Teflon waterproof and breathable membrane is a porous functional material with a porosity of up to 90%. Its spatially cross-linked pores form a three-dimensional spatial network structure, and form a pore diameter with an average micron size, which is between the size of gas molecules and liquid substances, so it can be waterproof and breathable.
High-quality jackets will have a multi-layer structure. Take the four-layer structure as an example: the outermost layer is a waterproof coating invisible to the naked eye, which provides the first line of defense; followed by a nylon layer, which provides durable functions; the middle layer is a thin film, which is the second line of defense for waterproofing and breathability. ;The innermost layer is nylon or artificial fiber to ensure the integrity of the film and provide comfort.
Teflon waterproof and breathable 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.
It is an environmentally friendly material manufacturer specializing in R&D, production and sales of Teflon waterproof and breathable membranes. 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. </p
