3MTM DyneonTM Modified PTFE Compound TFX 4262 is a free-flowing suspension PTFE compound containing 10 % carbon fibre for compression and automatic moulding.

Special Features are:

  • Increased thermal dimensional stability
  • Increased surface hardness
  • Improved deformation under load
  • Reduced friction & wear
  • Good chemical stability
  • High limiting oxygen index (LOI)
  • Low friction behaviour
  • Very good mechanical properties
  • Exceptional temperature resistance

  • Typical Properties:

    PTFE compound moulding powder with very small particle size is preferred for moulded parts requiring very good mechanical properties.
