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. The standard color of
Tempalux stock shapes is light amber. 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). |
