Product Features

The density is 1.45, the glass transition temperature is 215 °C, and the heat distortion temperature is 198~208 °C. It can be used for a long time at 160~170 °C, and the maximum allowable intermittent use temperature is 200 °C.

It has the best high temperature resistance and dimensional stability, as well as chemical resistance, flame retardant, electrical properties, high strength, high rigidity, etc.

Not only has high mechanical performance, but also has excellent thermal and chemical stability (continuous use temperature of about 170 ℃), as well as high dimensional stability and creep strength. It has high strength, high rigidity, wear resistance and dimensional stability at high temperature.

Without adding any additives, it has inherent flame retardancy and low smoke, the oxygen index is 47%, and the combustion grade is UL94-V-0.

Main application

PEI board has excellent comprehensive balance performance, and is effectively used in electronics, automobiles, motors, aviation and other industrial sectors, and is used as a metal substitute for traditional products and cultural daily necessities.

Commonly used in microtools/catering, analytical instruments, medical equipment, telecommunications, molded interconnects (MTDs), automotive lighting, aircraft interiors, HVAC/fluid handling, etc.

PEI has excellent hydrolysis resistance, so it is used as handles, trays, jigs, prosthetics, medical lamp reflectors and dental appliances for medical surgical instruments.

PEI has excellent mechanical strength, electrical insulation properties, radiation resistance, high and low temperature resistance and fatigue resistance and molding processability;

adding glass fiber, carbon fiber or other fillers can achieve the purpose of reinforcement and modification. Torsional strength, making it an inexpensive alternative to small steel cut parts.
