Polysulfone, abbreviated as PPS, is a new type of high-performance thermoplastic resin.High mechanical strength, heat resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties.It is a high-performance thermoplastic specialty engineering plastic with outstanding features such as high-temperature resistance, corrosion resistance, and superior mechanical properties.Widely used in the fields of electronics, automotive, machinery, and chemicals.PPS is used in the electronics and electrical industry, accounting for 30%, suitable for high-temperature electrical components with operating temperatures above 200℃; it can be used to manufacture points, electrical supports, starter coils, shields, and blades for generators and engines; on televisions, it can be used for high-voltage enclosures and sockets, terminals, and terminal boards; in the electronics industry, it is used for transformer, inductor, and relay frames and casings, as well as integrated circuit carriers; it is also used to produce H-level winding supports and trim capacitors due to its high-frequency performance. It is also applied to microelectronic components, connectors, terminals, sockets, coil frames, motor casings, electromagnetic adjustment disks, television high-frequency heads, relays, trim capacitors, fuse holders, tape recorders, magnetic therapy devices, and other components. It is also used in precision instruments: computers, timers, tachometers, copiers, cameras, temperature sensors, and casings and components for various measuring instruments.
