Overview
Polyetherimide (PEI) is a high performance engineering thermoplastic. PEI’s characteristics include high strength and rigidity at elevated temperatures, long term heat resistance, dimensional stability and good electrical properties.
Like other amorphous, high temperature resins, PEI has outstanding dimensional stability and is inherently flame retardant. PEI does resist chemicals, such as hydrocarbons, alcohols and halogenated solvents.
Creep resistance over the long term allows PEI to replace metal and other materials in many structural applications. Electrical properties show excellent stability under variable temperature, humidity and frequency conditions.
