PPS

Polyphenylene Sulphide (PPS) is a high-temperature semicrystalline polymer that provides high thermal stability, very high chemical resistance, stiffness, strength and creep resistance. The Fortron 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.  PPS is inert to steam, compatible with common sterilization methods, and can be machined to tight tolerances.

Key Features

  • Excellent strength and rigidity up to 425°F continuous use with minimum decline in mechanical properties
  • High creep resistance even at elevated temperatures
  • Outstanding anti-fatigue and anti-creep properties
  • Superior chemical resistance
  • Excellent resistance to radiation, and inert to steam
  • Virtually no moisture absorption
  • Low coefficient of thermal expansion, high dimensional stability
  • Outstanding electrical properties at high frequency, high temp and high humidity
  • Inherently flame retardant (UL 94 V-0 rating)
  • Suitable for lead-free soldering

Typical Applications

  • Electrical/Electronic components
  • Manifolds
  • Chemical pump and motor parts
  • Gears, rotors and rings
