ePTFE membrane layer
At Huzhou Kaili New Material Technology Co., Ltd., we specialize in the development and manufacturing of ePTFE membrane layers designed for advanced waterproof, breathable, and protective applications. Located in Huzhou, Zhejiang Province, our 3,000 m² production base sits in the heart of China's Yangtze River Delta fluoromaterial industry cluster, only 1.5 hours from Shanghai.
As a member of Kaili Advanced Materials Group, we are dedicated to producing high-quality fluoropolymer membranes through precision coating, lamination, and surface finishing. Our ePTFE membrane layers are widely used in outdoor apparel, uniforms, medical protection, and industrial filtration, combining superior functional performance with long-term durability.
Every membrane layer we supply is the result of controlled expansion and microstructure optimization, ensuring uniform porosity, high vapor permeability, and excellent liquid barrier capability.
