Polyether ether ketone (PEEK) is a colourless, organic, crystalline thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications.  PEEK™ offers excellent thermal and chemical resistant properties and outstanding resistance to abrasion and dynamic fatigue.  It is recommended for electrical components where a combination of high continuous service temperature (480°F) with very low emission of smoke and toxic fumes on exposure to flame is required.  Some trade names for PEEK™ include Ketron®, Victrex®, SustaPEEK and TECAPEEK®.

CCT Precision Machining is an industry leader in PEEK™ Machining.  We are able to maintain tolerances, create features and produce parts that even the material manufacturers deem impossible. By using high speed spindles capable of turning at 30,000 RPM, tightly controlled work envelopes and cutting edge work holding systems, CCT Precision can machine thermoplastic components from the most simple part to the most intricate part on any of the 25+ machines in our facility.

  • MIL P 46183
  • 27” x 15” x 13” Work Envelope
  • Tolerances to +/- .00025” (0.006 mm)
  • Hole Diameters to 0.003” (0.076 mm)
