Ketron® Peek


The Ketron® PEEK group of materials is based on polyetheretherketone resin. This advanced material exhibits a unique combination of high mechanical properties, temperature resistance and excellent chemical resistance and is an extremely useful, popular and accessible advanced plastics material.

Ketron® PEEK grades offer chemical and hydrolysis resistance similar to PPS, but can operate at higher temperatures.
PEEK 1000 offers steam and wear resistance, while carbon-reinforced PEEK provides excellent wear capabilities. Our latest grade, PEEK HPV, offers outstanding bearing performance. PEEK can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties.

For hostile environments, PEEK is a high strength alternative to fluoropolymers.

PEEK carries a V-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.

Main properties of our range of PEEK sheet and rod are:

  • Very high maximum allowable service temperature in air (250°C continuously, up to 310°C for short periods)
  • Excellent chemical and hydrolysis resistance
  • Very low moisture absorption
  • Inherently good wear and abrasion resistance
  • Very good dimensional stability
  • Excellent resistance to high energy radiation (gamma- and X-rays)
  • Unaffected by continuous exposure to hot water or steam
