Soft Felt - Standard Carbon Felt
Production method:
The manufacturing methods are:
(1) needle punching after air-laid short carbon fiber;
(2) carbonization of pre-oxygen silk felt;
(3) pre-oxidation and carbonization of polyacrylonitrile fiber felt. It used as insulation material for vacuum furnace and inert gas furnace, hot gas or liquid, and molten metal filter material, fuel cell porous electrode, catalyst carrier, composite material lining and composite material of corrosion-resistant contain
