NOISE ABSORBING/ISOLATING MATERIAL FOR AUTOMOBILE

摘要

PURPOSE: A noise absorbing/isolating material for automobile is provided to simplify a manufacturing process and to reduce the manufacturing cost. The manufacturing process may be simplified, since additional reinforcing material is not necessary by using polyurethane foam having excellent molding property and strength. CONSTITUTION: A noise absorbing/isolating material being mounted in the interior of a car or an engine room is featured in that a cover sheet(20) is layered and adhered directly to the outer surface of sheet(10) made of polyester based polyurethane foam without additional reinforcing materials.
