Clariant's 20% carbon fiber reinforced polyamide 6/66 (PA6/66-CF20) is created by combining an exceptional copolyamide 6/66 with long carbon fibers. This combination results in a material that is exceptionally strong, chemically and thermally resistant and has minimized warpage due to the carbon fibers.
  • Strong and tough engineering thermoplastic
  • Chemically resistant
  • High heat resistance
  • Long carbon fiber reinforcement helps minimize warping during printing and improves strength
  • Very high tensile strength
  • Reduced thermo-oxidative degradation
  • Minimized undesired yellowing due to ultraviolet light

  • Mechanical and technical application parts that require strength, toughness and thermal resistance
  • Prototypes
  • Tools, jigs, fixtures
  • ESD safe applications
*Subject to detailed product specifications.

Color Range
  • Black
  • Print Temperature = 240-260°C
  • Print Speed = 20-50 mm/s
  • Bed Adhesion = polyvinylpyrrolidone (PVP) based glue or a polyamide specific adhesion material applied to the build plate
  • Bed Temperature = ideally heated up to 80°C
  • Fan Settings = off to medium

Notes: parameters are dependent on printer used; Clariant tests were performed on an Ultimaker S5 printer.
