The invention relates to a method for producing a sound insulating component (1), in particular a trim part (2), for a motor vehicle, wherein the component is made of a plurality of layers (4,5), and wherein a first layer (4) consists of a first Polyurethane foam having a first density, and wherein on the first layer (4) a second layer (5) of a second polyurethane foam having a second density different from the first layer (4) is produced, and wherein the first and second layers (4,5) are each made with polyol material and isocyanate material. It is contemplated that the first and second layers (4,5) are each made with a ratio of polyol material to isocyanate material of 2: 1. |
