Product introduce
PPS (polyphenylene sulfide) products offer the broadest resistance to chemicals of any high performance plastic. They have no known solvents below 392°F and are inert to steam, strong bases, fuels and acids. Minimal moisture absorption and a very low coefficient of linear thermal expansion along with stress-relieving processes make these PPS products ideally suited for precise-tolerance machined components. In addition, PPS products exhibit excellent electrical characteristics and are inherently flame retardant. PPS is ideally suited for plastic components in automotive, electrical, appliance and industrial applications.
Polyphenylene sulfide (PPS) is an organic polymer consisting of aromatic rings linked with sulfides. Synthetic fiber and textiles derived from this polymer are known to resist chemical and thermal attack. PPS is used to make filter fabric for coal boilers, papermaking felts, electrical insulation, specialty membranes, gaskets, and packings. PPS is the precursor to a conducting polymer of the semi-flexible rod polymer family. The PPS, which is otherwise insulating, can be converted to the semiconducting form by oxidation or use of dopants
