Graphite Foil


Graphite Foil is an excellent sealing material for high temperature, high-pressure transfer of liquids, gasses, steam, chemicals, and corrosives. The material is manufactured from high purity, high crystalline natural graphite flakes, which are processed into the continuous foil.

  • High purity material with excellent thermal stability and reflectivity.
  • Resistant to temperatures of 510℃ in air, 850℃ in steam, and 3000℃ in vacuum (or reducing).
  • Chemically inert with pH range of 0-14 (except strong oxidizers such as nitric or sulphuric acid).
  • Low coefficient of friction and self-lubricating.
  • Asbestos free and no associated health hazards.
  • Low electrical resistivity and high thermal conductivity.
  • Highly anisotropic. Electrical and thermal properties different parallel to and perpendicular to flakes.
  • Excellent in-process longevity – minimize replacement and down time costs.
  • Easy to cut and shape. Machine to print available for gaskets and seals.


  • Thermally conductive gasket, seal, or liner, while being heat and chemical resistant.
  • Release foils in glasswork and hot presses.
  • EMI (electromagnetic interference) and chemical shield.
  • Thermal management and heat dissipation liner.
  • Cathodes for electrolysis of liquids.
  • Dry sheet lubricant, stress sensing, vibration damping, spark plasma sintering (SPS) and other thermal electronic or electrochemical applications.
