PTFE sewage filtration membrane is a microporous membrane made by calendering, extrusion, biaxial stretching and other methods.
The porosity can reach more than 85%, and the air can flow smoothly.
The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above.
Protect electronic instruments from becoming unusable due to moisture or water.
Compared with other breathable filter materials, it has excellent air permeability. It is difficult to form a thick dust layer on the surface of the film, and the dust can be naturally peeled off.
