Chambroad Petrochemicals PPS-ET High Strength, Polyphenylene sulfide
Categories:	Polymer; Thermoplastic; Polyphenylene Sulfide (PPS)
Material Notes:	Modified PPS Materials: Polyphenylene sulfide (PPS) resin has a simple molecular structure and is a heat-resistant crystal polymer of the unit consisting of an aromatic ring alternated with sulfur atoms. With a melting point of about 280°C, the resin has a high resistance to heat and reagents, and can extinguish automatically without adding flame retardants. Since PPS can replace metal or thermosetting resin, it is widely applied in the fields of car parts, electrical/electronic parts, housing facilities, OA, and precision equipment. Application Field: Aerospace - Gun shells, helmets, corrosion-resistant and wear-resistant parts of warships and submarines, aircraft connectors, coil frames, and instrument panels.
