Abstract:
1. A polyurethane foam composition, comprising: a reaction product of a first component comprising at least one polyol and a second component comprising at least one polyisocyanate, wherein the ratio of the number of isocyanate equivalents in the second component to the number of hydroxyl equivalents in the first component is less than 1.0, and the at least one polyol comprises an amine-initiated poly (alkylene oxide) polyol, a polyhydric ether-initiated poly (alkylene oxide) polyol, and a carbohydrate-initiated poly (alkylene oxide) polyol, and the amine-initiated poly (alkylene oxide) polyol is present in an amount from about 10 percent to about 30 percent by weight of the first component and wherein the reaction product is a foam that has a weight, and when the foam is subjected to 95 percent relative humidity for a period of 7 days at a of about 50° C., the foam absorbs an amount of water that is less than about 30 percent of the weight of the foam.
