having an acid number of 170. The resin
was milled in a heated (250 F) dough-type mixer, solvent plas-
ticizer being added slowly. Heat was turned off when a homog-
enous mass of plasticizer and resin appeared, and cold water run
through a jacket on the mill until the temperature was reduced to
about 200 F. A solution of 10 per cent aqueous caustic alkali
such as soda or potash was then introduced, as milling continued,
to reduce the acid number to about half of its original figure.
When a temperature of about 120 F was reached, a 10 per cent
solution of ammonium hydroxide was introduced. This reduced
the acid number to approximately zero.

Plasticizers for this process should have acid numbers of 20 to
40. Solvent-plasticizers in this category are castor oil (c.p.) ;
ester type derivatives of vegetable oil fatty acids, such as the
butyl ester of the fatty acids present in naturally occuring castor
oil ; oxidized and polymerized vegetable oils, commonly known as
blown vegetable oils ; and the chemical plasticizers, dibutyl phtha-
late, dioctyl-phthalate, tricresyl phosphate, triphenyl phosphate,
dibutyl sebacate, etc.

The success of the process appears to be due to the use of plas-
ticizers which are either actively polar themselves, or compatible
with polar materials that also have at least partial solvent effects
on the resins. Incidentally, the plasticizer should be relatively
non-volatile at room temperature. END

Metal Turning Made Easy
with New Simplified Tool!

A new tool called "Tru-Turn"
makes possible the conversion
of drill presses, woodturning
lathes, or grinder stands into
tools that will turn and cut-off
steel, bronze, copper and alu-
minum. The "Tru-Turn" tool
shown above is mounted on a
Buffalo Drill Press, Spindle
Size.

The "Trw-Turn" tool is easy to
operate and cuts and turns bar
stock of steel,bronze,copperand
aluminum measuring V4", H"
and Vi". Its built-in microm-
eter permits adjustments that
give tool-room accuracy to
1/1000 of afh inch.
Small tool shops as well as all
types of repair shops and ga-
rages find the "Tru-Turn" ideal
for cutting long pieces of bar
stock into desired lengths. Also,
home craftsmen are able to
produce accurate, highly fin-
ished precision-machined
parts from metal even without
previous training.
Accurate, precision work is
also easier to do when tension
is relieved by chewing gum.
The act of chewing seems to
make the work go easier, faster'
'* thus helping on-the-job effi-
ciency. For these reasons
Wrigley's Spearmint Chewing
Gum is being made available
more and more by plant own-
ers everywhere.

SHIPMENT and consumption of plastics and synthetic resins
in the United States during the month of December moved
sharply upward, as shown in the statistics released by the Bureau
of the Census.

Gains over the figures for November appear in individual
classifications within several groups. These groups are, respec-
tively, cellulose acetate and mixed ester plastics ; nitrocellulose ;
phenolic and other tar acid resins ; urea and melamine resins ;
polystyrene; vinyl resins, wherein all classifications showed a
decided gain. In the miscellaneous resins group, molding ma-
terials showed a decrease, while all other miscellaneous in-
creased.

Shipments and Consumption

The statistics represent the shipments and consumption of
plastics and synthetic resins as reported by 83 manufacturing
companies or company departments in the United States. Quan-
tities, which are manufactured by the reporting companies or
company divisions and shipped to both domestic and foreign
users, are included in the shipment data. Consumption data are
limited to the quantities of plastics and resins which are manu-
factured and used by the 83 companies or company divisions
covered by this report. Statistics are available beginning June

NEW GEON paste resins mean
simplified molding, casting, coating/ and dipping

THE picture you are looking at
is not an exaggeration.
"Geon Paste Resins" means new
things in the vinyl plastics field. A new
resin-plasticizer paste can now be pre-
pared by a simple stirring operation.
In many applications it will eliminate
the need for heavy and expensive milling
equipment, grinding, dangerous vola-
tilesolvents, and high pressuremolding,

calendering or extruding operations.
The new Geon Paste Resin can be
mixed as simply as you see it done
here. Color any color, brilliant or
pastel can be added. The mixture
can be molded, cast, extruded used
for coating and dipping for paper and
textiles. Thin, medium, or heavy films
can be developed supported or un-
supported. These can be beautifully

embossed or printed as simply as those
produced by any other process. And
in casting, there is virtually no shrink-
age in the mold even though no pres-
sure is used. In dipping and coating,
usually only one operation is called for.
Yet Geon Paste Resin results in a tough,
homogeneous, and flexible body.

From packaging to luggage, uphol-
stering to shoe soles, toys to large
electrical cables, Geon Paste Resin
will make its contribution. We make
no finished products from Geon or
from any of our other raw materials.
However, we are glad to work on spe-
cial problems or applications. And we
believe you will want the bulletin just
published on Geon Paste Resin. To
receive it, please write to Department

THERMOCREASER

You get more creases in less time, witK the Taber Thermo-
creaser. That's because of the Thermocreaser's "quick crease"
action, from its accurately heated, thermostatically controlled
creasing blade that presses the material into a metal forming die
or a resilient rubber pad to produce a perfect 90 angle.

Through its special two-blade feature, the Thermocreaser is
equipped to handle a variety of creasing jobs. It is particularly
well adapted to production of transparent set-up type boxes, from
die-cut blanks, either plain or beaded.

PLASTICS

A MOLDER WHO is producing
** polystyrene poker chips received
some complaints from eagle-eyed
buyers that the edges were not perfect.
They were of course referring to the
remainder of* the gate. It was only a
pin-head irregularity which most peo-
ple would either overlook or forgive,
considering the low price of the prod-
uct. Yet, to offset possible complaints
from the more meticulous buyers, the
molder hit on a clever device. In his
informative label he stated that "the
mark on the rim of each chip is a
degate mark characteristic of injection
molding. . . ."

We think it clever, not merely be-
cause it faced facts constructively, but
because it has a kind of authoritative
technical air which impresses the lay-
man even if he doesn't know exactly
what it means. If the statement had
stopped at the point we have quoted,
the molder will have accomplished his
purpose. But the label goes on to
say: ". . . . and serves as a guarantee
that these chips are injection molded of
genuine -polystyrene." That is obvious-
ly misleading since the gate mark
would be there if any other thermo-
plastic material were used, and it only
confuses the layman. The information
that the chips were made of poly-
styrene and the use directions given
later on, were good, but they should
not have been tied in to the opening
statement. ^

Reports of much more extensive use
of various plastics in the lamp field
are received almost daily. For a num-
ber of years cellulose acetate sheet,
made specifically for this market, has
found wide acceptance. More recent
developments are the apolication of
molded polystyrene lamp shades. It
is not likely though that molded
polystyrene will replace sheet material
because of the great freedom of design

permitted in sheet fabrication.
* * *

There appears to be a distinct trend
toward the use of acrylic sheet ma-
terial in large advertising signs. Units
as large as 7'x5' are now considered
almost commonplace by sign manu-
facturers. * * *

Ethylcellulose in injection molded
handles appears to be opening up the
market for plastics. Attempts to apply

the materials in this field began more
than ten years ago but by various
reasons led to the dropping of this
development by some of the most im-
portant people in the field. Their in-
terest is reviving due to the properties
available in ethylcellulose.

* * *

Potential use of plastics in auto-
mobile seat covers is broadened by the
use of relatively low cost twisted paper
fibers. Extruded filaments of Styron
have moved into the high cost brackets
of this field. But now the low cost end,
dominated by twisted paper, is opened
by the application of Vinyl coatings
to the paper arms, yielding greater
serviceability, water and sun light
resistance and are attractive, richer
colors.

"T"O CLARIFY the complex set-up
' which has developed in the vinyl
film industry, we are publishing in
this issue a chart which shows the rela-
tionship of all factors from the base
ri'sin manufacturers to the retail out-
lets of finished goods. The term "con-
verter" appears in this chart, based on
the analogous use of the word in the
textile industry. In this connection, it
is interesting to note that the Textile
Distributors Institute has begun an
advertising campaign in the consumer
and trade press to explain the tradi-
tional function of the converters to
weavers, cutters, retailers and con-
sumers. The report that this move was
intended to counteract the trend of
rayon weaving mills to build up verti-
cal organizations which would enter
the finished goods field, was denied
by the head of the converters' group.
But there is a clear implication for
converters of vinyl film here that they
had better operate on a sound economic
basis if they are to retain their

position.

* * *

A PROPOS of a forthcoming revo-
**lution in the doughnut field which
would have that traditional "delicacy"
and leave it with half a hole, a com-
mentator in the New York Times
ironically remarked that ''there are,
fortunately, a number of things which
do not lend themselves to improve-
ment." One of these, he said, is the
-egg, "which is about as efficient a
package as it ever will be." Designers

of plastics packages, take notice !

IN ANNOUNCING a series of
meetings, a New England farm
improvement group announced that
"there will be no dry speeches or lec-
tures, only practical experiences re-
lated by working farmers." Attention,

"T"HE FEDERAL Trade Commis-
sion has dropped five cases in
which companies making plastics ma-
terials or products using trade names
with "glas" or "glass" as prolix or
suffix, were accused of misrepresenta-
tion. The point, if you can make it out.
is that customers might be misled into
thinking they were getting a glassy,
glass-like or downright glass product.
The FTC's sensible decision to forget
about it all was based on the fact that,
since these cases were put on the
docket, a U.S. Circuit Court of Ap-
peals has set aside an order issued In
the Commission to S. Buchsbaum \
Co. to stop using its trade name.

AS PART OF A L()N(i KANC.K
** program to promote the use of
the right plastics for a given applica-
tion, one of the plastics materials com-
panies has been running a scries of
ads to demonstrate the point. Laudable
as the effort has been and there is
room for much of the same sort of
educational effort - - the company
slipped up a bit when it implied, in
one ad, that only thermosetting mate-
rials can properly be used for buttons.
While there is no doubt that where
A button necessarily will come in con-
tact with a hot iron, a thermosetiiim
material is indicated, there are many
uses in which the crucial point is not
resistance to temperature so much as
resistance to dry cleaning solvents.
Some of the thermoplastics are more
affected in this respect also, especially
since the introduction of the hyclro-
i arlxm perchlorethylene as a solvent,
vet the National Institute of Cleaning
& Dyeing has reported that cellulose

* CONDITIONS OF SALES
CONTRACT FOR PLASTIC
MATERIALS

C, Few molders have ever read the
fine print on the back side of a mate-
rial suppliers order acknowledgement.
More molders should. What they
would learn is that the materials they
buy have little or no warranty. This
seems unreasonable on the surface but
the reasons for it are sound. Few ma-
terials can be expected to comply
universally with published data sheets
in view of the many varied conditions
under which the materials are used.
Recognizing this, some ' companies
warrant that their offerings will meet
certain specifications which they list.
These relate to the results of their
own tests under their own conditions.
In spite of all that a high powered
salesman may say, many a company
will not stand back of his statement.

