摘要： An article, specifically a sealing gasket, includes at least one layer of microporous expanded polytetrafluoroethylene (ePTFE) and at least one air permeable layer. The sealing gasket simultaneously provides for the passage of air through the gasket while limiting the passage of liquid through the gasket. The sealing gasket may be used between two components that require air flow between the components while limiting the passage of liquid between the components. In one aspect, the air permeability is at least 0.01 cubic feet per minute (CFM) per square foot as determined by ASTM D 737 testing.

摘要： Composite membrane materials and process for their production. The process entails the use of at least first and second porous membranes formed of a polymeric material and at least a third porous membrane formed of the same polymeric material, but having larger pores than the first and second porous membranes. The first, second and third porous membranes are laminated together by applying heat and pressure to the first, second and third porous membranes without applying a separate adhesive material therebetween. The laminated first, second and third porous membranes form a composite membrane in which the third porous membrane is between the first and second porous membranes.
