PSU, PPS and other strong alternatives to PTFE

At Acoplastic we process all types of plastic materials into finished machine parts according to your wishes. In addition to PTFE and PEEK, we offer a wide range of high-tech plastic types, each with a unique set of advantages and features.

This includes:


PSU (Polysulfone) – an amorphous, transparent plastic, often used for transparency requirements – typically in the electronics, automotive, aerospace and domestic industries.

Mechanical Properties:

  • High mechanical strength and rigidity
  • Good hydrolysis resistance
  • Durable material, also at low temperatures
  • Resists radioactive radiation, gamma and x-rays
  • Can with benefit be used for food contact
  • Good electrical properties


PPS (Polyphenylene Sulphide) is a part-crystalline material, especially known for its good properties regarding fire and heat resistance. Used often for electrical components and when good chemical resistance is required. Additionally, by adding fillers, we can give PPS extra good stiffness.

Mechanical Properties:

  • High stiffness
  • Great hardness
  • Good dimensional stability
  • Good wear and friction properties
  • Notch sensitive

Choosing the correct PTFE compound or construction plastic for a given application is a complex task to, so drawing on Acoplastic’s insight and experience will save you both time and resources.