4L "Upon request Seller will furnish
such technical advice as it has avail-
able in reference to the use of its
product by Buyer. It is expressly
understood, however, that such techni-
cal advice is given gratis and accepted
at Buyer's risk, and there shall be no
obligation or liability upon Seller for
advice given or results obtained."

C_ Once the material has been used,
it is too late and most companies
bluntly tell their customers that but
in fine print. What constitutes a rea-
sonable sample to evaluate a shipment
has resulted in many an, unfortunate
misunderstanding. Some companies
say "Buyer will make an examination
and test of each shipment within a
resonable time after its arrival at
destination. Buyer will then give
prompt written notice to Seller of any
defects or inferior quality claimed, or
of any other cause or condition which
is the basis of a claim, and will afford
Seller's representative the opportunity,
for a reasonable time, to examine and
test the material."

C. Generally materials are sold on a
use-constitutes-acceptance basis. This
means that when the material is used
it is considered acceptable and is no

longer subject to claims or recourse.
The thinking behind these claims
above is to avoid interminable law
suits.

CL Material companies might sell their
finest product to one molder whose
design and molding conditions brought
out the best properties of the plastics,
while another might design and mold
poorly to producing an inferior prod-
uct with the same material. The bad
product is no fault of the material
supplier. Even though their engineers
might have recommended and even
helped in the engineering, the respon-
sibility must rest entirely upon the
molder or his customer.

if SPI EXPORT COMMITTEE

C. SPI should soon be able to render
greater service to its members through
the formation of an export committee
which may form the base upon which
SPI can assemble data concerning ex-
port opportunities. Reports of various
foreign markets which have appeared
in this magazine have been stimulat-
ing enough to warrant a systematic
job being done. If America is to
earn and keep a strong posiii m
in world markets, the Sl'I should use
all posible means to encourage the
Plastics Industry to seek foreign out-
lets. It should show the potential of
such business and relate the business
activity cycles to domestic and foreign
sales by plastics products. The lag in
foreign business varies often from six
months to two years which may help
in leveling out the seasonal or cyclical
fluctuations of business.

* THE PINCH ON EXPORTERS

C. The March 1 requirements for ex-
port licenses has effectively placed
those who are strong in the export field
in a preferred position. Domestic ex-
port firms with strong agency connec-
tions can efficiently file and expedite
applications. They know their operat-
ing ratios so they can offer their own
foreign agents or own foreign offices
sufficient margins on which to operate.

C, Recently a fine but new export
company spent 1945 and 1946 estab-
lishing sources of supply and foreign
agencies. It received a 5% commission
but on its limited volume this commis-
sion was needed to operate the busi-
ness. It had no margin to offer foreign
importers. In 1947 this made little
difference because a fabulous incre-
ment could be added to the domestic
price due to the unsatisfied demand.
1948 is different. Foreign plastic users
are familiar with American prices and
will buy at only those prices. They

refuse to pay more. So they buy
through channels that offer standard
grades at standard prices. The foreign
agent realizes he must buy from the
American factory directly earning the
5% commission himself. This, of
course, eliminates his American mid-
dle man.

C. To keep their businesses alive some
domestic exporters are offering to split
their commission 2 c /c in America and
y/c abroad. Some are buying surplus
stocks at low prices and making their
markup on those products. As a tem-
porary expedient, this is satisfactory.
For the long pull it will not work. In
the first place, 2 r /c or Z% is too little
upon which to operate. Secondly, to
offer consistent quality from month to
month they must buy from a prime
producer. Their only alternatives,
therefore, are to demand larger com-
mission rates from their suppliers, or
build up a volume so that they can
exist on a 2% or 3% margin.

C. American plastics manufacturers
are becoming aware of these facts and
are setting out to establish their own
agents in each country. Of course, the
well-established exporters offer a serv-
ice that is worth more than the regular
commission rate. They have estab-
lished their place and should continue
to thrive. They also have an edge be-
cause the export license will be granted
probably to the lowest bidder and by
Shading a commission they can become
the lower bidder where "it is worth-
while."

* BUSINESS ACTIVITY

C. After trending downward for a
month and being jarred to caution by
the commodities drop, business activity
once more appears somewhat stronger.
Perhaps this is only temporary, relat-
ing largely to the heavy carloadings
and the change from the free/ing
weather which gripped the entire F,ast.

C. Rightly or wrongly many a busi-
ness executive still feels that the com-
modities drop rang the warning ball
for a business recession. Today's rela-
tively unimportant signs may stand
out tomorrow as the sign posts to
which "Monday morning quarterbacks^
can point and say "It was obvious."

C. This column still is bearish. Many
plant expansion projects have been
curtailed or deferred. Purchasing is
cautious. The metalworking industry
in New York reports broad retrench-
ment. Rubber tire manufacturers have
cut hours. Rubber futures are quoted
below 18^ per Ib. When that happens
the demand for synthetic rubber is

ON THE BALL

OR BEHIND IT?

With industry clamoring for better products, businessmen
are leaving no material unexplored which suggests a better
answer to their current requirements.

Our type of laminated plastics Synthane may be your
answer to better products because it has not one, but many
valuable properties in combination.

For example, you can depend on
Synthane for tensile, compressive,
flexural and Impact strength.
Compares favorably with metals
on a strength-far- weight basis.

Light weight is one of Synthane' s
most useful properties. Weighs
about half as much as aluminum,
has ample strength for all elec-
trical and most mechanical ap-
plications.

As an electrical insulator, Syn-
thane is one of the best high
dielectric strength, low power fac-
tor, low dielectric constant. May
be quickly and easily machined.

Synthane is the set plastic, sta-
ble over wide variations in tem-
perature.

Perhaps one of these or other Synthane qualities suggest its
use in your product. If so, let us help you before you design

Plastics where plastics belong

Because of a unique combination of chemical, electrical,
and mechanical qualities, Synthane laminated plastics can
be applied to an endless number of practical purposes.
Moisture and corrosion resistant, light-weight and struc-
turally strong, Synthane has many collective advantages
not readily found in any other material. One of the best
electrical insulators known, Synthane is hard, dense, dur-
able . . . quickly and easily machined.

Among the interesting occupations of our type of tech-
nical plastics are the redraw bobbin and chuck (below)
used in winding fine denier nylon for women's hosiery.

Fine nylon filaments can be wound without pulling and
sticking because of the smoothness of the bobbin. Light
weight of bobbin and chuck allows the spindle to be started
and stopped faster and with less effort. Greater crushing
strength of tube permits larger amounts of nylon to be
wound. This is an appropriate job for Synthane, an inter-
esting example of using plastics where plastics belong.

If any of Synthane's many properties suggest a use
for it in your plant, let us help you before you design.

* NEWS FROM THE STORK

^I_ The National Industrial Confer-
ence Board has completed an analysis
of the effects of population trends in
the United States. "A growth which
surpassed all expectations." Only a
little over a year ago, the Census Bu-
reau estimated that the national popu-
lation, as of today, would be around
142,000,000. Instead, the current popu-
lation is more than 144,000,000.

C, It had been the fashion for statis-
ticians to forecast a peak of no more
than 165,000,000 for the United
States, such peak to be reached a little
more than twenty years hence. The
N.I.C.B. analysis declares that the
present surge of births now indicate a
peak 10,000,000 to 25,000,000 higher,
with the upward trend continuing until
some time after the year 2000. Adds
the report :

C. "The significance of a large popu-
lation to businessmen and government
can hardly be overestimated. Manu-
facturers of children's clothing and

toys, obstetricians, and hospitals ob-
viously are immediately affected. Some
of the deferred effects of the boom in
birth rates will be felt by an increase
in the number of students entering
schools during the coming years. A
20% increase in births in 1946 por-
tends, roughly, a 20% increase in
labor- force entrants in the mid-1960s.
The number of marriages should in-
crease substantially twenty to twenty-
five years hence. . . . This will cause a
corresponding increase in demand for
housing.

* WHO'S NEXT?

C. Jst when America was beginning
at last to eye foreign fields, Stalin
closed the door to another market of
7,000,000 people to cool the ardor and
romance of foreign business a bit.
Competitive terms of "payment upon
delivery of goods" are pushed into the
background and the necessity for cash
in the hand before delivery is extended
indefinitely. Who wants to risk pay-
ments from Finland, Italy, Greece or
any one of the other spots being
greedily eyed by the newest taker-
overer ?

C. Selling in Europe on sight draft
terms was beginning to be quite satis-

factory. Payments were reasonably
prompt. On the other hand, in South
America, as attractive as is that mar-
ket, many concerns are weighing the
reasonableness of waiting 90 to 180
days for payments. Economic and
political conditions can change too
quickly and radically in that time and
the best calculated risk may turn pretty

* NEW NYLON FABRIC

shrinking, curling and flammability, a

ciates. This material is crimped and

What's Ahead In Industry Use

It's too early to predict final outcomes, as they may be represented in complete
products, but the optical industry is speeding up activities to find out what plastics
can do to further improve its offerings in various ways. For one thing, there is the
impending use of polystyrene as a prism in a redesigned instrument for a spe.cialty pur-
pose. If not the first, this is at least one of the earliest instances of a transparent
plastics replacing traditional glass in a precision optical component.

* * *

Inevitable, of course, but here it is. Heat-resistant thermoplastics are making
their debut in table radio cabinets. There have been a number of battery-powered port-
ables housed in injection-molded thermoplastics but the need for higher heat-resistant
properties has blocked progress in higher wattage sets. As a matter of fact, it was the
need for materials to meet this specific service that offered the principal incentives
for the development of those plastics specified for the several jobs now under way.

* * *

Rigid transparent packaging continues to make well-deserved inroads into consumer
goods fields. One of the latest uses is in packaging toy construction kits which, inci-
dentally, are composed of a colorful group of molded polystyrene and acetate butyrate
units. No need to elaborate on the merchandising advantages involved. Other instances
of rigid packaging with cellulose acetate sheeting have had to depend upon the ingenuity
of the package designer to find ways to make the plastics material meet its competitive
opportunities. There are advantages to be pushed and difficulties to be overcome.

* * *

Step by step, change makes itself felt in even the longest established end uses.
There's the field of drawing instruments where cellulose nitrate has its long record of
honorable service. Well, it's getting a shot in the arm now with the incoming of rigid
vinyl and molded polystyrene products.

* * *

An interesting intra-industry competitive situation has developed in the toilet
seat field. Nothing new about molded seats, for phenolic and acetate butyrate have been
molded around wooden cores for at least ten years. What is a departure is the distinct
trend toward all-plastics seats with ethyl cellulose, acetate butyrate and urea plas-
tics. Each of these newer offerings has its advantages and heavy retail advertising
backing them.

