Abstract: The invention relates to an underbody panel insulation for a motor vehicle made of one or more foamed viscoelastic polyurethane foam materials which can differ in zones (partially) over the surface and thickness of the insulation in its formulation and the physical and mechanical properties, and to a method for the production thereof.

Abstract: A damping element for a battery/accumulator system is arranged between the battery/battery system and a floor of a motor vehicle.

Abstract: The invention relates to a method for producing an absorbing sound insulation motor vehicle trim element having a four-layered structure made from a first foam layer, a second foam layer, a non-woven foam layer and a non-woven fabric layer. The invention further relates to an absorbing sound insulation motor vehicle trim element.

Abstract: Disclosed is an acoustically and thermally effective engine and/or aggregate capsule which completely encloses the engine and/or aggregate.

Abstract: A layer composite is a sandwich structure, in which a PUR foam layer is needle-punched with two nonwovens.

Abstract: The invention relates to a broadband sound absorber (1) which comprises a sound-absorbing filler material between two microperforated film webs (2) which are contiguous on their edges, said filler material optionally containing heavy fillers. The broadband sound absorber (1) achieves excellent acoustic insulation and has microperforations (4) all over or only in sections, said filler material optionally containing heavy fillers (mass density) and one or both microperforated film webs (2) having the same thickness across their surface or thickened portions (3, 5) of the same or a different material in some sections.
