PAN-based Carbon Felt

Short Description:

Polyacrylonitrile (PAN) based carbon felt is light in quality, small in specific heat capacity,soft in texture, good in adiathermancy and convenient in operation, which can save great energy. Therefore, thermal insulation of the polyacrylonitrile base is extremely superior in vacuum or inert atmosphere, in particular, performance of the polyacrylonitrile base is stable under high temperature condition, and it is the excellent thermal insulation material for Vacuum Furnace.

[PAN & rayon differences]

1.PAN (PolyAcrylNitrile) is lower in cost.

2.PAN has coarser fiber and larger fiber diameter = Lower Surface area.

3. PAN is stiffer and has an "ichier" feeling. Rayon is more flexable and less irritating to the skin.

4. Rayon is lower in Thermal Conductivity than PAN at temperatures greater than 1800°C.

For heat treating applications, PAN carbon felt is the best price.

For handling ease and ultra high temperatures, Rayon is the best choice.


PAN-based carbon felt are used as insulation in vacuum and protective atmosphere (non-oxidizing) furnaces and process equipment used in the heat treating, semi-conductor, ceramic, aerospace, defense, bio-medical appliance, and sintered metals industries.

These felts are also used as a cathode in flow battery applications and as a reaction surface for many other electro-chemical processes. Common consumer and industrial consumable uses are as welding blankets, plumber pads, glass blowing pads, wicks in ultralight stoves, and automotive exhaust lining.
