A thermally expandable composition includes at least one polymer P, at least one chemical blowing agent CBA, at least one physical blowing agent PBA composed of expandable microspheres, and at least one filler F. A damping element includes a first layer composed of an expansion material and a second layer composed of an acoustic damping material. The damping element is suitable for providing vibration and/or noise damped systems.

Expandable material with improved thermal insulation properties and use thereof

A device for deadening the sound of a component having a damping layer of a foamed material and a stiffening layer, which is fixedly connected to the damping layer and which is stiffer than the damping layer, wherein the damping layer is formed by a foamed hot-melt adhesive.

Device and method for sound deadening a component

A sound absorbing sandwich plate for attaching to a component includes a first layer and a second layer connected to the first layer in an areal manner characterized in that, at least partially, especially along the second layer at least an area-shaped mounting part is provided, which at its side facing the second layer has a plurality of engaging elements, which are engageable into the second layer.

Sound absorbing sandwich plate

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