PTFE water-resistant filter membrane refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and processed by calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, and the porosity can reach 50%–80%.
Since the minimum diameter of water droplets is about 20 microns, while the diameter of water vapor molecules is only about 0.0004 microns, there is a huge difference between the diameters of the two. Water vapor can pass through the microporous membrane through the principle of diffusion, and the liquid state Due to the surface tension of water or water droplets, water molecules cannot pass through, which prevents water penetration and makes the PTFE washable filter membrane waterproof.
