Abstract (en)
[origin: WO2015158680A1] The invention relates to a method for sound-proofing and/or acoustically insulating metal components and/or plastics components. An insulating layer consisting of a foamed first thermoplastic polymer material is applied to the components and bonded thereto. A mass damping layer consisting of a second thermoplastic polymer material of a density of 1.5 to 5 g/cm3 is then applied to the insulating layer by direct extrusion at melt temperatures between 120 and 300° C as defined profile. The invention also concerns components produced by this method.
