PTFE waterproof and breathable membrane adopts special processing technology and is a microporous film made 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, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
At the same time, the pore diameter is thousands to tens of thousands of times the diameter of water droplets, preventing moisture from passing through, effectively protecting sensitive components, avoiding liquid erosion, and extending the service life of the product.
As a functional fabric, waterproof breathable fabric can isolate the human body from rain, snow, and chemicals while transmitting water vapor to the outside world in harsh environments.
The performance differences of ptfe waterproof and breathable membrane determine the final application scope.
The waterproof and breathable fabrics used in outdoor sports and leisure clothing must not only have a certain waterproof and breathable effect, but also must have a certain degree of comfort.
? It has a complete set of domestic advanced production equipment and adopts advanced production technology. Its products have passed ISO9001 quality management system certification. The testing standards strictly follow the EU standard EN1822. Membrane products are tested using the MPPS method.
