PTFE is polytetrafluoroethylene, also known as Teflon (Teflon), is bag filter materials in the most high-end varieties of.PTFE bag for in resistance to corrosive conditions, the service life of the filter material requirements of occasions.

Polytetrafluoroethylene (PTFE) synthetic fiber filter bag is a bag made of special materials, in 240 DEG C temperature continuous operation, instant 260 DEG C temperature conditions, ability all pH range of acid-base erosion. PTFE synthetic fiber filter bag self-lubricating excellent, does not absorb moisture, can withstand ultraviolet radiation. But the wear resistance of PTFE fiber filter material generally, so the filter bag frame has more stringent requirements (finish).

PTFE filter bag used for coal-fired boilers, waste incineration, treatment of flue gas in the production of carbon black, titanium dioxide (TiO2) production process, for the first time in the smelting of some metals, refining and chemical production process have also been used.
