fireproof acid and alkali resistant Pre Oxidized PAN( PANOF) fabric felt

The felt is made of oxidized PAN short cut fiber.And after opening, carding,lapping,needling,it is made into a certain density and thickness.Then some excellent performances such as high purity,soft texture,and chemical corrosion resistance will be obtained by hot ironing,pressing,winding.Then after some special carbonization and graphitization process,it can be used as a filter,protection material in corrosive agent environment for its excellent resistance.And due to the excellentelectrical performance,the mat also widely used as electrode in flow battery.
