Abstract
A description is given of a method for the sound damping and/or sound insulation of metallic parts and/or plastic parts in which thermoplastic compounds are applied to the parts as a defined profile by direct extrusion at melting temperatures of between 120 and 300° C., wherein, before the heating, the compounds are in the form of granules with a density of 1.5 to 5 g/cm3.

A method for sound damping and/or sound insulation of metallic parts and/or plastic parts, characterized in that thermoplastic compounds are applied to the parts as a defined profile by direct extrusion at melting temperatures between 120 and 300° C., wherein, prior to heating for the direct extrusion, the compounds are present in the form of granules having a density of 1.5 to 5 g/cm3, wherein:
- the thermoplastic compound granules comprise a filled thermoplastic polymer comprising polyamide or bitumen, which is highly filled with inorganic salts, coated with a hot-melt adhesive based on polyamide or polyolefins.
