PPS-GF40

Envalior · Xytron G4080HR

Polyphenylene sulfide with 40 percent glass fibre – a high-performance material combining high continuous temperature, chemical resistance and inherent flame retardancy. The hydrolysis stabilisation additionally makes it usable with hot water and steam.

These values are taken from the manufacturer datasheet and apply to the material, not to the printed part. In 3D printing the achievable properties depend on part orientation, layer height and process parameters – in the Z direction in particular they are lower. Please talk to us before relying on them for design.

“Qualified for functional parts” is a general classification. A functional part can be a simple clip or a main load-bearing member – the forces and load cases differ fundamentally. We therefore always assess in each individual case whether a material is suitable for your part.

Strengths

  • Very high continuous service temperature
  • Resistant to virtually all chemicals below 200 °C
  • Inherently flame retardant, without added flame retardants
  • Hydrolysis stabilised, therefore suitable for hot water and steam
  • Very good dimensional stability with low creep

Limitations

  • Brittle, with low impact strength
  • High processing temperature – demanding to process
  • The 40 percent glass content is strongly abrasive
  • Expensive material
