polyetherimide

Download Datasheet (pdf 43kb)

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).

Tempalux® - glass filled

Applications Include:
Burn-in test sockets
Connectors
Automotive components
"Valves, electrical fittings"

Advantages of Tempalux® - glass filled
Inherent flame resistance
Extremely low NBS smoke evolution
Superior limiting oxygen index
Exceptional tensile and flexural strength
Broad chemical resistance
UV stable
FDA compliant

Manufacturing Capabilities:
Rod: 1/4" to 8" diameter
Sheet: .035" to 1/4" thick
Slab: 3/8" to 4" thick

Color/Grades:
Tan/Green
(custom colors available)

*In addition to our standard capabilities, Westlake also has the ability to process custom resins in various sizes and colors with some exceptions.
