The graphite felt is normally classified into PAN based and pitch based graphite felt.It can also be classified into soft felt and hard felt by hardness.The mainly application is electric conduction in the photovoltaic industry, as the heat retaining material, thermal insulation material for the smelting furnace and vacuum furnace, and in chemical industry it could be the filtration material.
