PEEK - Polyetheretherketone

Polyetheretherketone – PEEK, PAEK, PEKK

PEEK is a highly crystalline thermoplastic with excellent properties making it an ideal material for medical, electrical and electronic industries. Also makes great pump bodies, compressor components, valve seat, and housing applications.

Rated as “Best” or nearly the best in all mechanical properties of plastic materials. It carries UL 94-V-0 flammability rating and is FDA approved for food contact. PEEK has excellent dimensional stability, even under elevated temperatures.

VICTREX® is the leading supplier of this specialty resin with their Victrex® 450G material, although the name PEEK is the generic for the resin. This range of materials also includes: Avaspire®, PAEK and PEKK grades which offer similar property ranges; but have sightly different properties in either impact, heat or stress applications.

Medical Grade PEEK is USP Class VI certifiable, contact us for more information.

We Specialize in Engineering Plastics, Mechanical Plastics and PEEK High Performance Plastics

Why you should use PEEK:

  • It has excellent chemical resistance
  • has extremely high continuous temperature to 480 degrees F
  • Is outstanding wear resistance and low moisture absorption
  • Has good dimensional stability
  • Excellent Machining
  • Low co-efficient of friction/ Superior wear resistance
  • Dimensionally stable
  • Very low moisture resistance
  • Outstanding Wear resistance and excellent dimensional stability
  • Is USP Class VI approved for medical applications
  • This materials is…an excellent machining material – a favorite of machinists. Works like a soft brass, and has exceptional dimensional stability.
  • Excellent Machining
  • Victrex 450G PEEK Rod
  • Low co-efficient of Friction / Superior Wear Resistance
  • imensionally stable
  • Very low moisture resistance
  • Outstanding Wear Resistance and Excellent Dimensional Stability
  • Is USP Class VI approved – upon factory request (per batch)

Contact us for more information on all the other grades in the Ketone family. While it solves many demanding engineering requirements, it is also rather expensive. Most clients choose these resins as a last resort, but if your design calls for high heat, high chemical resistance, excellent dimensional stability, excellent wear resistance and/or USP certification, these are an excellent solution.

VICTREX has been at the forefront of high performance plastic materials, with PEEK being their flag-ship product line. Mil-P-46183 is most common specification associated with PEEK, call for additional information.
