PPS is a high rigidity white powder polymer of crystalline type (crystallinity 55%-65%), high heat resistance (continuous use temperature of 240°C), mechanical strength, rigidity, flame resistance, chemical resistance, electrical characteristics Excellent dimensional stability, excellent wear resistance, excellent creep resistance, excellent flame retardancy. Self-extinguishing. Up to UL94V-0 grade, still maintain good electrical performance under high temperature and high humidity. Good fluidity, easy molding, almost no craters when forming. With a variety of inorganic fillers have a good affinity. After the modification is modified, === If the physical and mechanical mechanical properties and the heat resistance (heat distortion temperature) are improved, the reinforcing material includes glass fiber, carbon fiber, aramid fiber, metal fiber, and the like, and the glass fiber is dominant. Inorganic fillers include talc, kaolin, calcium carbonate, silica, and molybdenum disulfide.
Alloys such as PPS/PTFE, PPS/PA and PPS/PPO have been commercialized. PPS/PTFE alloys have improved the brittleness, lubricity and corrosion resistance of PPS. PPS/PA alloys are highly ductile alloys.
Glass fiber reinforced PPS has excellent thermal stability, abrasion resistance, creep resistance, excellent mechanical and electrical properties over a wide range (temperature, humidity, frequency), low dielectric constant, dielectric loss low. As a high-temperature, anti-corrosion coating, the coating can be used at 180°C for a long period of time; connectors, insulation separators, terminals, and switches are used in the electrical and electronic industry; pumps and gears, piston ring storage tanks, and blades are used for mechanical and viscous machinery. Valve parts, clock parts, camera parts; automotive parts such as carburetor, distributor parts, electrical and electronic components, batch valve gas, and sensor parts; appliance parts including tape recorders, parts, body diodes, and various Parts; the other is also used in aerospace and aviation industries, PPS/PTFE can do anti-stick, wear parts and transmission parts, such as shaft pumps.
