Ketron PEEK MD, the new PEEK metal detectable material, is best suited for applications where high line speeds require good wear resistance, or where operating temperatures in use are higher than 130 °C.

Ketron PEEK grades offer chemical and hydrolysis resistance similar to PPS but can operate at higher temperatures. Unreinforced, extruded Ketron PEEK MD offers good wear resistance and can be used continuously to 480°F (250°C). It can also be used in hot water or steam without permanent loss in physical properties.


  • Good material solution for machine parts which undergo multiple sterilization, mainly in equipment with CIP (cleaning in place) and SIP (sterilization in place)
  • Suitable for food approved parts requiring high stiffness without reinforcement
  • High dimensional stability for high precision parts
  • Good impact / stiffness ratio
  • Excellent chemical resistance


  • Filling Pistons
  • Manifolds and valves
  • Scrapers in cookers
  • Thrust washers
  • Guiders
  • Bushings
