Concept Introduction 

PSFPPSIt is a new type of high-performance thermoplastic resin, featuring high mechanical strength, high-temperature resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties.

Primary Use 

Electronics: Television and computer high-voltage components, casings, outlets, terminals, motor starting coils, blades, brush holders, and rotor insulation parts, contact switches, relays, electric irons, hair dryers, lamp sockets, fan heaters.FGrade films, etc.

Automotive Industry: Suitable for exhaust recirculation valves and pump impellers, as well as carburetors, exhaust systems, exhaust regulators, light reflectors, bearings, sensor components, etc.

Mechanical Industry: Used for bearings, pumps, valves, pistons, precision gears, as well as parts for copiers, cameras, computers, conduits, sprayers, nozzles, and instruments.

Chemical Industry: Used for manufacturing acid and alkali-resistant valves, pipelines, fittings, gaskets, and corrosion-resistant parts such as submersible pumps or impellers.

Engineering Plastics: Used for manufacturing automotive parts, corrosion-resistant coatings, electrical insulation materials, etc.

Environmental Protection Field:PPSFiber filter media, suitable for industries such as smelting, chemical engineering, construction materials, thermal power generation, waste incinerators, and coal-fired boilers, under high-temperature and harsh working conditions, is an excellent and efficient high-temperature-resistant filter material.

Tableware field: Used for making chopsticks, spoons, bowls, plates, and other tableware.

Cautionary Notes 

Polysulfone, also known as Polyphenylene Sulfone, is a thermoplastic resin with a benzene sulfone group in its molecular backbone. Polysulfone is a crystalline polymer. The fiber, without stretching, has a larger amorphous region (crystallinity of about...5%)，in125℃Crystallization occurs with heat release, glass transition temperature is150℃Melting point281℃.Partial crystallization occurs in the stretching process of the elastic fibers, increasing to30%)，such as130-230℃Heat treatment of the stretched fibers at lower temperatures can increase the crystallinity.60-80%Therefore,PPSPlastic PowderThe fiber, after stretching, does not exhibit significant glass transition or crystallization exothermic phenomena; its melting point is284℃.As the crystallinity increases after stretching and heat setting, the density of the fiber also correspondingly increases, from that before stretching.1.33g/cm3After stretching1.34g/cm3After heat treatment1.38g/cm3Molding shrinkage rate:0.7% Molding Temperature:300-330℃。
