Polyphenylene sulfide (PPS)

PPS (Polyphenylene sulfide) is an organic polymer consisting of aromatic rings linked with sulphides. Synthetic fiber and textiles derived from this polymer are known to resist chemical and thermal attack at up to 240°C.  Rigid and opaque, PPS is used to make filter fabric for coal boilers, papermaking felts, electrical insulation, specialty membranes and gaskets.

More Information on PPS

  • History

    • 1888: PPS was uncovered by Friedel and Crafts
    • 1973: commercial process for polymerizing was successfully developed and manufactured by Phillips Petroleum (USA)

      Early versions of PPS had a relatively low molecular weight so applications were developed to use it in specialty coatings. However, once the molecular weight was increased by a thermal cross-linking reaction in the presence of oxygen, processing and mechanical properties were improved. Once it was discovered that PPS would be suitable for injection molding and had excellent heat and chemical resistance, demand increased, especially for more advanced engineering component applications.