* < *

Not often, do you hear of injection molded thermoplastics replacing steel and brass
in precision mechanical parts. Silent running nylon gears, though, are showing real prog-
ress in electrical appliances, auto accessories and business machines. Despite higher
material cost per pound, the plastics gears are often cheaper than their metal counter-
parts, because of the care that must be employed in individually cutting brass or steel.
Extremely close tolerances can be held and the wearing qualities of the plastics surpass
those of the metal. One large business machine manufacturer is rapidly converting to
nylon gears for these reasons and because lubrication problems are eliminated.

Packaging of small mechanical parts in transparent, flexible vinyl or polyethylene
envelopes is a distinct trend. One manufacturer has recently introduced such a package
for pipe fittings. Such relatively costly little units are often scarred and marred in
pre-sale handling. The flexible plastics envelope they are now using eliminates that
problem and, more important, increases the unit sale by adding a sort of self -merchan-
dising appeal.

* * *

Heat resistant thermoplastics are making their debut in radio cabinets. Many battery
powered portable radios are now housed in inj ection molded thermoplast ics but their move-
ment into other types of small radios has been hampered by the need for higher heat re-
sistance. This was one of the principal incentives for the development of heat resistant
materials and several jobs are now underway.

SMALL PLASTICS articles are too difficult to polish
by a regular buffing wheel process, and the finishing
cost would be prohibitive. To finish such items economical-
ly, the barrel tumbling process was developed.

Both thermosetting and thermoplastics materials may be
profitably finished by this method. However, thermoplastics
are usually injection molded, and the only rough spot on a
piece would be where the gate is trimmed from the molded
part. Some very small thermoplastic parts have been pol-
ished by tumbling when the slight mark left by the gate was
objectionable and had to be removed. However, this is an
unusual rather than a regular practice. It is with thermo-
setting plastics that tumbling is the common means of
removing flash and polishing.

The only limitation to its use is the size of the piece.
Obviously, articles measuring over 3" in length or diameter
would be done faster and more economically by means of a
wheel. Sometimes a piece will be too intricate or too
delicate for the tumbling method; such parts are best fin-
ished by hand. Parts with a number of inserts sometimes
are hand finished because the insert holes and threads load
up with the polishing compounds, -which then has to be
removed by hand anyway.

Most thermosetting articles, when removed from the
mold) have a "fin" or "flash" attached. These pieces are
allowed to accumulate until a quantity enough for a "load"
is built up. Tumbling barrels should be loaded to a line
slightly below the center of the barrel for best results, be-
cause that allows the parts enough free space to fall about
and tumble. The parts are then dumped into a wire screen
receptacle called a definning barrel. This is rotated at a
speed of 20-40 rpm. Tumbling against each other and
against the barrel screen, the articles tend to clean them-
selves of flash which, being very thin, breaks off easily and
falls through the wire mesh which retains the molded parts.

It is a fairly common practice to add such things as
wooden balls, ball bearings, metal jacks, pieces of chain or
smooth stones to the load to cut down the definning cycle.

Operation Time Varies

The time that the operation consumes depends upon the
size and shape of the piece, the material of which it is mold-
ed and the thickness of the flash. Parts of simple design
produced in well-designed molds defin themselves readily.
Pieces of intricate shapes with several angles and identa-
tions, turned out in molds that have been abused, take a long

POLISHING SMALL PARTS

Several castings of a phenolic part, at the Waterbury
Companies, with the same parts tumble finished (below)

time to clean, as the flash is heavier than usual and is
located in places not readily accessible.

Brittle flash, such as occurs on urea and phenolic parts,
separates from the piece quite easily. Flash on parts made
of canvas or flock-filled material tends to hang on tenacious-
ly and never cleans off really satisfactorily. However, parts
made from this type of material are purely utility items or
are large enough for subsequent hand operations, so this is
not too objectionable.

Some manufacturers allow pieces to tumble long enough
for definning, and then place wet cloths or damp sponges in
the definning barrel to remove dust from the parts.

The pieces are now ready for intermediate polishing,
which is accomplished by either dry or wet tumbling. If
the parts were molded carefully in well-designed molds, or
have been machine finished, they may be dry polished.

Dry Polishing

This is done by. loading the pieces in a hardwood barrel,
either hexagonal or octagonal in shape. The barrel should
be loaded to just below the center line with approximately
three parts shoe pegs (obtainable from manufacturers of
tumbling equipment), two parts of molded articles and ^2
to one Ib of fine pumice powder. A pint of paraffin base oil
should be poured over the load. The lid of the barrel is
clamped on tightly and the unit allowed to revolve at 10-50
rpm anywhere from two to 20 hr, depending again upon the
size, shape and material of the part. It is impossible to
make any set rules and regulations unless the particular part
is under special consideration. Experience and experi-
mental equipment are the best means of formulating rules on
time or tumbling speed.

After the pieces have been well ashed, they should be
loaded into a barrel with sawdust that has been dampened
with kerosene. This will remove all traces of abrasive from
the parts. They are now ready for the final polishing.

The pieces are now loaded into a hardwood barrel with
wax treated pegs about 50 percent parts, 50 percent pegs.
A cup of patented polishing cream is added and the barrel

added and. the barrel run for two or three hr (again size
and shape of the parts are to be considered). After this,
another l /2. Ib of chalk is put in.

Par.ts are now placed in a barrel with wax-treated pegs
and allowed to rotate slowly for several hours at about 10
rpm. A check must be made often as a point may be reached
where more tumbling is detrimental rather than beneficial.
When the parts are lustrous, the load is removed and the
pegs separated from the molded parts. This may be done
on a mechanical shaker screen that has holes slightly
smaller than the molded items, but larger than the pegs used.

Pegs Must Be Cleaned

Pegs cannot be used indefinitely, but must be cleaned by
placing them in a barrel covered with fine mesh screening
and introducing live steam to remove the dirty wax. The
wax may also be removed by a solvent method, but this is
quite costly and more dangerous. When the pegs are clean,
they are dried by tumbling in a fine mesh barrel and blow-
ing warm air on them.

Pieces that have heavy flash or are rough should be
polished by the wet method. The barrels used for this pur-
pose are usually made from cypress and are the same shape
as those used in dry polishing. Naturally, they must be

watertight. Fine pumice should be added to the water and
parts, and often gravel or steel shot is also part of the load
Jo speed up the abrasive action.

Barrels should be run at 20-40 rpm for about 45 min, after
which the parts are removed and washed thoroughly with
tepid water. Polishing is done by the same means described
in preceding paragraphs.

Tumbling gives a good uniform finish unobtainable by
hand methods, saves considerable time and thus brings down
the cost per unit. Every molded part has its own individual
problems. A button, for example, would have to be handled
differently than would a piece 1" X 2". The proper equip-
ment for a particular item is best determined in cooperation
with the tumbler manufacturers, who must be provided with
a quantity of moldings to test in their laboratory equipment.
Then can then advise the particular type of barrel to pur-
chase and what formulas to use in polishing.

However, the general rules set forth in this article will
serve as a fundamental basis for setting up a tumble finish-
ing department.

What has been said so far applies particularly to molded
phenolic parts. Something needs to be said now on the
tumble finishing of cast phenolic parts, for it is a specialty
all its own. The data given here are based largely on the

Cast phenolic percolator handle, sliced from long casting, ready for matte finish. Plastics scrap, pumice and hardwood saw-
dust go into tumbling barrel. (Right) wooden or plastics balls may be used instead of plastics scrap in foregoing combination

experience of Creative Plastics Corp., Brooklyn, New York.
The procedure used by that company is described as they
finish a percolator handle.

The piece is sliced from a long casting which is covered
with a "skin." To remove this, a mixture of hardwood
sawdust, pumice and pieces of scrap plastics is placed in the
tumbling barrel with the handles. The scrap is used be-
cause on large pieces such as this the quiet undulatory
action of the barrel would only affect the flat surfaces. The
small bits of scrap work around on the inside of the handles
and at the same time keep them from banging against each
other and chipping. Instead of the scrap, plastics or wooden
balls may be used.

Besides removing the skin and giving a matte finish, this
operation also removes light tool marks such as those made
by the abrasive wheel, and it rounds the corners to some
extent.

Loading Must Be Accurate

The barrels must be loaded to just the right degree. This
varies with the parts to be tumbled and is pretty much a
matter of experience on the operator's part, for each job
requires different loads. Another decision he has to make
is whether to tumble wet or dry. Wet tumbling is done in
a large cast iron barrel when the maximum abrasion in the
shortest possible time is desired. However, this is not re-
sorted to very often.

Two barrels are reserved for this first tumbling stage as
against eight used in the ensuing polishing operations.

The next step is the waxing of the surface, which corre-
sponds to the brushing action in polishing shoes. Here the
variety of possible materials is almost endless, but one of the
most favored combinations at Creative Plastics is shoe pegs
and special wax-impregnated sawdust, which imparts a com-
paratively smooth finish to the object.

To achieve a completely finished piece, it is next put
through a polishing operation with dry sawdust and pre-
cipitated chalk. No appreciable cutting of the surface takes
place at this stage. Various tumbling experts use a wide
variety of other compounds during this operation, once
again depending upon the size and shape of the particular
piece.

The barrels, tilted forward slightly, are emptied with a
hoe. The mixture is dumped into a wooden screen which
permits the excess compound and pegs, sawdust, etc., to fall
through, and the polished pieces to remain behind.

Some firms use barrels mounted on stands in a double-
decker arrangement; others, like Creative Plastics, find the
horizontal arrangement better. Polishing compounds are

stored directly in front of each barrel so they will not have
to be transported any distance.

In order to get rid of the whitish cast imparted by the
pumice, the parts are rolled in a mixture of sawdust and
light oil. This in no way affects the finish, and it gives the
part a more pleasing feel and appearance.

Kerosene and other oils are used to achieve special fin-
ishes, such as a satin gloss. Small pieces of cloth, chamois,
rubber and other assorted materials also create special
effects.

Fixing the price for tumbling is a most difficult job be-
cause the cost will vary so much with the object being
tumbled. Generally speaking, a part will only require a few
hours in the matte finish barrels, but it may take a week or
even longer in the polishing operations. Small objects are
far more easily finished, and in the case of balls and other
rounded objects, the polishing time is greatly reduced.

On the other hand, these often require considerably more
sorting time by operators after removal from the barrels.
Sometimes the parts are so small that they cannot be suc-
cessfully screened and much time is consumed sorting them
out. Large objects such as gear shift knobs, which may run
only four or six pieces to the pound, tend to wear out the
wooden lining of the barrels very fast. Besides, not many of
them can be loaded into any given barrel at one time, so that
here there is a loss of productivity.

