The long-term creep resistance of polyetherimide under high temperature and stress allows it to replace metals and other materials in many structural devices. Shows good electrical performance under variable temperature, humidity and frequency conditions. The low loss factor at GHz makes polyetherimide highly microwave-permeable. Its low level of ionic pollutants, at 250F 100% H. After 120 hours of extraction with water at 207kPa and a conductivity of more than 20 megohms, it can be used as an insulating material for electronic sensor elements.
Polyetherimide is an excellent coating and film-forming material, which can form coatings and films suitable for the electronics industry, and can be used to make microporous membranes with a pore diameter of <0.1 μm and high permeability. Can also be used as high temperature resistant adhesives and high-strength fibers.
PEI board is a non-crystalline plastic. It is an amorphous high-performance polymer, which is made of engineering plastics made of amorphous PEI (polyetherimide) through an extruder at high temperature.
