PEEK Injection Molding

PEEK parts offer high strength, stiffness, and chemical resistance


PEEK, or poly ether ketone, is a high performance thermoplastic with excellent strength and ductility. It's also FDA compliant for food contact and can be sterilized for medical applications.

Key benefits

  • Good strength and stiffness
  • High ductility
  • Chemically resistant
  • Food safe

PEEK Applications

Since PEEK is an inert material, it can be used in many applications that require chemical resistance. Industries such as medical, oil and gas, and aerospace often turn to PEEK for plastic parts.

PEEK is often used for the follow parts:

  • Bearings
  • Gears
  • Surgical instrumentation
  • Manifolds
  • Medical implants
