PPS(Polyphenylene sulfide)

  PPS (Polyphenylene sulfide), the molecular structure of PPS is comparatively simple, and the main molecular chain is alternately arrayed by benzene ringsand sulfuratoms, lots of ringsand 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.

Imported German Radiation resistance pps sheet

PPS is a semi-crystalline high performance thermoplastic with optimised tribological properties for demanding bearing and friction requirements.Its main characteristics are:

• Very good sliding properties even without lubrication
• Good thermal mechanical bearing strength
• Good chemical and hydrolysis resistance even against superheated steam
• Very wear resistant
• Very rigid
• Creep resistant
• Not electrically insulating
• Good machinability
• Resistant to gamma radiation
• Self extinguishing V-0

The preferred fields of use for PPS are; Mechanical and automotive engineering, nuclear and vacuum technology, transport and conveyor technology, pump technology, textile, packaging and paper processing machinery, precision and chemical engineering, plant construction, aircraft and aerospace industry.
