Download Product Brochure (22kb - pdf)
|
An amorphous thermoplastic polyetherimide, stock shapes from ULTEM® resin
possess a combination of useful characteristics, including high heat resistance,
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.
The following physical property information is based on typical values of the base
polyetherimide resin (PEI).
