PTFE needle felt also called Teflon, with a good performance in the temperature of 260 centigrade, the instant temperature can up to 280 centigrade. PTFE filter felt is a special material with a good alkali and acid resistance ,anti-hydrolysis ,stable physical dimension, so the ptfe filter bag mainly used in coal burning boiler, waste incineration ,carbon black producing,Tio2 producing for fume treatment or dust collection, as well as some high temperature or some corrosive liquid filtration.
