Poly-Fluoro membrane pleated filter is made of Hydrophobic or Hydrophilic Polytetrafluoroethylene(PTFE). PTFE are characterized by high chemical inertness. The Poly-Fluoro pleated filter cartridges arewidely used to filtrate the strong acid and base solutions that are used in wet etching, solvent striping, andcleaning manufacturing processes of semiconductor factory. The membrane has about 80 ~ 95% porosity, and the uniform pore size distribution. Moreover, the filtration area of each cartridge is as high as 0.8 m2(0.67 ~ 0.8 m2 for equivalent products of imported brands). Therefore, Poly-Fluoro PTFE membrane pleatedcartridge filter has high flow rate, low pressure drop , and long-life service.
