Polyetherimide

● Continuous service in air for up to 20,000 hours, with a maximum allowable working temperature of 170°C

● High mechanical strength, rigidity, hardness, and creep resistance at both room and elevated temperatures

● Physiologically inert (FDA-compliant, suitable for food contact)

● Semi-translucent (not fully transparent for visible light applications)

● Exceptional hydrolysis resistance (suitable for steam sterilization)

● Good dimensional stability

● Excellent electrical insulation and thermal insulation properties

● Superior resistance to high-energy radiation

✔ Standard & Anti-Static Grades:

PEI 1000 (Ultem® 1000) – Virgin PEI resin, high purity, excellent thermal & mechanical performance

PEI 2300 (Ultem® 2300) – Glass-fiber reinforced for enhanced strength, stiffness, and dimensional stability
