Graphite Felts 2,000 °C

Graphite Felts, heat-resistant up to 2.000 °C

Rigid graphite felt comes from a natural mineral derivative of carbon (C). It has a hexagonally shaped structure and is soft and flexible. It is usually of black or grayish color. Carbon and graphite products are appreciated for their chemical and physical properties: chemically inert, thermal resistance, low thermal and electrical conductivity, low thermal expansion coefficient, low friction coefficient, low coefficient of absorption of X-rays and electrons. Moreover, these products can be used in different fields: they can be found in pencils and alkaline batteries but also in the metallurgy, automobile and high technologies industries.

Rigid graphite felt is available with a thickness of 40 mm (max. size 1,524 x 1,219 mm). This product is made of graphite fibres and a carbon binder. It is suitable for temperatures up to 2,200 °C. Specific widths and shapes can be cut. Other felts' options are also available.

     Benefits of High-Temperature Graphite Felts

  • Low thermal conductivity
  • Low specific heat: allowing for rapid heating and cooling of furnaces.
  • High thermal stability: in oxidizing atmospheres up to 350 °C, in protective or vacuum atmospheres up to approximately 3,000 °C for graphite and 1,000 °C for carbon.
  • Ease of processing: can be cut with scissors or blades. Adapted to small flexural radii.
  • Good surface properties: unaffected by all molten metals.
  • High purity: low sulphury and ash content
  • No electrostatic charging
  • High resistivity: coupling in an inductive field only occurs above 12 kHz.

     Main Applications of Graphite Felts

  • Thermal insulation of vacuum furnaces and inert gas
  • Degassing furnace
  • Brazing furnace
  • Annealing furnace
  • Sintering furnace for metals
  • Induction furnace
  • Filter for hot or corrosive liquids and gas and molten metal
  • Support for welding
