sell Polyetherimide; PEI

Polyetherimide (PEI) is a super engineering plastic made of amorphous polyetherimide. It has the best high temperature resistance and dimensional stability, as well as chemical resistance, flame retardancy, electrical properties and high strength. High rigidity, etc., PEI resin can be widely used for high temperature terminals, IC bases, lighting equipment, FPCB (flexible circuit boards), liquid conveying equipment, aircraft internal parts, medical equipment and household appliances.
