Ultem®
offers high heat resistance coupled with high strength, stiffness, UV
stability and broad chemical resistance. The combination of outstanding
thermal, mechanical and electrical properties together with exceptional
flame resistance and thermoformability, provide unprecedented
performance for a wide variety of demanding new design concepts.
The
following physical property information is based on typical values of
the base Ultem® 1000 resin as well as test results obtained from actual
film testing.

Ultem® with
Adhesive: CS Hyde can laminate Acrylic
Pressure Sensitive Adhesive to Ultem®; Adhesive laminations
available from .003" thick to .060" thick; .5" wide to 48"
wide. Ultem® Die-Cutting, Sheeting and Printing: CS Hyde can
die cut custom shapes, sheet custom lengths and
print Ultem® with barcoding, logos, etc.
Thermoforming:
DRYING--Ultem®
Film must be
thoroughly dried at 300°F before processing. Failure to do so
will result in bubbling of film. FORMING--Forming temps range
from 475F to 525F. Ultem® film rapidly cools so heating and
thermoforming units should be combined into one machine. Fast
forming cycles recommended.
Printing:
Parts fabricated from Ultem®
Film can easily be decorated by silkscreen & pad-transfer
printing. Flexography & offset printing may also be used but
are limited to simple shapes. Select inks based on printing
technique. Air-dry, plural-component & ultraviolet-radiation
curing inks are available
Outgassing:
Ultem® meets
stringent outgassing requirements. Clean room compatible.