Accordingly, Creative Plastics makes no attempt to break
down a price 'for tumbling. They simply have established
how many pounds go through their barrels in one year at a
cost of X dollars for labor and X dollars for compounds.
Generally, the charge for tumbling is so small that the job
is seldom lost by the slight difference of a penny or two it
would make either way to set up a different formula for each
size and shape. Nevertheless, other firms have established
prices ranging from 20 to 200 per Ib for tumbling, some
were set after exhaustive research, but most were set by
guesswork.

It is important for people to realize what they get in a
tumbled product. For instance, very small objects must be
tumbled, and round objects will achieve a tumbled finish
every bit as good as or superior to the best hand polished.
On the other hand, flat surfaces should be hand polished,
because in tumbling it is almost impossible to keep the parts
from rubbing together and chafing. This is particularly true
in the matte finish operation. Two flat pieces of any appre-
ciable weight will rub together and the pumice will tend to
scratch the surface. Different grades of pumice are avail-
able; the best Italian grade cuts faster with a minimum of
scratching. END

Next step is waxing of handle surface. Here, wax-impregnated hardwood sawdust and shoe pegs give smooth finish, while han-
dle also picks up luster. (Right), the completely finished product. Dry sawdust and precipitated chalk were used (

An interesting combination of rigid sheeting with extruded
acetate in a Dubonnet basket made for Wm. A. Greca Co.

Fabricators Create
Sturdier Containers

THE DEVELOPMENT of a new method which con-
tributes strength and rigidity to decorative containers
provides evidence of the great interest in the fabrication of
rigid plastics sheeting.

As applied to the seating of container bases made of rigid
sheeting, the method developed by C. M. Tacopina, of
Dubonnet Products Co., Brooklyn, N. Y., varies from
the two types of procedures now in use. These are the
folded or drawn bottom, in which the side or cylinder walls
are seated, and the bead-seated bottom. On occasions crimp-
ing of side-walls to bottom is also used.

Mr. Tacopina designates his technique as the "retaining
wall reinforcement." A retaining wall is first cemented to
the lower edge of a blank which will form the walls of
various shapes of containers cylindrical, square or heart-
shaped. Hot-blade creasing to effect corners in the body
of the container is done through blank and retaining wall
simultaneously. After the body has, been seamed, it is seated
on another blank which forms the bottom and is cemented
to it. The cementing agent commonly used in this and other
cellulose acetate rigid sheeting applications by Dubonnet is
methyl cellosolve, although acetone is also used, but less
frequently.

The new technique when compared with the old reveals
that its retaining wall design offers twice the bearing surface
of the body on base. In addition, since there is no folded
edge that can flex, the whole construction is stronger and
more rigid, although it is slightly more expensive.

The retaining wall construction is now used extensively
in many container forms which are manufactured by the
Dubonnet Company. END

8 YEARS FRESH... BECAUSE OF PLEXIGLAS

Pouring rain, freezing gales, blistering sun for 8 years this big Plexiglas bread loaf has
withstood them all without deterioration! Built and erected in-1940, it has had only minor
repairs. Yet today it gleams like new, and the original interior paint is in good condition.

PROTECTION -Indoors and Outdoors

Indoors or outdoors, Plexiglas signs last indefinitely.
They're sun-proof, weather-proof, virtually unbreakable
and even age does not discolor them. The Under-
writers' Laboratories have approved its use in many
electric sign installations.

STRONG-LIGHT-Easily Formed and Decorated

Plexiglas is a thermoplastic acrylic resin, easily heated
and formed into any shape desired. It can also be sawed,
routed, drilled, threaded, turned or milled, just like wood
or metal. Weighing less than one-half as much as silicate
glass, it is surprisingly easy to handle and install, and
since it is rigid and self-supporting often requires no
frame or reinforcement. Designs may be applied by
carving, engraving, painting or silk-screening.

LASTING TRANSPARENCY -Attractive Colors

In its natural state, Rohm & Haas Plexiglas is colorless
sparkling and clear as fine optical glass. There is an,
interesting choice of attractive colors for Plexiglas signs'
transparent or translucent as well as black or
white opaque.

When It's Plexiglas It's A Good Sign

For signs that are lighter, stronger, longer-lived and more
attractive, choose Plexiglas.

It combines readily and beautifully with woods, metals,
and other plastics. For additional proof, write today for
our new brochure "Plexiglas for Signs." You'll enjoy
reading it.

A RADIO-PHONOGRAPH combination which uses

is in production at Remler Co., Ltd., San Fran-
cisco. The combination of thermoplastics for decorative
pieces, such as the grilles, feet and lid, with thermosetting
parts where strength is required, as in the case and motor

machine, according to Robert C. Gray, president. Although
it is one of the smallest combination sets on the market, with
a case measuring only 64" X 7" X 10". the machine plays

rene, urea, phenolic and acrylic, depending on the part and

Two chief reasons are given for this large-scale use of
plastics : ( 1 ) The firm is equipped to manufacture all parts
for the plastics case, including doing the molding as well as
the screw machine and punch press components; (2) It
found plastics easier to work with for styling; (3) It found
the pleasant feel of plastics materials desirable.

Polystyrene was utilized for injection parts because of its
decorative quality and heat resistance. Where heat resist-
ance alone was the major criterion, phenolics were chosen.
Where a white material of great strength was required,
urea formaldehyde was used.

the air. As cool in appearance as a mint julep, it would
be an ideal centerpiece for any terrace dining table.

With The Toy Merchants

Another famous New York institution, popular with
the younger set since 1862, is the F. A. O. Schwarz Fifth
Avenue toy store. Probably the largest store in the world
devoted exclusively to toys, Schwarz has literally hundreds
of plastics playthings in its vast stock. These range
from cellulose acetate rattles for the baby to technical
sets which teach the growing boy how to become a
plastics engineer.

Because of the ease with which they may be cleaned
and their bright range of colors, plastics toys have been
popular for babies for a long time. However, there are
new developments, even in rattles. Now they come in
complete sets which include three balls, each in a differ-
ent color, an old-fashioned rattle with a substantial
handle, and a tiny plastics bluebird in a cage which
clips on the side of the carriage or playpen. And if
Baby isn't happy with all that, he may have a fascinating

plastics fish which winds up with a rubber band and flips
its merry way around the bath tub.

The young child has an amazingly wide variety of
plastics toys to choose from. There are husky toy. auto-
mobiles with wind-up mechanism, for instance, 8" and
10" long, with a strong phenolic exterior built to with-
stand all the wear and tear that Junior can devise. One
of the best toys for the five-to-nine-year group is a
21" mechanical speed boat, its authentically detailed
hull built entirely of shining plastics. Then there are
plastics dolls, trains, tiny sets of furniture which are
replicas of their grown-up counterparts. The list is
virtually endless.

The technically-inclined child of nine to twelve has
not been forgotten by the playthings makers, either.
New this year is a plastics "set" which teaches him how
to make his own plastics materials. And, if his interest
goes still further, he may have a miniature molding
machine with which he may make his own toys. There
is an intricate plastics building set, too, which enables
the child to duplicate actual buildings to scale, -)4" to
the foot. This set is so accurate that Father could well
borrow it to build a pre-view of the new family home-
to-be.

Novelties might be defined as toys for grown-ups
(as well as children). The world's biggest novelty store
would be likely to prove to be Shackman's, at 34th St.
and Madison Ave., just a block away from the Empire
State Building. This extremely interesting shop, which
provides materials for parties from Manhattan to Malibu,
has thousands of plastics novelties. Some of them are
humorous, like the pretend false-teeth which can com-
pletely alter your appearance in a second, or the plastics
eggs which are realistic enough to fool even the most
skeptical hen.

Wholly decorative in purpose, this "lamp" consists of a
beautifully carved block of acrylic plastics which is base-
lighted and by its light-piping properties provides a re-
freshing, urtistic expression. Model is priced at $23.50

Virtually all-plastics corner, on second floor at New York
store of F. A. O. Schwarz, shows how sturdy, quality toys are
merchandising with plastics materials as essential components

Plastics in Tiny Novelties

Shackman's specializes in children's novelties, too.
many of which are used as favors for birthday parties.
These must necessarily be small, and among them are
miniature masterpieces. Did you know about the plastics
toy train, an inch wide and an inch high, four cars long,
that actually runs? There is such a thing, and you can
see it at Shackman's. They have a miniature moving van,
too, about four inches long, which is complete with a full
load of lilliputian furniture which may be removed or
replaced. The whole thing van and furniture is made
of cast phenolics. In the same miniature vein are replicas
of refrigerators with removable "food" inside, tiny
automatic-type clothes washers that actually open, little
stoves none of them more than 3" high, all of them
plastics.

Vinyl film provides the material for countless in-
flatable toys chickens, ducks, dogs, cats, or almost any
other animal you can think of. And of course there
are all sorts of inflatable vinyl film balls.

Among the larger toys at Shackman's are plastics
harmonicas that play as well as the old-fashioned kind.
There are other musical instruments, too, which must be
hummed into polystyrene saxophones, trombones, trum-
pets and various other horns. Not exactly musical, but
still in the noise-making category, are the plastics
whistles, some weird, some startling, which are featured
for the more energetic party.

New York is the center for stores which specialize in
one particular material. Dennison's, for example, is
noted principally for its paper products; but it, too, has
an interest in plastics. One of its new items is a plastics-
coated, fibre-backed paper which may be used in place
of oil-cloth for shelf-lining. Tough, untearable, heat-
resistant, it wears remarkably well and is much less
expensive than oil-cloth. Plastics-coated paper is used
for place mats, too, and a heavier paper resembling
cardboard, laminated with plastics, makes coasters.

Even Georg Jensen, whose Fifth Avenue shop is fa-
mous for its hand-wrought silver, uses acrylic plasters
to form the handles in a sterling fork-and-spoon salad
set of exquisite design.

Lewis and Conger, which can provide almost any
household item, has many conventional plastics items.
One of the less conventional, however, is its stock of
transparent acrylic doorknobs, hand-decorated with
flower designs inset to add a note of color to any room
in the home.

What Do Store Buyers Think?

Plastics merchandise, as was ventured at the start of
this review, has a certain Cinderella-like character.
Items in which plastics play a major part are found, in
some form, in almost every fine store, whether it
specializes in toys, household goods, paper or hand-
wrought silver. But what customer reactions? What do
these store buyers think?

Department heads in each store mentioned in this
article were asked to express a frank opinion of plastics,
and in every case they spoke freely. The consensus of
their combined comments boiled down to this : Consumer
resistance to articles made of plastics is lessening to a
marked degree as post-war products improve, but it is
still present.

When plastics are used in new ways which fully utilize
the virtues of such materials, the customer is usually
quick to recognize it. But he is aware that plastics have
been misused, and he is learning to discriminate.

