Polyphenylene Sulfide (PPS)

Polyphenylene sulfide (PPS) is a high-performance engineering resin produced by the reaction of p-dichlorobenzene and sodium sulfide. The products a polymer, PPS, that offer high thermal stability, excellent chemical resistance, excellent electrical properties, high flow, and inherent flame resistance. Because of its low melt viscosity, PPS is commonly processed using injection molding, but grades are available for extrusion. Common applications include plumbing and water fittings, liners for downhole oil and gas pipes, technical fibers, film, electrical and electronic, healthcare, aircraft / aerospace and business machines.
