What is the PEI board? Characteristics and advantages of PEI board

Polyetherimide board is a kind of non crystalline plastic. Polyetherimide (pei) is a kind of high performance amorphous polymer extruded from engineering plastics by high temperature extruder.

It has good high temperature resistance, dimensional stability, chemical resistance, flame retardancy, electrical property, high strength and high stiffness. It has not only high mechanical efficiency, but also excellent heat resistance and chemical stability (continuous service temperature is about 170 ° c), as well as high dimensional stability and creep strength. It has high strength, high rigidity, wear resistance and high temperature dimensional stability. Without any additives, it has inherent flame retardancy and low smoke, oxygen index is 47%, and combustion grade is ul94-v-0. The density of polyethylene sheet is 1.28 ー 1.42 g/cm3, the glass transition temperature is 215 ° c, the thermal deformation temperature is 198 ー 208 ° c, which can be used for a long time at 160 ー 170 ° c, and the allowable intermittent use temperature of Z is 200 ° c. It has excellent mechanical strength, electrical insulation, radiation resistance, high and low temperature resistance, and fatigue resistance. It can add glass fiber, carbon fiber and other thermoplastic plastics to improve its unique torsional strength, As a cheap substitute for small steel cutting parts.
