摘要: This disclosure describes a method of making a polyurethane foam and a method of reducing NVH expected to be experienced by a substrate using the foam. When the foam is subjected to 95% relative humidity for a period of 7 days at a temperature of about 50° C., the foam absorbs an amount of water that is less than about 30% of the weight of the foam.

摘要: A polyurethane foam is disclosed and described. The polyurethane foam is formed by combining a first component comprising at least one polyol with a second component comprising at least one polyisocyanate. The ratio of the number of isocyanate equivalents in the second component to the number of hydroxyl equivalents in the second component is less than 1.0. The foam exhibits low levels of free diisocyanate monomer, thereby reducing the amount of hazardous, volatile organic compounds. As a result, the foam can be prepared and installed without the need for ventilation equipment, external sources of fresh air, and the like.
