PEEK Machining

A Guide to PEEK CNC Machined Parts: Properties, Applications and Design Considerations

What is PEEK?

PEEK (Polyaryletheretherketone) is a rigid opaque (beige) engineering plastic known for its ability to operate at high temperatures, together with its exceptional chemical and wear resistance and dimensional stability.

A high purity polymer, PEEK is a plastic composed of repeating monomers of two ether groups and a ketone group.

Main Attributes of PEEK:

  • Impressive durability - exceptional chemical, electrical and temperature resistence
  • Excellent mechanical properties maintained to high temperatures
  • Dimensional stability
  • Very low moisture absorption
  • Flame retardant
  • High impact strength
