PTFE flat membrane is a polymer compound of tetrafluoroethylene. The membrane pore size is small and uniform, the micropore structure is stable, the porosity can reach 80%~90%, the filtration efficiency can reach 99.999995%, and the filtration accuracy can Reach U15 level and above, even reach U17 level.
At the same time, the surface is water-repellent and has a very high water pressure resistance, so it has high waterproof performance.
