Product Name:Polyetherimide
English Name:Polyetherimide
CAS No.:61128-46-9
Aliases:PEI, Polyetherimide resin
Molecular Formula:(C37H24N2O6)n
Physical Properties:Amber to transparent amorphous thermoplastic resin with a density of approximately 1.27–1.30 g/cm³. Glass transition temperature ~217°C, heat deflection temperature (1.82 MPa) ~200°C, and long-term continuous service temperature ~170°C. It features excellent heat resistance, high mechanical strength, dimensional stability, flame retardancy, and electrical insulation; resistant to most chemicals but sensitive to strong acids, strong bases, and some halogenated solvents.
Uses:Injection molding grade polyetherimide, suitable for standard injection molding processing. Widely used in automotive, electrical/electronic, aerospace, and medical device industries to manufacture connectors, switches, relays, motor components, and other high-temperature structural parts.
