SUSTAPEI (ULTEMTM 1000) 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. SUSTAPEI (ULTEMTM 1000) is offered in Natural (amber transparent) and Black.

Ultem® 2200 is a polyetherimide is an amber (20%) glass filled high performance polymer which combines high strength and rigidty at elevated temperatures with long term heat resistance.

SUSTAPEI GF 30 (ULTEMTM 2300) is 30% glass reinforced and provides enhanced stiffness, strength and dimensional stability for more demanding applications.
