Ausfil:: Filter Media

PTFE felt filter material also called Teflon filter material, with a good performance in the temperature of 250° C, the instant temperature can up to 280° C. 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, as well as some high temperature or some corrosive liquid filtration.
