PTFE filter material also called Teflon,with a good performance in the temperature of 260 centigrade,the instant temperature can up to 280 centigrade. PTFE is a special material with a good alkali and acid resistance,anti-hydrolysis,stable physical dimension, 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.
