Description

Reinforced engineering polymer (Polyetherimide) with 30% glass fiber. Amorphous thermoplastic polyetherimide (PEI) resins offers outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. They are available in transparent and opaque custom colors. These copolymers are available for even higher heat, chemical and elasticity needs.
