Introduction to Polyetherimide (PEI)

PEI provides a high degree of creep resistance, weather stability, chemical resistance, Stiffness, stress cracking resistance, Dimensional stability, and fair electrical conductivity.

Because of these flexible properties, It is suitable for fabricating voltage breakers &carburetor housings, microwave housing, medical and chemical instruments, aerospace parts, and many more.
