High Temperature Graphite Felts 2,000 °C

Graphite Felts, up to 2,000 °C

Graphite is a mineral of elemental carbon (C) with a hexagonal crystalline structure. This soft and flexible material stands out with its black or grey-black colour. Carbon and graphite products are appreciated for their chemical and physical properties: chemical neutrality, heat resistance, thermal and electrical conductivity, low coefficient of thermal expansion, low coefficient of friction as well as low absorption coefficient 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.

Graphite felts offer excellent thermal resistivity. They can indeed withstand operating temperatures up to 2,000 °C in inert atmosphere. These products are mainly used in the industry for the manufacture of different furnaces or the thermal insulation of vacuum furnaces.

Final Advanced Materials proposes flexible and rigid graphite felts with a thickess ranging from 6 to 50 mm. A purified version of these graphite felts is available, with a proportion of ash lower than 20 ppm.

For more information regarding the availability, refer to the technical data sheet.

Benefits of 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.

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
