PTFE Compounds

Non Melt

Melt

PTFE Compounds are composed of pigments and fillers such as glass, carbon, graphite and metal powders (bronze and molybdenum disulfide), other polymers and elastomers in varied proportions to achieve modified properties as per requirements . These molding powders offer enhanced wear resistance, creep resistance, thermal conductivity and electrical conductivity over virgin PTFE resins. Filled PTFE compounds also preserve several properties including low coefficient of friction, excellent chemical resistance and a wide service temperature range.

PTFE compound usage:

  • Large variety of seals and bushings
  • Bearings
  • Gaskets
  • V-rings/O-rings/Back-up rings
  • Hydraulic ring seals
  • Non-lubricated compressor rings
  • Valve seats and liners/swivel liners
  • Thrust washers
  • Lip seals
  • Standoff insulators
  • Feedthrough insulators
  • Wear pads
