                                    PTFE Membrane


Polytetrafluoroethylene(PTFE)membrane belongs to microporous membrane, mainly including TF,NF,CF three series.


Of them:


TF is divided into hydrophilic membrane and functional hydrophilic membrane. Permanent hydrophilic membrane is mainly used in turbidity removal, clarification, absolute degermation and sewerage treatment in hydro products. Permanent functional hydrophilic membrane is used in proton conduction, electron conduction and ion exchange.

   NF is hydrophobic membrane, which is mainly used in turbidity removal, clarification, and absolute degermation in organic solvent products and particle removal and absolute degermationin in all kinds of gas.
   CF is hydrophobic membrane, which is mainly used in air dust removal and gas ultra-cleaning filtration and particle removal in high-temperature or high-corrosion air.
 typical most aperture includes 1.0,0.45,0.22,0.10m
