Waterproof Air-Permeable Membrane

The Waterproof Air-Permeable Membrane is a cutting-edge material that combines exceptional Waterproofing with outstanding breathability. Unlike traditional barriers, this air permeable waterproof membrane effectively blocks liquid water while allowing air and moisture vapor to pass through. This ensures maximum comfort, safety, and performance in demanding environments.

As a high performance waterproof air-permeable membrane, it is widely applied in outdoor gear, sportswear, tents, medical devices, electronics, automotive components, and industrial protection systems. By using advanced ePTFE air-permeable waterproof membrane technology, it guarantees durability, thermal stability, and excellent resistance to harsh environments.

Key Features
