Polyphenylene sulfide (PPS) performance and applications of plastic profile
PPS all called poly phenyl sulfide, the main chain of molecular phenylthio with thermoplastic resin, the English called polyphenylenesnlfide (referred to as PPS). 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, wear, excellent creep resistance, excellent flame resistance. A self-extinguishing nature. Up to UL94V-0 grade, high temperature, high humidity despite good electrical properties. Good fluidity, easy molding, forming almost no shrinkage when the concave spot. With various inorganic fillers have a good affinity. === If enhanced after modification to improve their physical and mechanical mechanical properties and heat resistance (heat distortion temperature), glass fiber reinforced materials, carbon fiber, poly-aramid fiber, metal fiber, glass fiber-based. Inorganic fillers are talc, kaolin, calcium carbonate, silica, molybdenum disulfide. PPS / PTFE, PPS / PA, PPS / PPO and other alloys have been commercialized, PPS / PTFE alloy improved the brittleness of PPS, lubricity and corrosion resistance, PPS / PA alloy for high-toughness alloys. Glass fiber reinforced PPS has excellent thermal stability, wear resistance, creep resistance, in a wide range (temperature, humidity, frequency) has excellent mechanical and electrical properties of dielectric number of small, low dielectric loss. As a high temperature, corrosion coating, the coating can be long-term use at 180 ℃; electrical and electronic industry for connectors, insulating partitions, terminals, switches; machinery and machinery in to do the pump sticking close, gear, piston ring tank, leaves valves, watches parts, camera parts; auto industry on the carburetor. Distributor parts, electrical and electronic components group, etc., approved gas valve, the Department of Po-piece sensor; home parts have tape recorders structural components, chemicals body diode, the various components; the other one is also used in the aerospace, aviation industry, PPS / PTFE do anti-sticking, wear parts and transmission parts, such as the pump shaft.
