PTFE needled fabric is a kind of filter material which uses PTFE from THree-dimensional needing. PTFE fiber is macromolecule linear structure, so the PTFE needled fabric has excellent heat resistance, abrasion resistance, corrosion resistance and chemical stability, widely used in the iron and steel industry, power industry and waste incineration industry etc. under varieties of hostile flue gas enviroment.
