eptfe membrane for breathable clothing fabrics
Huzhou Kaili New Material Technology Co., Ltd. specializes in the production of ePTFE (expanded Polytetrafluoroethylene) membranes, the essential functional layer for high-end breathable clothing. Our membranes solve the fundamental paradox of performance apparel: they are completely waterproof to external rain and wind, yet highly permeable to internal perspiration vapor.
Produced at our 3,000m² facility in the Yangtze River Delta fluoromaterial cluster, our ePTFE films are engineered to maintain their performance under the mechanical stress of active use and repeated laundering.

Versatile Construction Solutions
Our ePTFE membranes are optimized for various garment lamination methods:
- 3-Layer (3L) Hardshells: Laminated between a rugged face fabric and a functional tricot backing for maximum durability in alpine environments.
- 2-Layer (2L) Lined Jackets: Bonded to the outer fabric only, providing a softer drape for lifestyle and fashion-focused performance wear.
- Workwear & Uniforms: Ideal for military and tactical apparel where the membrane must provide a barrier against wind, rain, and liquid chemicals.
