eptfe barrier membrane for industrial fabrics
At Huzhou Kaili New Material Technology Co., Ltd., we specialize in producing ePTFE barrier membranes engineered for industrial fabrics that require outstanding chemical resistance, waterproofing, and durability. Our membranes are made from expanded polytetrafluoroethylene (ePTFE), featuring a microporous structure that effectively blocks liquids and particulates while maintaining air and vapor permeability. This makes them ideal for protective workwear, filtration textiles, and specialized industrial applications where safety and performance are critical.
As a subsidiary of Kaili Advanced Materials Group, our 3,000 m² facility in Huzhou, Zhejiang Province is equipped with advanced coating, lamination, and finishing lines. Strategically close to Shanghai, we ensure efficient global logistics, fast OEM/ODM production, and tailored membrane solutions for industrial textile manufacturers. With over 10 years of experience in fluoropolymer membrane technology, we provide reliable products that meet the highest performance standards.
