Polyphenylene Sulphide, PPS
Polyphenylene Sulphide plastics have exceptional heat, chemical and flame resistance.
Their high heat resistance combined with good electrical insulation properties means PPS plastics have found use in electrical components in place of metals and some thermosets. Polyphenylene Sulphide is able to produce a surface finish that can accept vapour metallization without the need for intermediate painting.
Applications include cooking appliances, sterilisable laboratory equipment, hairdryer grills, automotive components including exhaust gas return valves, carburettor components, and ignition plates.
Polyphenylene Sulphide plastics are rigid, opaque non-burning, and have continuous capabilities up to 250’C. They have good chemical resistance, and are a good electrical insular. They are moisture resistant, and are rarely used unfilled.
Polyphenylene Sulphide plastics have good tensile strength and flexural modulus together with good electrical properties. Glass fibre filled PPS gives good heat distortion whereas carbon fibre filled PPS does this even better with dimensional stability and rigidity. PPS, when PTFE lubricated, will give good wear and low coefficient of friction.
Polyphenylene Sulphide can easily be processed by Injection Moulding, and ProPlastix can advise on all your specific applications.
