PPS plastic (polyphenylene sulfide) is a thermoplastic special engineering plastic with excellent comprehensive properties. Its outstanding features are high temperature resistance, corrosion resistance and superior mechanical properties. PPS is a white, high crystallinity, hard and brittle polymer. The relative density of pure PPS is 1.3, but it will increase after modification. PPS has a very small water absorption rate, generally only about 0.03%. PPS has good flame retardancy, and its oxygen index is as high as 44% or more; compared with other plastics, it is a high flame-retardant material in plastics.
The application of PPS is centered on its excellent heat resistance, taking into account its anti-friction self-lubricating properties, chemical stability, dimensional stability, flame retardancy and electrical insulation, etc. In the chemical industry, PPS can be used as reaction tanks, pipelines, valves, chemical pumps, etc. for synthesis, transportation, and storage of materials. In the mechanical center, PPS can be used to make impellers, blades, gears, eccentric wheels, bearings, clutches, and wear-resistant parts; The main use is still in the field of electronic appliances, such as making transformer skeletons, high-frequency coil skeletons, plugs, sockets, wiring frames, contactor drums and various precision parts.
In the automotive field, PPS is mainly used for automotive functional parts, which can replace metal-made exhaust cylinder circulation valves and water pump impellers, pneumatic signal regulators, temperature sensors, carburetors, evolutions, carburetor pumps, seat bases, water tank chambers, ignition Inverters, heaters, light reflectors, lamp holders, bearings, oil pan screws, automotive alternator regulators, coil bobbins and brackets, etc.
