Description Polyetherimide (PEI) is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK.

Application This high strength material offers excellent chemical resistance and ductile properties suitable for various applications, even those including steam exposure.

Features And Benefits Relative to PEEK, PEI is cheaper, but is lower in impact strength and usable temperature.
The glass transition temperature of PEI is 217 °C (422 °F). Its amorphous density at 25 °C is 1.27 g/cm3(.046 lb/in³). It is prone to stress cracking in chlorinated solvents. Polyetherimide is able to resist high temperatures with stable electrical properties over a wide range of frequencies.
