PPS Machined Parts

A Guide to PPS CNC Milled & Turned Parts: Properties, Applications and Design Considerations

What is PPS?

Polyphenylene sulphide (PPS) is a semi-crytalline, high temperature thermoplastic polymer. PPS offers the broadest resistance to chemicals of any advanced engineering plastic.

Because of PPS's chemical structure it is a highly resistant polymer with high strength and hardness, especially in the higher temperatures. PPS has good dimensional stability as well as low moisture absorption.

Main Attributes of PPS:

  • High chemical resistance
  • High temperature performance
  • High modulus when reinforced 
  • Good mechanical strength
  • Low water absorption
  • Good dimensional stability
  • Excellent electrical properties
  • High purity characteristics
  • High maximum allowable temperature in air (220°C continuously, 260°C in bursts)
  • Suitable for food contact
