eptfe membrane for outdoor garment textiles
Huzhou Kaili New Material Technology Co., Ltd. manufactures specialized ePTFE (expanded Polytetrafluoroethylene) membranes engineered to withstand the unpredictable rigors of the outdoors. In the technical apparel industry, the membrane is the critical component that allows a garment to transition from a waterproof hardshell to a breathable performance layer. Our ePTFE technology provides a permanent, microporous barrier that facilitates massive moisture vapor drive while remaining 100% impervious to wind and high-pressure liquid ingress.
Operating from our 3,000m² facility in the Yangtze River Delta fluoromaterial cluster, we provide the stable, high-performance substrate necessary for durable 2-layer, 2.5-layer, and 3-layer outdoor composites.

Specialized Outdoor Applications
- Professional Mountaineering (3L): Maximum-durability hardshells designed for rock, ice, and high-altitude abrasion where the membrane is protected by a rugged face and tricot backer.
- Trekking & Hiking (2.5L): Ultra-thin, lightweight membranes compatible with "dry-touch" internal prints for packable, emergency rain shells.
- Ski & Snowboard Wear (2L): Balanced structures that provide high-load waterproofness for deep powder and superior flexibility for movement.
- Tactical & Field Jackets: Low-noise, high-strength membranes that provide a breathable yet impenetrable shield for professional outdoor operators.
