Self extinguishing HPV PPS tube TECHTRON PPS pipe
PPS(Polyphenylene sulfide)
1.Description:
PPS(Polyphenylene sulfide) is a semi-crystalline high performance thermoplastic with optimised tribological properties for demanding bearing and friction requirements. The molecular structure of PPS is comparatively simple, and the main molecular chain is alternately arrayed by benzene rings and sulfuratoms, lots of rings and sulfur and sulfuratoms supplies PPS with the rigidity resistance as well as the pliancy resistance. The inner symmetrical molecular structure makes PPS easily crystal, non-polarity, good electrical resistance and low water absorption and so on. Guangzhou Engineering Plastics Industries (Group) Company has studied and applied this material in many industries for many years.