For example, the average customer now knows that
acrylic surfaces which are exposed to constant scratching
(as in the case of eating utensils, cigarette boxes, table
tops) will soon become dead and dull in appearance.
The store buyer knows this, too, and there is strong
resistance all along the line to this sort of merchandise.
Some of the newer acrylics are much more scratch-
resistant than were pioneer varieties; but, because the
new and the old still look alike, there will have to be
a program of education for the public and the store
representatives to set up a new group of acceptances.

Some of the more flagrant misuses of plastics, such
as the fruit-juice extractor which withstood everything
except lemon juice or the acrylic ash tray which emerged
with a hole after a cigarette had been snuffed out against
it, were the result of carelessness in research on the part
of the manufacturer, according to one buyer. He also
'blamed mistakes of this type on producers of raw ma-
terial who were over-anxious to sell their product, and
sold it without consideration for the manner in which
it was to be used. We all know that this situation has
been rectified quite largely but the memory sometimes
lingers on.

One startling fact, which is also most disturbing, is
that store buyers, as a group, know almost nothing about
the technical side of plastics. The buyer for one large
store who was asked if, when she selected plastics goods
for her store, she knew whether it was made of the best
plastics material for the purpose for which it was in-
tended, said, "No, I don't know one plastics from an-
other. I buy it if it looks good, and if it isn't returned
by the customer, I figure it must be all right. If it comes
back, I know I've made a mistake."

Now that the plastics industry has gained a firm foot-
hold in the world of high-styled merchandise, it seems
evident that, if it wishes to continue to improve its stand-
ing with reasonable speed, it must find a way to teach
store representatives the virtues of well-designed, well-
planned goods. When real advancements in plastics are
made available to the buying public, the promotion of
even the most desirable goods will mean little, or will

be greatly retarded, if store buyers are not trained to
recognize improvements when they see them.

That is the first step. Then, when the store is able
to give factual information direct to the customer, he,
too, will increase his knowledge of what plastics can do
for him and how they are best used.

motor, since styrene will warp at about 180F. A combi-
nation of ventilation and safety devices provided the
solution which was approved by underwriters.

Thirteen symmetrical holes were molded into the base
of the set, louvres were built into the motor board, and
both the front and rear grilles add to the cooling by virtue
of their design.

For greater safety, the turntable switch was built onto
an extension pickup arm, so that the motor cannot run
except when the arm is extended to playing position. In
this position, the lid will not close.

The major production problem of the radio cabinet arose
from the differential shrinkage of black and white parts.
This was overcome, according to Wayne Becker, tool en-
gineer, by developing two sets of inserts in the mold of
the case. This made it possible to set over slots in the mold
to compensate for the greater shrinkage of black phenolic
over white urea in producing a black and white model.

An all-white, an all-black, and a black and white model
are currently in production. (Brown parts are used inside
the machine.)

At first, all-plastics hinges were used, but these were
not entirely satisfactory and were replaced by larger
hinges, still made of plastics, but strengthened with a
steel pin, designed as part of the polystyrene lid and
rear grille. To bore the hinge holes, a drill press is used
which bores from both ends simultaneously, one from the
top and one from the bottom, while the lid is held in a spe-
cial vise. The styrene rear grille is molded with pin in-
serts another time and cost saver in production.

Assembly of the cabinet with spring steel speed nuts is
a time saver. The speed nuts are installed with a gravity
hammer to avoid the danger of cracking the urea or phe-
nolic if the nut were pounded home. In the entire assembly,
only one rivet is used. It holds a catch spring for the lid.

Another sizable economy is achieved by producing the
dials in much the same way as newspaper mats are made
from electrotypes. From a master brass photo-engraving
on which the dial figures were etched, an electrotype was
made. This is heated in a 20-ton press to 140-160 F,
and a ribbon of color is inserted between it and the acrylic
dial, on which the electro then punches the figures.

Before Remler hit on that embossing process, it had
experimented with molded figures, silkscreen and a num-
ber of other procedures. Molded figures, besides being more
costly, were distorted because of non-constant shrinkage
of the acrylic. Because the dials contained concave angles,
silkscreen was mechanically too difficult to apply.

Each plastics part gets a test assembly every time a
new batch of mix is -molded. Thus minor unanticipated
shrinkages, which sometimes occur in new mixes supposed-
ly the same as the master batch, can be spotted and cor-
rected before production of an ill-fitting part gets too far
underway. Although this testing procedure would seem to
slow production, the company finds that, on the contrary,
it actually speeds up production by preventing waste.

For its molding, Remler uses an 8-oz Reed-Prentice
and a 16-oz HPM injection press, a 150-ton HPM com-
pression press, and several semi-automatic, self-contained
hydraulic presses of its own design, ranging in capacity
from 60 to 350 tons.

Radiowise, the machine contains five miniature tubes
plus a selenium rectifier and a 4" X 6" oval speaker.
Two of the tubes are audio output tubes hooked up in
parallel to give the set strong volume. A gear-driven
motor is another feature.

EMBOSSING ACRYLICS

Relatively simple fooling procedures and materials have been developed for
embossing thermoplastic materials on a custom basis. Using the metal-forming
technique with thick, hard, rubber pads and a casfable plastics composition
as the embossing medium, individualized decorative pieces may be achieved

y (7' tn

Technical Director
Plastics Industries Technical Institute

EMBOSSING offers a method of enhancing the decora-
tive appeal of acrylic and other thermoplastic mate-
rials. Within the past year, materials manufacturers have
put such sheets on the market in various pebbled and grained
surfaces of some repetitive design. However, just as it is
impractical to maintain too varied a color assortment of
sheet stock, it may prove inexpedient to make up too large
a variety of embossed surfaces, so that individualized de-
signs will have to be produced on a custom basis. For this
type of work, relatively simple tooling procedures and
materials have been developed by the writer. By making
use of the well-known metal forming technique with thick,
hard rubber pads and a new, hard, castable plastics com-
position as the embossing medium, individualized decora-
tive pieces may be achieved.

The fabricator first reproduces his design in a suitable
modeling clay. While there is no restriction on the amount
of detail he may incorporate in it, he must limit the depth
of the design in view of the fact that it represents the depth
of detail in the final embossing, and too many deep cuts
are apt to weaken the piece.

Over the clay model Calcerite is poured. This casting
material, made by Furane Plastics and Chemicals Company,
Los Angeles, will capture all the details of the clay model
and will serve as the actual embossing medium. Unlike
other synthetic resins, Calcerite has the cardinal advantages
of being able to cast against clay without sticking or absorb-
ing any of the oils, and will set up at room temperature in
about 30 minutes. For added toughness, it is desirable to
reinforce it with cotton flock. One may consider special
gypsum plasters in this same category, though it has been
our experience that they will fail or crumble under the
embossing operations fairly quickly.

Embossing Procedure

After aging overnight at room temperature, or in an
oven at 120-140 F for a couple of hours, the Calcerite
embossing tool is ready for use. The acrylic sheet to be
embossed is heated to about 300 F, placed on the tool,
and is in turn covered by a thick hard rubber pad (about
70 Durometer). The set-up is then placed in a small

PLASTICS DICTIONARY
By Thomas A. Dickinson

This book defines some 3,500 terms used in the plastics and
related industries, including also a good many trade names
of American and foreign materials and processes. In the case
of plasticizers, solvents, pigments and some other words, the
definitions are supplemented by charts. For the most part the
definitions are admirably clear; they are never so brief as to
be congested or to require looking up another word to make
the meaning plain.

Oddly enough, the definition of so basic a word as "poly-
mer" "it is made by combining the atoms of simpler sub-
stances, etc." is not satisfactory, though "polymerization"
and "polymerize" are quite accurately defined. There are
some other minor slips, such as setting down '"Polythene" as
a trade name when it is only DuPont's abbreviated form of
polyethylene. By and large, though, this is an excellent and
timely book and a useful addition to any reference shelf.

Contest entry drawings may be in any medium and arran
in any way on 20 by 30 sketch boards or the equivalent. E
piece must be shown in sufficient drawings so that the piece
be built from these specifications. Scale of drawings is optk
but must be clearly indicated. Competitors are required to s
a working model of each seating or storage unit submitted,
less than one-half full size.

The best designs for a seating unit and storage unit will e
be awarded $5,000 first prize, $2,500 for second, and $1,25C
third prize.

G-E Markets Si/icone Compounds

Immediate marketing of seven standard grades of silic
rubber molding compounds to molders and fabricators is
nounced by the Chemical Dept. of General Electric. All sto
withstand temperatures ranging from minus 70 to plus 520'
and have excellent electrical and chemical properties.

Stocks include both molding and extruding compounds, wl
may be readily processed in standard production equipment, v
various grades available in white and brown.

The company recommends that the molding compound be [
milled for about 10 minutes on cold rolls prior to molding to
sure satisfactory flow and plasticity. Company says mold
should be performed at low pressures in standard compression
transfer molds and that the mold design should allow for ab
two to three per cent dimensional shrinkage on curing. Flash t
molds give the most satisfactory results at pressures not exce
ing 100 psi whereas positive or semi-positive molds are usu;
operated at 400 to 500 psi.

Molding temperature for this silicone rubber should be 140 C
160 C and should be maintained for two to 10 minutes depend
on the size and cross-section of the piece. It is recommended t
molds be loaded and unloaded at temperatures below 50 C
prevent blistering and porosity in the molded piece.

Extruding of silicone rubber stocks is performed in eit
short or long barrelled production machines but the latter
preferable according to General Electric. Accurate control
extrusion speed and die temperatures results in better surfa
and closer dimensions for the finished product, it was s;
Die design should conform closely with the shape of the finis!
part.

Now used principally as gaskets in various types of industi
equipment, the material has such advantages as heat resistar
non-adherence to metal surfaces, good gasketing action beca
of low compression set and stability of surface hardness <
resilience. The materials do not tend to cold flow nor vulcan
at room temperature, it was said. Stocks can be reinforced
additional strength.

New Drying Tower

A novel drying tower used in the production of coated fabrics
by Siemens-Schuckertwerke, A. G., Germany, is described in a
short report now on sale by the Office of Technical Services,
Department of Commerce.

The manufacture of polyvinyl chloride fabrics and films by
use of a paste dispersion method as described in the main report
is considered by American investigators as being the most out-
standing development in the German coated fabrics industry.
The resin, plasticizer, and pigments were mixed together, applied
in the form of a paste and then fused under high heat. The
process produced a tough, flexible film or coating.

The drying tower described in the supplementary report is
heated by steel heating coils through which hot water is circu-
lated. The coils are designed to withstand pressures of about
five atmospheres, and operating temperatures up to 150 C are
possible, the report states.

