“CP” Data Sheet

Technical Data Sheet: Engineering Plastic Type “CP”

General Notes:

  • PEEK/CF 30 Polyetheretherketone reinforced with 30 wt% carbon fiber
  • Very hard, rigid, high tensile and flexural strength
  • Very high wear resistance
  • High heat capability (260°C – 300°C)
  • Good dimension stability
  • Low thermal linear expansion coefficient
  • Excellent resistance to chemicals and aggressive agents, excellent resistance to thermal aging.
  • ESD Safe Material, low surface resistivity (105ohms)
  • Typical applications include handling of components in cleaning/chemical/assembly processes also at high temperature (soldering)

This material is used in our “CP” Peek Replaceable Tip Tweezers, Wafer Handling Tweezers and Probes.
