Polyimide (PI)  Poly Benz Imidazol (PBI)
Superior endurance against heat, wearing, cracking and radioactive rays.  It still maintains excellent mechanical strength and creeping-resistant hardness when operating continuously at 310°C and presents a very low expansion coefficient when operating under temperature below 250°C. Further, it also presents excellent friction resistance, lower flammability, superior insulation and higher radiation resistance. 
Multi-layer base board, flexible base board, engine insulation wire. Copier machine split-claw, heat-disconnecting gear, missile radar antenna hood, heating roller bearing. Shaft jacket, push pin, shaft seal, valve seat.