"Seofed-in" Printing on Vinyls

Sealing-in of colors both in topping and printing on heavier
gauge vinyl sheeting by a new process is announced by the
Plastic Printing Corp., formerly of Brooklyn, N.Y., now at 239
East 56th St., New York. The company is applying a gold
topping which is so infused with the material that it becomes
possible for the first time to press-polish, as well as emboss, after
application of the color.

Acetate Fibers Not Rayon

Tennessee Eastman Corp., subsidiary of the Eastman Kodak
Co. and a producer of cellulose acetate textile fibers, has an-
nounced that it has discontinued use of the word "rayon" as a
generic name for its fibers and the products made from them.

In explanation of this decision, the following statement was
issued by James C. White, President and General Manager of
the corporation:

"Two very different textile fibers are now being offered to
the public as 'rayon'. One of them is known chemically as
viscose, or regenerated cellulose, the other as cellulose acetate.

"Today these two man-made fibers may be found in retail
stores in the same types of apparel and home furnishings, such
as women's dresses and underwear, men's suits and shirts,
linings, bedspreads, curtains, and upholstery. Viscose and cel-
lulose acetate differ widely in most physical and chemical prop-
erties of importance to the consumer. They are not interchange-
able in any use with the same degree of serviceability. They are,
in fact, about as unlike as any two natural fibers one could name
in such critical qualities as moisture absorption, shrinkage, resist-
ance to wrinkling, soiling, mildewing, ease of washing and iron-
ing, and ability to hold an ironed-in crease.

Dow Re/eases Saron Trademark Rights

Formal release of trademark rights to the name "Saran" per-
mitting it to become the descriptive name for the product has
been announced by Donald Gibb, head of plastics sales divi-
sion of the Dow Chemical Co. This action was taken "in the
interest of simplifying identification on various plastic mate-
rials whose chemical names have for years been confusing to
press, trade and consumer alike," according to Mr. Gibb.

The term saran applies to a series of thermoplastic resins
chemically known as vinylidene chloride copolymers originally
developed by Dow in the latter thirties and known especially
for their resistance to a wide range of chemicals. Monofilaments
of the plastic are currently becoming prominent in the textile
field. Moisture repellent packaging films and corrosion resistant
piping are other important uses of the plastic.

How Vinyl Film Reaches

the Retailer

The channels through which vinyl products
move from resin manufacturer to point of
sale are now becoming clarified. For the
first time it is possible to graphically
present the functions which are carried
out at each step, and to describe these
relationships, often overlapping, which
control activities of particular firms.
Here is this picture as it now stands

BASIC FUNCTIONS are carried out in the
moving of vinyl film and film products to the re-
tailer. Four of these are manufacturing operations in-
volving materials and products while the fifth is purely
merchandising in nature.

Base Resin manufacture is the first of these steps.
In this operation various chemical components are re-
acted under very carefully controlled conditions to yield
the basic material. This may be any one of several types
or closely related to the chemical compound known as
vinyl chloride. By its nature this operation requires the
backing of a strong research organization and the appli-
cation of precise technical control and involves massive
plant equipment. It is economical only on a large scale.

In order to yield the properties which are desired in
vinyl products, the base resin manufactured in the first
step must be modified by the addition of plasticizers
and other components an operation known as corn-
founding.

Vinyl Film Manufacture

Vinyl resins are used in many different ways, but
for the products concerned here, film manufacture is the
next step. This involves the production of continuous
lengths of film from resin compound by one of two
processes calendering or casting. The word "film"
refers to such calendered or cast materials, whereas the
word "sheet" refers to single plates or pieces produced
by other methods.

Film so made may be in the natural transparent color
of the vinyl or it may be colored or pigmented. To an
increasing extent though, the film is given further
styling by the application of patterns or textures.
Such finishing may take the form of printing, embossing
or graining.

Fabricating is the end of the production chain.
While both plain and printed film are sold as
piece goods over the counter, the greater amount of
film moves to fabricators who process it into the host
of products now made of vinyl film raincoats, shower
curtains, bowl covers, etc. Film also moves for fabricating
into old-established manufacturing industries such as
those making handbags, upholstered furniture, leather
goods, shoes and automotive products.

Although the flow of vinyl film through various
manufacturing steps appears very simple when laid out
in a straight line, the commercial relationships that have
grown up are exceedingly complex. Many companies,
for instance, cover more than one function, and numerous
special arrangements exist among the companies per-
forming the basic functions.

In the basic position are the manufacturers of resins.
By the end of this year, there will be a total of seven
companies in this country manufacturing resins of the
vinyl chloride or modified vinyl chloride types. These
companies make resin not only for film but also for
molding compounds, extruding materials, surface fin-
ishes and adhesives. Some of the base resin manufac-
turers carry out the compounding function as well, but
one of these companies confines itself to manufacture
of the base resin. Independent compounders secure their
resin from these companies and may also from time to
time rework scrap material.

Turning Vinyl Resins Into Film

Film manufacturers, of whom there are over twenty-
five at present, but either base resin or resin compounds
and turn it into film. Some of the resin manufacturers
also devote a part of their production to film, in addition
to selling resin or resin compound to affiliated companies
who manufacture film.

The finishing operation printing or texturing may
be carried out by one of several different kinds of com-
panies. Some film manufacturers, for instance, carry
through to that operation and do the desired finishing.
In other cases, independent finishing plants carry out
this operation either for their own account or on a custom
basis.

The fabricator therefore has available a number of
sources from which he can secure film. He may get it
from the resin manufacturing company, from the resin
company's affiliate, from a film manufacturer or from a
finisher. The fabricator operates either on a proprietary
or on a custom basis. In the first case, he creates and
designs his own ideas, in the other he does sub-contract-
ing for other accounts.

A more recent development is the entrance of the
converter into this already complex picture. (The word
"converter," as used here, is a direct carryover from
the textile field and must not be confused with either
a finisher or fabricator.) The converter does not set up
any manufacturing facilities: his functions are primarily
merchandising in nature. He is concerned primarily
with film goods that are finished in one way or another
by embossing, printing, etc. Beginning with plain
calendered film, he creates or chooses designs or surface
treatments which he feels have a market, assuring the
cost of printing rollers or other initial costs. He then
has a commercial printing or finishing plant perform
the operations on a contract basis, and sells the finished
film to fabricators and to retail outlets.

The function of merchandising to retailers is carried
out by virtually every factor in the field. The product
fabricator has the most direct relationship since he sells
his product to department stores, chain stores, and inde-
pendent merchants directly. The film manufacturer is
also concerned with this market since he sells a portion
of his production to the same organizations for resale
as piece goods and has an incentive to help his fabricator
customers do a sound merchandising job. The base resin
manufacturers are also very active in this field since
they are very much interested in promoting the growth
of the market and in building acceptance for their trade
names.

hydraulic press. The rubber forces the sheet into the em-
bossing die under pressures of about 300 psi for the
illustrated design, the pressure ordinarily being governed
by the temperature of the plastics, the thickness of the
sheet, and the depth and sharpness of the embossed de-
tails. Upon cooling, the sheet is removed, bearing the
complete original design. The same embossing tool may
be used to reproduce many additional pieces.

The process is simple, and the only added equipment
which a fabricator may require is a small press capable
of delivering 10 to 20 tons pressure if needed. Small
screw or arbor presses may be entirely adequate for small
designs. Metal tools are probably even better for em-
bossing. However, their cost is usually prohibitive, espe-
cially where designs have to be changed frequently and
only a few pieces are ordered of each.

From a larger production standpoint, the speed will
depend upon the rate at which the warmed thermoplastic
sheets will cool in the die. Presumably the die will get
too hot after repeated use and will have to be cooled down
if a rapid cycle is to be achieved. In that case a duplicate
die, which would not cost much, should be available to
maintain production. ENE

Kodak Opens Plastics Laboratory

Opening of a new plastics laboratory has been announced by
the Eastman Kodak Co. The laboratory, which is located in the
company's Camera Works in Rochester, N. Y., is equipped foi
a broad range of experimental studies. Kodak is using the
laboratory to intensify its development of plastic parts for
cameras, projectors and other photographic apparatus. The
project is under the general supervision of Garson Meyer, chief
chemist at the Camera Works who holds the designation oi
"Plastics Pioneer," awarded by the Society of the Plastics
Industry in 1944. Gerard Delaire is engineer-in-charge. A
"plastics parts museum" also is being set up in the laboratory.
This collection of hundreds of plastics products photographic
and non-photographic will aid Camera Works engineers in
studying how the other fellow uses plastics. While actual
large scale production of Kodak's plastics parts is done by
several custom molding concerns, the laboratory will enable
Kodak to solve quickly and scientifically many research and
engineering problems associated with the use of plastics in
photographic equipment.

Electric-Strength Properties

The intrinsic electric-strength characteristics of plastics are
unusually interesting, providing a comprehensive evaluation
of such factors as temperature variation, molecular weight,
degree of crystallinity, moisture content and general elec-
trical insulating effectiveness.

Thermoplastic materials have been ideal as bases of inves-
tigation, since they can be readily molded in a variety of
sizes, shapes and thicknesses for study. Particularly adapt-
able to an analysis is polythene, an excellent insulating
medium, particularly at high frequencies where close control
of physical structure and chemical purity are essential.

About a year ago, W. G. Oakes of the Imperial College,,
London University, England, began a series of intrinsic
electric-strength investigations with polythene as the base
material to be studied. The results of his work, presented
before the Institution of Electrical Engineers in London,
were quite revealing. Employing a series of d-c voltage tests
on recessed specimens, Oakes measured electric strength as a
function of thickness, time of voltage application, radius of
curvature and polarity of recess, ambient medium and elec-
trode material. In d-c tests at room temperature, with .002"
thick specimens, graphite electrodes and transformer oil as
the immersion medium, he found a linear relation between
thickness and disruptive voltage, test voltages ranging from
to 40 kv. Checking the effect of the radius of curvature,
Oakes found no significant change in the mean electric
strength when the radius was increased from .125" to .5".

Studying the effect of ambient media, with transformer
oil, liquid paraffin, pentane and hexane, it was found that at
room temperature with a 5-min immersion, the electric
strength was substantially independent of the type of liquid
used. Above about 50C, it was found necessary to use air
as the ambient medium, since liquids with suitable insulating
properties were absorbed by the specimen, leading to swelling,
and at higher temperatures complete solution of the poly-
thene.

In analyzing the effect of impurities on electric strength,
Oakes rolled polythene ("with a polar impurity introduced
chemically by oxidation) on an open rubber mill at 150 to
160C for five hours, took samples and found that electric
strength was not significantly changed by mild oxidation.
The extent of oxidation was measured in terms of the power
factor at 16 megacycles.

