PTFE black film made by biaxial stretching method.
The surface of the membrane can reach more than one billion micropores per square centimeter. The diameter of each micropore (0.1μm-0.5μm) is hundreds of times smaller than the diameter of water molecules (20μm-100μm) and smaller than the diameter of water vapor molecules (0.0003 μm-0.0004μm) is tens of thousands times larger, allowing water vapor to pass through, but water droplets cannot pass through. This microporous structure can be used to achieve excellent waterproof and breathable functions.
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
