“CF” Data Sheet

Technical Data Sheet: Engineering Plastic Type “CF”

General Notes:
  • PA66/CF30 Polyamide 66 reinforced with 30 wt% carbon fiber heat stabilized
  • Very high rigidity, excellent tensile and flexural strength, fatigue and creep resistance.
  • Low friction, self lubricating properties, excellent wear and abrasion resistance.
  • Good heat capability.
  • Good chemical resistance (oils, grease, fuels, non polar solvents): not resistant to strong acids, alkalis and hot water or steam. For higher heat resistance and chemical compatibility see our “CP” PEEK Tweezers Line.
  • ESD Safe Material, very low surface resistivity.
  • Very low coefficient of linear thermal expansion.
  • Typical applications include handling and positioning of electronic components and devices, where an optimal balance between stiffness and surface smoothness is required.
