PTFE needle felt is a kind filter material which is made of PTFE (PTFE fiber) through three dimensional needling.PTFE fiber is a macromolecular linear structure,so it has a strong temperature resistance,wear resistance,corrosion resistance,chemical stability,widely used in iron and steel,electricity,garbage incineration and other harsh flue gas filter environment.
