Amber transparent solid, its pure resin has inherent flame retardancy and low smoke, oxygen index of 47%, burning grade of UL94-V-0, density of 1.28~1.42g/cm3, can be -160～180 Long-term use at °C operating temperature. PEI has strong high temperature stability, even for non-reinforced PEI, it has good toughness and strength, and PEI also has excellent mechanical properties, electrical insulation properties, radiation resistance, high and low temperature resistance, and wear resistance. Performance, flame retardancy, chemical resistance and low shrinkage with good isotropic mechanical properties, and through microwave, glass transition temperature is very high (215 ° C).
Glass fiber, carbon fiber or other fillers can be added to enhance the modification. It can also be combined with other engineering plastics to form a heat resistant polymer alloy. Excellent properties make PEI useful for making high temperature thermal devices.
Romiller can provide plastic sheets and rods with different properties such as carbon fiber, aramid fiber, PTFE, mineral, graphene, carbon nanotube, metal powder, glass fiber, glass microbead, molybdenum disulfide, stainless steel fiber, silicone oil, etc. material.

Due to its excellent balance performance, PEI can be applied to industrial sectors such as electronics, motors and aerospace, and as a substitute for metal for traditional products and cultural goods.
Fabrication of fiber optic connectors with PEI instead of metal allows for better component construction, simplifies manufacturing and assembly steps, and maintains more accurate dimensions.
Used in automotive applications such as high temperature connectors, high power lights and indicator lights, sensors that control the temperature outside the cabin (air conditioning temperature sensor) and sensors that control the temperature of the air and fuel mixture (effective combustion temperature sensor). It can also be used as a vacuum pump impeller for high temperature lubricating oil erosion, a ground glass joint (seat interface) for a steamer operated at 180 ° C, a mirror for non-illuminated anti-fog lamps, and the like.