Oakes stated in his report that density and specific-heat
determinations, as well as x-ray analysis, have shown that
at temperatures below its melting point, polythene is com-
posed of inseparable crystalline and amorphous regions. In
the crystalline regions, it is believed that portions (in length
10~ 5 cm) of many molecules are packed side by side in
crystalline fashion. The amorphous regions consist of portions
of chain molecules which tie one crystalline region to the
next, together with some loose ends of molecules. In addition,
Oaks reported, there is evidence that the crystallites are
grouped together in clusters known as spherulites (in which
the molecular axes of the crystallites are perpendicular to
the radius of the spherulites), the size of which varies greatly
and may be quite large (diameter 10~ 3 cm). At room tem-
perature, the crystalline-amorphous ratio has been estimated
at about 75:25. Below 50C, the percentage of crystalline
material has been found to change slightly, while at higher
. temperature it decreases, becoming zero at the melting point.
Oakes believed that the spherulites decreased in size and
broke up as the temperature rose, disappearing almost en-
tirely in the molten state. These changes in physical structure

may be related to the electric strength, with breakdowr
being initiated in either the crystalline or amorphous regions
or in the intermediate regions between the spherulites.

Oakes prepared his polythene samples by placing 1" X 1'
X 1/32" sheets horizontally on a sheet of glass^held in a re
cessing tool, and heating quickly to 120 to 130C by placing
the tool on a hot plate. When the polythene melted, a stee
ball, J4" in diameter, was pressed down into it to leave :
film of the desired thickness between the ball and the glas:
plate; film thickness was controlled by mica spacers. Thi
recessing tool was then transferred to a water-cooled coppe:
plate, and after a few minutes the polythene solidified
Removal of the glass plate and specimen followed, the reces;
being examined by a polarizing microscope (magnificatioi
of 50). Specimens without optical strain patterns or em
bedded dust particles were used for the tests.

Fireproofing the Cellulose Molecule

Fireproofing of cellulosic fibrous materials, such as cotton
has been a research project of many labs. Inorganic am
organic compounds, oxides or easily reducible metals, product
containing halogen, etc., have been used as fire retardants
Louis W. Georges, Columbus, Ohio, and Carl Hamalainen
New Orleans, La., recently discovered that a plastics fire re
tardant can be chemically combined with the cellulose mole
cule, with the fireproofing effect being retained permanent!;
irrespective of washing.

The cellulosic fiber is reacted with a hot solution of
halogen substituted aryl isocyanate, such as a halogen suh
stituted phenyl isocyanate like 2,4,6-trichlorophenyl isocy
anate, in a tertiary organic base, particularly pyridine, t
form a carbamyl ester type of derivative of the cellulose.

The 2,4,6-trichlorophenyl isocyanate is prepared by sus
pending 50 grams of 2,4,6-trichloroaniline hydrochloride i
55 cc of chlorobenzene. Phosgene gas is passed through th
suspension in a steady stream with continuous stirring, durin,
which time the temperature of the reaction mixture is gradu
ally raised until the solvent begins to reflux. The phosgen
gas is then passed into the reaction mixture until the solutio
becomes clear. A small amount of a crystalline compoun<
(the disubstituted urea compound) appears, and must b
filtered out. The clear filtrate is then distilled in a vacuur
to remove the solvent. Hot residue is poured into a crystal
lizing dish and stored in a vacuum desicator where, upo
cooling, the 2,4,6-trichlorophenyl isocyanate crystallize!
These crystals, which will melt at 64 to 65 C, react wit
water in the presence of pyridine, resulting in a di-(2,4,6
trichlorophenyl) urea melting at 295C.

A 2,5-dichlorophenyl isocyanate compound can also b
used in the Georges-Hamalainen process. This is prepare
by suspending 45 grams of 2,5-dichloroaniline hydrochlorid
in 500 cc of chlorobenzene, and passing phosgene ga
through the suspension in a steady stream with continuoi
stirring, with the temperature of the reaction mixture gradi
ally raised until the solvent begins to reflux. The phosgen
is passed into the reaction mixture until the solution become
clear, and the resulting solution is stilled in a vacuum t
remove the solvent.

The residue is clear and colorless, boiling at 83 to 84i
at 3 to 4 mm pressure. This isocyanate also reacts with wate
in the presence of pyridine to provide a colorless crystallin
di-(2,5-dichlorophenyl) urea melting at 289C.

In preparing a sample, Georges and Hamalainen extracte
two grams of lint cotton with hot 95 per cent ethanol, an
then with hot one per cent sodium hydroxide solution. Th
cotton was then dried by adding benzene and distilling o
the water azeotropically. In the next step, 4.5 grams of 2,1
dichlorophenyl isocyanate compound (representing 2 mo.
of the isocyanate per glucose unit of the cotton), dissolve
in 100 cc of dry pyridine, was added to the dry cotton. Th
reaction mixture was heated in an oil bath for 22 hr at 122
to 125C. The cotton was then filtered from the mixturi
washed successively in fresh pyridine, ethanol and water, an
then dried in a current of warm air.

The resulting cotton, in which the cellulose was partiall
converted to 2,5-dichlorophenyl carb^mate, represented
sain of 233 per cent in weight over the unreacted cottoi
The fibers were coarse and stiff, but resistant to burning.

The Northmaster Intensive Mixer, designed for mixing all
types of heavy and tenacious materials, is available in working
capacities of from one pint to 275 gal, and has been used suc-
cessfully for processing a wide range of plastics products, as
well as rubber, asphalt compositions, paints, etc.

Equipped with heating or cooling jackets for ram, trough and
blades, the machine incorporates anti-friction bearings with in-
tegral gear unit attached to the trough and rotating with it.
Xew metal-to-meal seals guard against leakage. Mixing cham-
ber is -liquid- and dust-tight, and rotates through lcSO to permit
easy dumping and cleaning.

moisture-proof 'film has been moving entirely into the foot pack-
aging field. A. F. Landefeld, manager of the I'linfilm sales
department of Goodyear's chemical product! division, said that
initially availability will be to pre-war fabricators of I'linfilm.

Portable Glass Electrode pff Meter

Beckman Instruments. National Technical Laboratories
820 Mission St., South Pasadena, Calif.

The recently announced Bcckman Model II Meter, a portable
glass electrode pH Meter which is said to combine accuracy
and versatility with the convenience of full AC operation, can
be plugged directly into any standard 110 volt S0/n() cycle AC
line, and can be easily transported from one location to another
or installed permanently.

The new unit covers the full scale of to 14 pH, and can
also be used for making millivolt readings within the range
4 to 410 millivolts.

A built-in temperature compensator dial calibrated to 100 C,
which can be set at the temperature of the test sample, automati-
cally adjusts the measuring current to compensate for the effect
of temperature on the KMF of the glass electrode, thus insuring
correct pH readings without calculations or reference to pH-
temperature charts.

The Model H instrument measures 12" X9 l / 2 " XS'/j" , has a
net weight of 14 In, and a power consumption of ,!5 watts.

PLASKON MOLDED COLOR!

7"A/s line of dinnerware is molded by the Bryant Electric Company, Hemco Plastics Division, Bridgeport 2, Connecticut.

Hemcoware now brings a colorful new note of attraction to home dining tables. For breakfast, lunch, dinner or late
snack, Hemcoware lends its many distinctive features to the needs of the occasion.

Hemcoware is molded from a thermosetting PLASKON molding material which will not become soft or lose its shape
under ordinary conditions of heat in home service.

Hemcoware can be washed in any type of dish washer, and is not affected by any of the standard types of soaps or
commercial washing compounds. Hemcoware is odorless and tasteless important advantages of Plaskon Molded
Color in all applications where flavors or odors must not be contaminated. Because molded Plaskon is a chemically
inert material, there is no chemical or corroding action with foodstuffs. The hard, glossy, non-porous surface of Plaskon
Molded Color does not of itself harbor fungi or germ life, and can be easily kept clean and sanitary.

Plaskon Molded Color does not readily or dangerously break or shatter. This
gives Hemcoware the important factors of safety and long life in heavy service.

Plaskon urea-formaldehyde and melamine-formaldehyde molding compounds are
easily and economically adaptable to the needs of industry and the individual.

FROZEN FOODS GET A "HOT" WRAP

No other packaging material can accomplish all
that Flax's polyethylene film does.

As the photograph shows, it is transparent and
will stretch to give a tight wrap for odd shapes,
like poultry. (The stretch is several hundred percent
without rupture.) At sub-zero temperatures, it re-
mains tough and pliable. It has excellent "feel." It
is non-toxic, odorless, tasteless and chemically inert.
It can be heat-sealed. The goodness of meats and
vegetables is fully protected but never hidden.

Plax polyethylene film comes in sheet form and in
plain or gusseted tubing. For the complete story

in Paris, France, Mr. Jacques Herrburger,
President and owner of Ets. J. Herrburger,
practically the sole large manufacturer of
piano mechanisms on the continent today.

We received a letter from him in which
he asked us to supply him with full data
on the suitable plastic materials for manu-
facturing of pianos, and on the method of
gluing them, recovering with felt, etc.,
as well as on the information relative to
the present use by other piano manufac-
turers. He also asks for samples and quo-
tations on this material. His question is
specific: "Can you receive material lor mold-
ing of parts, or parts already molded?"
Any information received with reference to
manufacturers will be appreciated.

Fred J. Kraft. President
Venango Plastics, Inc.
Franklin, Pa.

Gentlemen:

We have been looking around for a plas-
tic casting material. The Plastics Division of
The General Electric Company recommended
you as a source of information.

They stated that there is a casting ma-
terial on the market which consists of
Plaster of Paris extended and strengthened
with a plastics resin. Could you give us
the name of the company making this ma-
terial?

We want this material to use as a base
lor making art bouquets. It should go into
a mold in a semi hard state and remain
so, long enough for us to stick and ar-
range our material in an attractive man-
ner before hardening.

Any information you can give us will
be appreciated.

National Plastics Exposition

Ninety-nine representatives of mem-
ber companies of The Society of the
Plastics Industry, Inc., at a meeting
at Hotel Commodore, drew for
space in the Third National Plastics
Exposition. The exposition will be
held in Grand Central Palace,_ Sep-
tember 27 to October 1, inclusive
and will be larger and more com-
prehensive than either of its prede-
cessors.

Safety Record

A five-year comparison survey
completed by John L. Shear, safety
director of The Formica Insulation
Company, Cincinnati, manufac-
turers of laminated materials, shows
a marked improvement in the safe-
ty record of plant employees.

The plant safety record registered
an improvement of 38% in accident
frequency and a betterment of 55%
in the severity rate for the year
1947 compared to 1946.

Production Going On

The regular production of vinyl res-
in for fabricators and processors of
plastics is proceeding on schedule
at the new Painesville, Ohio, plant
of the Chemical Division of the
Glenn L. Martin Co.

