High Performance Forming Materials
Penn Fibre Plastics, Inc., an Ensinger
their new line of High Performance
Forming Materials at the
13th Annual SPE Thermoforming
Conference and Exhibition in
Cincinnati. This new lineup has been
developed specifically for the thermoforming
industry and will permit
processors a unique opportunity
to participate in growing global
markets that have previously
been unavailable to them.
New nylon offerings include both Pennite and DuPont™
Zytel® FS materials. Pennite nylons are available in type
6 and type 6/6 formulations with impact modifiers and
glass filled reinforcement. The nylons are heat ageing stabilized,
high viscosity materials with greatly improved
melt strengths. Pennite nylons have continuous service
temperatures of 140ºC (284ºF)
and peak operating temperatures
of 170ºC (338ºF).
color on these materials is black
for service applications. Custom
colors are available in production
The material is available in coils
from .010” to .093” thick and up
to 24” wide. Sheets are available
up to .250” thick, up to 48” wide.
Oversized sheets and metric sizes
are quoted on request.
The initial target market for Pennite nylons are for high
heat and under-the-hood applications. The first large
scale commercial product is being thermoformed by
Freetech Plastics, Inc. of Fremont, California utilizing
Pennite® 4508, a type 6 material with 15% glass filler.
Their product is an aftermarket air dam for Dinan
Corporation, the high performance BMW engineering
company of Morgan Hills, California. The air dam is
designed for BMW Series M3 automobiles. Pennite 4508
was selected for its mechanical and thermal properties,
ability to meet the BMW material specifications for 15%
glass filled nylons.
DuPont™ Delrin® Forming Solutions
DuPont Delrin Forming Solutions is the first and only
thermoformable acetal. Delrin® FS offers thermoformers
all of the great features that injection molders and fabrica-tors
have enjoyed for over four decades. The material is an
ideal choice for applications that require a high strength-to-
weight ratio coupled with exceptional scratch and wear
characteristics and superior dimensional stability. Delrin
FS provides a high level of resistance to solvents, fuels and
chemicals combined with a low moisture vapor transmis-sion
rate. The markets include those already served by
Delrin materials by other processes. These include medical,
consumer electronics, marine, automotive and bearing
and/or wear applications. These markets, which are
already very well served with Delrin acetal through injection
molders and fabricators, are very receptive to the
economies offered by thermoformers with Delrin FS.
An additional benefitis that it offers unique opportunities for topical decorating
previously unavailable with Delrin acetals. This material
may be painted, printed and enhanced with in mold decorating,
foil stamping and more. A wide range of options are available with DuPont Delrin Decorating Solutions.
Delrin FS is available in coils from .007” to .093” thick,
up to 24” wide. Sheet stock is available up to .250” thick
and up to 48” wide. As with Penn Fibre’s other products,
oversized and metric sizes are quoted on request. The nat-ural
color of Delrin FS is white and the material is available
in a wide array of stock and custom colors. Glass
filled and ESD formulations are also available on request.
Fortron PPS (polyphenylene sulfide) is available in numerous formulations for specific applications
including several that have been specifically formulated for
thermoformers. Fortron PPS resins are manufactured for
Penn Fibre by Ticona, a business unit of Celanese AG.
Ensinger is the global leader of PPS products in extruded
rods, plates and tubes as well as injection and compression
Fortron PPS has a wide list of exclusive features. It is inherently flameproof,
operates at temperatures in excess of 400°F and is vir-tually
unaffected by a broad range of chemicals even over
Some of the markets being served with Fortron PPS include semi conductors,
chemical tank lining, automotive, aerospace and electrical/electronic components. The introduction of this material
to thermoformers is sure to increase its list of applications.
The material is available from Ensinger/Penn Fibre in
coils from .010” to .062” thick and up to 24” wide. Sheets
are available up to .250” thick in widths to 48”. Stock
shapes, injection and compression molded products are
available through Ensinger Industries.
Additional Materials Include:
When Ensinger/Penn Fibre made their decision to enter
the thermoforming markets their goals and guidelines
were clearly established. “Bring forth new materials that
will add value and opportunity to new markets.” This new
line of High Performance Forming Materials certainly
shows their commitment to those ideals.
- DuPont™ Hytrel® (TPE) and their Surlyn® Reflection
Series offer numerous opportunities for formers in niche
applications for chemical resistance and extended
mechanical properties. Automotive opportunities are
prime applications for both materials.
Solef® PVDF is available with and without fiber backings
for forming chemical tanks and liners. PVDF provides
exceptional resistance to aggressive chemicals at elevated
- Ultem® is available in numerous grades including GE’s
new higher heat formulations. From food service through
medical and public transportation, Ultem® has always
been a favorite when high performance is required.
- Udel® Polysulfone exhibits exceptional hydrolytic and
dimensional stability with a high heat deflection temperature.
Polysulfone is a natural choice for fluid handling
and chemical resistance applications.
