PPS also known as: PPS is a crystalline (crystallinity 55% -65%) of white powder polymer with high stiffness, high heat resistance (continuous use temperature of 240 ℃), mechanical strength, stiffness, flame resistance, chemical resistance, electrical properties, dimensional stability are excellent resin, abrasion resistance, excellent creep resistance, excellent flame resistance. A self-extinguishing nature of UL94V-0 level. High temperature and humidity still maintained good electrical properties. Good fluidity, easy molding, molding, recessed spot almost no shrinkage. With various inorganic fillers have a good affinity. It was developed to shorten the standard thermoplastic materials (such as PA, POM, PET ... ...) and the difference between high-level engineering plastics. Features: air, the maximum allowable operating temperature is very high (ongoing work at 220OC, short up to 260OC), the high temperature environment to maintain a high mechanical strength, stiffness and hardness, excellent chemical resistance and hydrolysis resistance (currently not found to be below 200 ℃ solvent dissolved sulfide, inorganic acids, alkalis and salts of strong resistance), excellent wear and friction, very good dimensional stability, excellent resistance to high-energy radiation, good The UV resistance, its flame retardant, excellent electrical insulation. Applications: Electronics, Electrical: micro-electronic components packaging, coil skeleton, motor housings, relays, tuning capacitors and other components. Precision instruments: computers, timers, copiers, temperature sensors and a variety of measuring instruments and components shell. Mechanical: pump casing, pump impellers, valves, fans, flowmeter components, flanges, universal top. Automotive: ignition, clutch, transmission, gear boxes, bearing bracket, exhaust system components. Home
