Graphite Felts 2,000 °C

Graphite Felts, heat-resistant up to 2.000 °C

Graphite is a mineral of elemental carbon (C) with a hexagonal crystalline structure. This flexible and soft material stands out with its black or grey-black colour. Carbon and graphite products are appreciated for their physical and chemical properties: heat resistance, chemical neutrality, electrical and thermal conductivity, low coefficient of friction, low absorption coefficient of X-rays and electrons as well as low coefficient of thermal expansion. Moreover, these products can be used in different fields: they can be found in alkaline batteries and pencils but also in the automobile, metallurgy and high technologies industries.

Graphite felts provied by Final Advanced Materials 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 thermal insulation of vacuum furnaces or the manufacture of different furnaces.

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

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

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
