Teflon waterproof and breathable membrane refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and processed by calendering, extrusion, and biaxial stretching.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
How is it waterproof and breathable? Let us find out together below.
? The working principle of Teflon waterproof and breathable membrane can be divided into two types: microporous and hydrophilic groups. The waterproof and breathable membrane uses the former, because the minimum diameter of water droplets is about 20 microns, and the diameter of water vapor molecules is only It is 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. Liquid water or water droplets prevent water molecules from passing through due to their surface tension, thus preventing water penetration. The breathable membrane has a waterproof function.
