(polyetherimide)
|
Download Product Brochure (43kb - pdf)
|
An amorphous thermoplastic polyetherimide, stock shapes from ULTEM® resin possess a
combination of useful characteristics, including high strength at elevated temperatures, high
modulus, and broad chemical resistance. Tempalux stock shapes are inherently flame resistant
with low smoke emission. Tempalux stock shapes display property retention and resistance to
environmental stress cracking when exposed to a wide variety of chemicals. Glass filled grades appear tan or greenish in color.
Tempalux rod, slab, and tubular bar are air annealed for stress relief.
The following physical property information is based on typical values of the base polyetherimide
resin (PEI).
