PPS Compounds

Material overview

Polyphenylene sulfide is a high-performance engineering thermoplastic with excellent heat and chemical resistance, high stiffness, low moisture absorption and strong dimensional stability. Reinforced PPS compounds are well suited to demanding automotive, electrical and electronic, industrial and aerospace applications.

Key properties

  • Long-term thermal performance for high-temperature environments.
  • Excellent resistance to acids, alkalis, solvents and many industrial chemicals.
  • High strength and stiffness with good property retention at elevated temperature.
  • Good wear performance and low friction for selected sliding components.
  • Low moisture absorption and low thermal expansion for dimensional stability.
  • Inherent flame retardancy and good electrical insulation.
  • Suitable for precision injection molding and extrusion with appropriate processing conditions.

Typical applications

  • Automotive under-hood and electrification components
  • Electrical insulation and connectors
  • Pumps, valves and industrial components
  • Precision components
