TeflonWaterproof and Breathable Membrane is a material that many users are interested in, because just from the name, it is hard to understand what the principle is. And this is the charm of science. We cannot easily understand its secrets, but today the editor will take you to unveil the mystery of this material.
On the surface, there are obvious pressure points on both sides of the waterproof and breathable membrane. That is because the production process is through hot pressing and compounding. Please note that it is not the dot pattern of the non-woven fabric itself, but the obvious overlap. Dot pattern. Tear open the waterproof and breathable film. First, the middle polymer layer should be a milky white and soft waterproof and breathable layer. Because it is compounded by hot pressing, there should be pressure points on this layer of film.
TeflonWaterproof 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 There is a huge difference between the diameters of about 0.0004 microns. Water vapor can pass through the microporous membrane through the principle of diffusion. The surface tension of liquid water or water droplets prevents water molecules from passing through, thus preventing water penetration and making the membrane unable to pass. The breathable membrane has a waterproof function.
It is an environmentally friendly material manufacturer that specializes in R&D, production and sales of Teflonwaterproof and breathable membrane. Our company is different from other manufacturers. Our company can according to the user’s requirements. By optimizing the combination of key technical parameters such as speed ratio, pressure ratio, and operating temperature, the air permeability, thickness, and void ratio can be adjusted online according to the ratio and pore-forming medium to meet your different requirements. Interested parties can enter the store for consultation.