Supplied as a white, granular
powder, this thermoplastic resin,
when mixed with other chemicals,
chiefly plasticizers, fillers, dyes sta-
bilizers and pigments, is spread or
calendered into sheets, films and
coatings to produce articles ranging
from crystal clear to opaque. Colors
cover everything from pure white
through vivid and pastel shades to
shiny black. According to formula-
tion, the material may be rigid or
elastic.

Commenting, Vice President Rob-
ert H. Kittner of the Chemicals Divi-
sion, points out "our production rec-
ords during the first few weeks of
operation have shown that our an-
nual output will be increased con-
siderably from that first estimated
and the Martin company now ex-

pects to contribute quite substan-
tially to the approximately two hun-
dred and thirty-five million pounds
of vinyl resin requirements which
the plastics industry predicts it will
utilize in 1948.

Flame-Retardant Research

Flame-retardant coatings for air-
craft fabrics are being sought
by several experimental groups.
Since' there are no fire-retardant,
film-forming materials which tau-
ten airplane fabrics as well as cel-
lulose derivatives, the research con-
sists of finding a coating which can
be applied over fabrics already
treated with' cellulose acetate bu-
tyrate dope.

Tests show that it is possible to
increase the interval between con-
tact with fire and destruction of the
fabric from 2 seconds with cellu-
lose nitrate dope and 6 seconds
with cellulose acetate butyrate
dope to 12 seconds with a fire-re-
tardant coating over the latter dope.

Wrinkle-Resistance

According to Dr. D. H. Powers of the
Monsanto Chemical Company, the
field of wrinkle-resistance finishes
has progressed to such an extent
that consumer markets will see
wrinkle-resistant garments this sum-
mer.

"Prior research had failed to pro-
duce crush-resistant cottons since
the resins then available gave ex-
cessive embrittlement and severe
loss of tear strength. Improved Res-
loom developments and greatly im-
proved mill application techniques
made possible the announcement
of Wrinkl-Shed cottons in 1947."

Cooperation Called For

Several problems have arisen con-
cerning the selling and promotion
of water-repellent garments. So
many industrial groups are working
to produce the finished garment
that cooperation among the many
industries has become necessary.
Consumers have complained that
so-called water-proof or water-repel-
lent garments just were not. The
consumers got wet.

Thus it would seem that coopera-
tion is called for among the chemi-
cal manufacturer, the finisher, the
owner of the fabric, the garment
manufacturer, and the retailer. The
duties of the chemical manufacturer

are summed up by Mr. Richard E.
Sumner of the American Cyanamid
Co. as follows: he "is responsible
for the quality of the finishing ma-
terial which he supplies."

"He should also supply to the
finisher all the technical information
he can as to the best methods of ap-
plying his product. After the finisher
has applied the finish to the fabric
in question, it must then be checked
and identified for the proper degree
of water repellency or spot repel-
lency as the case may be."

Plastic Insulation

Plastic foam insulating material,
that combines exceptionally low
thermal conductivity with very
light weight, is now being pro-
duced by United States Rubber Co.,
for low temperature installations.

Present applications include ship-
ping containers for fresh and frozen
foods, and commercial and home
refrigeration units. Other practical
uses are said to be transportation
refrigeration in trucks, railroad
cars, ships -and airplanes.

The snow white plastic foam is
available in shredded or block
form. The shredded form weighs
from .8 to one pound a cubic foot,
and the block form from .8 to 1.5
pounds a cubic foot.

The light weight and low thermal
conductivity are obtained through
the manufacturing process. Floto-
foam is made from a combination
of soluble resins, which are proc-
essed first into a liquid, then into
a froth, jelled, permanently set and
dried. Air bubbles, whipped in dur-
ing the frothing process, are per-
manently trapped, so the finished
material is over 99 per cent air and
less than 1 per cent solid. The ther-
mal conductivity or K value of the
shredded form is 0.173 to 0.208
BTU/hr/ftV'F./in. over a range
of mean temperatures from 9F. to
100F. The thermal conductivity of
the block form is from 0.20 to 0.23.

New Goodrich Process

A variety of fabrics made of yarn
covered with Koroseal film by a
recently developed process are now
available, according to the B. F.
Goodrich Company. Outstanding
qualities of these new fabrics con-
sist of porosity and excellent "hand"
or drape, as well as the fact that
they can be sewn or heat sealed,
with the sealing bond as firm as
that obtained on any Koroseal film.

AMERICA'S #1 SOURCE FOR PLASTIC CONTAINERS

It's a smart move to use

PLASTIC CONTAINERS

to step up sales, eliminate

breakage and cut transportation costs . .

Here's how plastic containers Celluplastic containers
increase sales: (1) by transparency, (2) by beauty of color
(transparent or opaque), (3) by beauty of design (pro-
duced in any design; any shape, long or short, round or
square, etc.).

In addition, Celluplastic containers (1) cut transporta-
tion costs (1/5 weight of glass), (2) eliminate breakage
(shatterproof), (3) conserve space (no bulky packing

needed). Permanent label imprinted during manufac-
ture. Seamless. Non-inflammable. Have consumer re-use
value.

Celluplastic is the world's largest producer of plastic
container. Est. 1919. Expert engineering staff. Blue-

otC ORATIVE USE

Farlite is made under great heat and pres-
sure, using base material of paper, fabric,
wood or Fiberglas impregnated with thermo-
setting resins. Very stable and durable. Re-
sistant to corrosion, moisture, and moderately
concentrated chemicals. Excellent machining
qualities. Maximum sheet size 36" x HI".

INDUSTRIAL SHEETS, including gear and
punching stork, used for electrical and me-
chanical parts. Can be accurately cut,
punched, machined, or drilled. Paper, fabric,
or Fiberglas base. Properties include high
dielectric strength, volume resistance, and low
moisture absorption. Stock with Fiberglas core
has great impact strength and arcing re-
sistance.

DECORATIVE SHEETS arc prefmishcd with
fade-proof solid colors or patterns, also genu-
ine wood veneers. The smooth, dense surface
withstands hard wear without chipping or
denting, and is not affected by alcohol, am-
monia, grease, fruit acids, salt water, or
cleaning solutions. Resists heat up to 275F.
Backs sanded for cold gluing. Used for veneer-

ing table tops, counter tops, panels, doors,
wainscot, stall partitions, etc. Also for dec-
orative trim in cabs, buses, coaches, elevators,
ships and planes.

POST FORMING STOCK has fabric base
and can be formed or drawn without fractur-
ing by heating flat sheets. Strong, light, and
economically processed. Shape remains per-
manent. Good electrical properties.

COMPREG is made of plies of hardwood
veneer, impregnated and compressed to about
one half original thickness. Very strong and
hard. Has high moisture and electric resis-
tance. Available in four grades. Hardest grade
requires machining with same tools as for
cast iron.

ENGRAVING STOCK has thin top layer with
thick sub-layer of contrasting color. Designs
or letters are engraved through surface ex-
posing sub-layer. Easily tooled. Surface will
not tarnish. For namcplates, tags, novelties,
etc.

problems. Many products and parts can be made far
more satisfactorily of plastic than of formerly-used
materials.

Many nationally-prominent manufacturers and as-
semblers have found our highly trained creative staff
of designers and engineers specialists in thermo-
plastics indispensable in analyzing and working out
their problems.

Moreover more prompt shipments of finished plastic
products are facilitated by our central location.

H-P-M all-hydraulic, compression molding presses
have proved their ability to meet spiralling produc-

semi-automatic production units double previous
speed standards with no additional
power requirements. Each press is
completely self-contained... totally
eliminating accumulators, lengthy,
pipe lines, two stage pressure sys-
tems. To the molder this means
reduced floor space requirements,
minimum maintenance expense...
great savings in power. H-P-M

assure undivided responsibility
plus long trouble-free service.

Ingenious New

Technical Methods

To Help You Simplify Production

Grommet Inserter

New Tool Inserts Rubber Grommets
Quickly . . . Easily!

A new tool called a Grommet
Inserter is shown above insert-
ing a rubber grommet in a Sub-
Chassis of a Zenith 7H820
Table Model Radio. The inset
illustrates a close up view of
the Grommet Inserter before
and after the grommet has
been inserted.

Anyone can insert grommets
in an instant with the new
Grommet Inserter. Saves time,
labor, and assures perfect fit.
No longer is it necessary to use
the time-consuming, cumber-
some method of insertion by
hand. The new Grommet
Inserter does it efficiently.
Simple as A-B-C. All you do
is push the Grommet Inserter
through the hole, open jaws,
place grommet in jaws, and
pull back leaving grommet
firmly in place, and perfectly
fitted. Comes in four standard
sizes: 14", 5/16", %", 7/16".
Can be furnished in any special
sizes to order.

You can count on chewing
gum, too, to help step up em-
ployee's on-the-job efficiency.
Chewing gum helps relieve ten-
sion and thereby enables him
to work quicker and easier
while leaving hands free.
That's why more and more
plant owners are making Wrig-
ley's Spearmint Gum available
to everyone.

glamorous new styling for
men who create business

These versatile, long wearing fabrics
add new color and practical luxury to...

automobile seat covers

The outstanding material among

fine auto seat covers, LUMITE -is

chosen for its wide variety of solid tones and

patterns ... its positive resistance to scuffing,

scarring and staining ... its ease of cleaning. The

LUMITE label appears on quality seat covers for

America's finest cars.

With warmth of color and
pleasant "hand," LUMITE gives
a smart, crisp note to furniture. Woven of Dow's
Saran and remarkably easy to handle, it lends
itself to fine tailoring. On garden or porch furni-
ture, LUMITE fabrics are unaffected by rain, sun
or snow, and will not mildew or rot.

transportation seating

On busses, trains, cars and

planes, LUMITE'S high resistance

to abrasion gives more wear per passenger mile.

Ink, gum, grease, candy, lipstick, or dirty feet

can't harm it. Cleaning is faster, simpler.

public places

Countless beautiful patterns

and lovely solid tones make

LUMITE fabrics especially adaptable to offices,

bars, restaurants, lounges and reception rooms.

Its crisp, non-cupping fit and ever-fresh color

insure that a public place decorated with LUMITE

stays new-looking longer.

Harmonizing beautifully with
any interior, sleek-tailored
LUMITE holds a snug, smooth fit on hard-used
seats in theatres, auditoriums and studios. It re-
quires less cleaning cleans far faster. Porous
weave circulates air, eliminates discomfort of
"sticking" to seat.

grilles for radios

LUMITE is "made-to-order" for

radio and speaker grilles where

its use results in high fidelity of ultra-low and

ultra-high tones. It will not sag or bulge and

is easily cleaned.

Write for free sample and information on LUMITE'S
adaptability to your individual requirements.
