Ultem® PEI Polyetherimide
Ultem® is an amorphous polyetherimide and is one of the most commonly used high-performance materials. It offers excellent thermal performance and high mechanical strength and stiffness. It is inherently flame retardant, possesses good resistance to acids and is capable of operating continuously in steam and hot water. Stock shapes from Ultem resin possess a combination of useful characteristics, including high strength at elevated temperatures (340°F continuous), high modulus, and broad chemical resistance. Ultem stock shapes are inherently flame resistant with low smoke emission. Ultem stock shapes display property retention and resistance to environmental stress cracking when exposed to a wide variety of chemicals.
The standard color of Ultem (unfilled) stock shapes is light amber. Glass-filled grades appear tan or greenish in color. Custom colors are available, minimums may apply.
Trade names for ULTEM
MCAM sells ULTEM under the name Duratron® U1000 PEI. Rochling sells UlTEM under the name SustaPEI
