eptfe membrane for outdoor performance fabrics
At Huzhou Kaili New Material Technology Co., Ltd., we specialize in the development and production of ePTFE membranes for outdoor performance fabrics, engineered to combine durability, waterproofing, breathability, and wind resistance in one advanced solution. Our membranes are made from expanded polytetrafluoroethylene (ePTFE) - a high-performance fluoropolymer known for its microporous structure, which allows water vapor to escape while blocking wind and rain. This makes it ideal for high-performance outdoor garments, including jackets, mountaineering gear, and active sportswear designed to perform in demanding conditions.
As a core member of Kaili Advanced Materials Group, our factory in Huzhou, Zhejiang Province spans 3,000 square meters and is equipped with advanced lamination, coating, and precision finishing lines. Located just 1.5 hours from Shanghai by high-speed rail, we ensure rapid global logistics and stable supply for OEM/ODM production. With over a decade of expertise in fluoropolymer membrane technology, we are committed to supporting textile manufacturers and apparel brands worldwide with innovative and reliable ePTFE solutions.
