eptfe composite membrane material
At Huzhou Kaili New Material Technology Co., Ltd., we manufacture ePTFE composite membrane materials that combine high-performance expanded polytetrafluoroethylene (ePTFE) with advanced textile substrates to deliver durability, breathability, and protective properties. These composite membranes are engineered for applications where mechanical strength, waterproofing, and air/vapor permeability are essential, including protective clothing, outdoor performance fabrics, and industrial textiles.
Our factory, part of the Kaili Advanced Materials Group, covers 3,000 m² in Huzhou, Zhejiang Province, close to Shanghai for efficient global logistics. Equipped with advanced coating, lamination, and finishing lines, we provide OEM and ODM services, allowing customization of membrane thickness, porosity, and substrate type. With over 10 years of experience in fluoropolymer and membrane technology, we offer reliable solutions for textile manufacturers and apparel brands seeking high-performance ePTFE composites.
