What accessories does PPS engineering plastics use on the car?
Polyphenylene sulfide (or poly phenylene sulfide)[PPS] is a crystalline polymer, which is the lowest price in high temperature engineering plastics and can be molded by thermoplastic processing method. Its typical product is called "Ryton" (Phillips products).PPS 55%-65% is a high degree of crystallinity, rigid white powder polymer, high heat resistance, mechanical strength, rigidity, flame resistance, chemical resistance, dimensional stability, resin has excellent electrical properties, abrasion resistance, creep resistance and excellent flame retardancy. Self extinguishing. Up to UL94V-0, good electrical performance is maintained under high temperature and high humidity. Good liquidity, easy to shape, almost no shrinkage hole when forming. It has good affinity with various inorganic fillers. Enhanced after modification can improve the physical and mechanical = if the mechanical properties and heat resistance (heat distortion temperature), reinforced with glass fiber, carbon fiber, aramid fiber, metal fiber, glass fiber. Inorganic filling materials are talc, kaolin, calcium carbonate, silica, molybdenum disulfide and so on.
PPS/PTFE, PPS/PA, PPS/PPO and other alloys have been commercialized. PPS/PTFE alloy has improved the brittleness, lubricity and corrosion resistance of PPS. PPS/PA alloy is a high toughness alloy.Excellent heat resistance: its melting point is more than 280 degrees, the thermal deformation temperature is more than 260 degrees centigrade, and the long-term use temperature is 220-240 degrees centigrade. The degradation rate of the inert gas is 1000 at 700 DEG C in the air, and the weight of the inert gas remains 40%. The thermal stability of the short term heat resistance and long-term continuous use is superior to all the existing engineering plastics. The temperature of hot deformation can reach above 350 degrees after specially modified varieties.Its flame retardant: polyphenylene sulfide flame retardant can reach UL94-0, oxygen index (LOI) >57%. Polyphenylene sulfide has its own chemical structure, so it has good combustion resistance, without adding flame retardant.
