PTFE waterproof and breathable membrane is made of polytetrafluoroethylene (PTFE) material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
PTFE is a new type of material that has excellent high temperature resistance, high temperature resistance, low temperature resistance, alkali resistance, anti-aging, anti-oxidation and many other advantages.
Waterproof performance: Waterproofness means that water on the outside of the fabric will not penetrate the fabric and enter the interior.
The micropore diameter of PTFE membrane is 1/5000-1/20000 of the diameter of water droplets.
Therefore, even the smallest raindrops cannot pass through. In addition, the surface energy of the PTFE film is low, and water droplets cannot spread on the film, thus effectively preventing the penetration of water droplets.
Moisture permeability: The porosity of the ptfe waterproof and breathable membrane is as high as 80%, the average pore size is 0.2um, and the micropore size is 700 times larger than water vapor molecules, thus ensuring that water vapor molecules can pass freely.
During the stretching process, the ptfe waterproof and breathable membrane forms a microporous structure in which nodes are connected to countless microfibers. The microfibers form pores, and the pores penetrate each other to form a unique network structure, so that wind cannot directly pass through. , it will change direction and turn back when encountering an obstruction, effectively preventing air penetration.
