PPS Plastic Material & Machining

Chemically resistant & mechanically strong material with excellent electrical properties

As a high performance thermoplastic, polyphenylene sulfide (PPS) stands as a popular choice for rings, rotors, bearings, and steam or water applications. With a semi-crystalline construction, this polymer consists of a long-chain aromatic structure with alternating sulfur atoms that contributed to its incredible chemical and thermal properties.

It is chemically resistant, mechanically strong, and dimensionally stable at temps up to 425°F. It also boasts near zero moisture absorption, and it machines to tight tolerances.
