FLEXIBLE WATER-RESISTANT COMPOSITES
Abstract:
This invention provides air impermeable liquid-water resistant water-vapor-permeable composites that have enhanced water-vapor-permeable properties. The composites comprise: a layer of a microporous polymer that is water-vapor permeable and which is liquid water-resistant. This layer is in contact with an air-impermeable, liquid water resistant, polymer layer that is permeable to water-vapor molecules. A third layer of a microporous, water vapor permeable, hydrophilic polymer is present on the other side of the air-impermeable polymer layer.
