PEI

Polyetherimide (PEI) is a high-performance engineering thermoplastic known for its excellent combination of thermal stability, mechanical strength, stiffness, dimensional stability, and electrical performance. It maintains its properties at elevated temperatures and offers good resistance to many chemicals, wear, and hydrolysis, making it suitable for demanding environments. PEI also provides inherently good flame resistance and low smoke characteristics in suitable grades, supporting its use in applications where stringent safety requirements are important. It can be processed through injection molding and other conventional thermoplastic manufacturing techniques, while glass-fiber reinforced grades are available for increased strength and stiffness. PEI is widely used in aerospace components, automotive parts, electrical and electronic housings, connectors, medical equipment, laboratory components, industrial machinery, and other high-performance applications.
