VAPOR-PERMEABLE, SUBSTANTIALLY WATER-IMPERMEABLE, CORROSION-INHIBITING COMPOSITES AND METHODS OF MAKING THE SAME

摘要

Vapor-permeable, substantially water-impermeable, corrosion-inhibiting composites are disclosed herein. For instance, disclosed herein are composites comprising a first layer comprising a first nonwoven; and a second layer adjacent to and mechanically integrated with the first layer, the second layer comprising a polymer having a melt flow index of about 10 g/10 mins to about 200 g/10 mins, and a corrosion inhibitor, wherein the composite has a moisture vapor transmission rate of from about 25 g/m2/day to about 1000 g/m2/day when measured at about 23° C. and about 50% relative humidity. Also disclosed herein are methods of making and using the same.
