PEEK
Polyetheretherketone
Continuous service temp.
to 250 °C
Replaces metal where mass and chemistry both matter.
Advantages
- Outstanding thermal stability and creep resistance
- Hydrolysis resistant, stable against aggressive media
- Excellent tribological and fatigue behaviour
Processing challenge
A 360–400 °C melt and an oil-heated tool at 170–200 °C. Requires a dedicated plasticising unit and tight scrap control — the material cost does not forgive rejects.
