Graphite Foil By The Foot


Graphite Foil by the roll (Grafoil) are cut from our production rolls and stocked. The sheets are an excellent sealing material for high temperature, high-pressure transfer of liquids, gasses, steam, chemicals, and corrosives. Foil is manufactured from high purity, high crystalline natural graphite flakes, which are processed into the continuous foil.

Shipping Information

Foil is shipped through a combination of UPS and freight depending on the order to ensure safe delivery. Additional cutting/crating cost of $45 for Foil by the foot. Please contact us directly for a custom shipping quote or place your order and a CeraMaterials’ representative will contact you to confirm shipping cost before processing your order.

Product Documentation


  • 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.
