Abstract
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.
