PPS Guide: Properties, Applications and Design Considerations


What is PPS plastic?
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's a highly resistant polymer with high strength and hardness, especially in the higher temperatures. PPS plastic has good dimensional stability as well as low moisture absorption.

PPS is reasonably easy to machine. A high degree of precision can be obtained by using carbide tipped machine tools, moderate cutting speeds and fast feed rates. A slow feed can result in poor surface appearance.

If a large amount of machining is carried out, a second annealing procedure may be required to prevent cracking.

Industry Examples: Aerospace | Automotive | Medical | Chemical | Mechanical Engineering | Electrical & Electronics | Oil & Gas


Typical Components & Applications: Structural components | Valves | Filter housings | Pump/fitting components | Impellers | Roller bearings | Core formers | Connectors | Heat shields | Surgical instrument components | Gears | Chain guides | Bushings | Nozzels | Rollers

Main Attributes:
  • 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

Note For Designers:

40% glass reinforced PPS is probably the most widely used grade although PPS itself is not as widely used in the UK as a number of other engineering plastics such as PEEK.

If the extremely high chemical resistance of PPS is not required, alternative cheaper and more readily available thermoplastics may be sought.
