Polyphenylene Sulfide (PPS)

All Resin Families

Polyphenylene Sulfide (PPS) is a high-temperature semicrystalline polymer that provides high thermal stability, very high chemical resistance, stiffness, strength and creep resistance.

Polymer Characteristics

  • High strength and stiffness
  • High HDT (260°C / 500°F)
  • Long term CUT 200°C / 392°F
  • Excellent chemical resistance
  • Good electrical properties
  • Excellent dimensional stability
  • Inherently self-extinguishing (UL 94 V0)

The PPS chemical structure provides excellent chemical and thermal resistance. Insoluble in all known solvents below 200°C (392°F), it has very good stability in both typical and alternative automotive fuels.


  • Glass-filled grades
  • Mineral-glass grades
  • Low-wear grades
  • Blow-molding grades
  • Medical grades

Processing Methods

  • Injection molding
  • Extrusion (film, fiber, sheet, shapes)
  • Blow molding

Unfilled, high viscosity Fortron PPS is also suitable for extrusion and compression molding to produce sheets, rods and other stock shapes commonly used for prototyping.

Typical Applications

  • Bobbins, contact holders, lamp parts, brush holders, shields, connectors
  • Pump housings and impellers
  • Fuel injection and exhaust components
  • Washers and bearings

It has broad automotive, drinking water, food contact and aerospace approvals.
