The polyacrylonitrile-based graphite felt is stronger than the viscose-based graphite felt and has strong anti-oxidation ability, but it has poor flexibility, large bulk density and good insulation performance.

In addition to the high purity, high temperature resistance and non-melting properties of graphite, polyacrylictrile-based graphite felt has the advantages of elasticity, arbitrary folding, tailorability and suture of graphite yarn. The main purpose of graphite felt is to be used as insulation material for monocrystalline silicon smelting furnace.

In the chemical industry, the polyacrylonitrile-based graphite felt can be used as a filtration material for high purity corrosive chemical reagents. Under the condition of non-oxidizing atmosphere, the graphite felt can be used at temperatures up to about 3000℃.
