Abstract: An acoustic damping material includes a binder matrix which includes a bitumen component or a polymer component, and a filler component that includes at least one solid particulate cellulose-containing filler. The acoustic damping material is suitable for use in damping of undesired vibrations and noise in mechanical structures and components of manufactured articles. The acoustic damping material may be applied to damping of vibrations and noise in transportation vehicles and white goods, to a vibration and noise damping element including a damping layer composed of the acoustic damping material, to a method for applying a vibration and noise damping element to a noise emitting surface of a substrate, and to a vibration damped system comprising a substrate and the vibration and noise damping element bonded to a noise emitting surface of the substrate.

Abstract: A bitumen-free acoustic damping material includes at least one thermoplastic polymer, at least one hydrocarbon resin, and at least one solid particulate filler.

Abstract: An adhesive element including a cover layer and a self-adhering sealant, wherein the self-adhering sealant is a thermoactive or thermoactivated rubber compound.

Abstract: A front lid for a vehicle, especially a motor vehicle, which front lid includes an outer panel, where, in a predetermined region or in the entire area of the front lid below the outer panel, at least one inertia mass is arranged, and the inertia mass is formed of a flexible heavy layer.

Abstract: The invention relates to a method for the reduction of the natural vibration (resonance) of a component (2). According to the invention a vibration behavior of component (2) is determined, wherein to each of the positions having vibration amplitudes, which exceed a preset threshold value, an attenuation element (1) is locally mounted, which is formed as a multilayered adhesive element including a support layer (1.1) and a self-adhesive damping mass. Moreover the invention relates to an attenuation element (1) for the reduction of the natural vibrations of a component (2). According to the invention the attenuation element (1) is formed as a multilayered adhesive element of a support layer (1.1) and a self-adhesive damping mass (1.2), wherein the support layer (1.1) is formed of a bend-resistant material and the damping mass (1.2) preferably is formed of butyl rubber.

Abstract: An acoustically effective, bituminous mass which can be applied hot by means of a flat extrusion mold contains an addition of a thermosetting resin or thermosetting reagent combination, plus bitumen, polymers and/or wax as well as fillers such as aluminum powder or zinc powder, powdered graphite or mica powder. This addition is added to the mass at temperatures under 125° C., so that the polymerization reaction does not occur until a subsequent heating.
