Abstract
An improved carpet padding comprises a layer of rebonded flexible polyurethane foam, a relatively thin intermediate layer of flexible prime polyurethane foam, and a top layer of polymer film. The layers are laminated together by either a flame or liquid adhesive method. In a preferred embodiment, the bottom layer of rebonded foam is from two to eight times as thick as the intermediate layer of prime foam, and the top layer of polymer film is a metallized polyester embossed with a uniform pattern.
