High Temperature Carbon and Graphite Felts 2000°C

Soft Carbon and Graphite Felts

Carbon and Graphite Felts, up to 2,000 °C

Graphite is 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.

Benefits of Carbon and 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.

Carbon and Graphite Soft Felts, up to 2,000 °C

Carbon and graphite felts with thicknesses of 6 and 11 mm with a width of 1,200 and 1,270 mm are available. Specific widths can be provided and special shapes can be cut to your specifications.

Applications of Carbon and Graphite Soft Felts

  • Thermal insulation for vacuum furnaces and inert gas furnaces
  • Heated smelting and holding furnaces
  • Inductively heated furnaces
  • Filters for hot and/or corrosive gases and liquids, for molten metals
  • Backing strips for soldering and welding
