Abstract
An acoustic damping material includes at least one polybutadiene PB, at least one at 25° C. liquid rubber LR, at least one butyl rubber BR, at least one natural or synthetic polyisoprene PI, at least one hydrocarbon resin HR and at least one solid particulate filler FM. 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 is used for damping of vibrations and noise in transportation vehicles and white goods, and a vibration and noise damping element include an adhesive layer composed of the acoustic damping material, and a method for applying a vibration and noise damping element to a noise emitting surface of a substrate, and a vibration damped system include a substrate and the vibration and noise damping element bonded to a noise emitting surface of the substrate.
