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.

Abstract: A sealing element includes: a waterproofing adhesive layer having first and second major surfaces, an adhesive layer covering at least a portion of the first major surface of the waterproofing adhesive layer, and a carrier layer on the side of the waterproofing adhesive layer opposite to the side of the adhesive layer, wherein the waterproofing adhesive layer is composed of a self-adhering bituminous composition and the adhesive layer is composed of a non-bituminous pressure sensitive adhesive. The sealing element is used as a waterproofing, roofing, vapor barrier, vapor retarder, or a façade membrane, or as a waterproofing, roofing tape, or façade tape.

Abstract: A vibration and noise damping element including a damping layer having first and second surfaces and an adhesive layer covering at least part of the first surface. The damping layer is composed of a damping layer material with a viscosity at 60° C. of 30′000-500′000 Pa*s containing at least one rubber component and the adhesive layer is composed of an adhesive layer material with a viscosity at 60° C. of 50′000-300′000 Pa*s containing at least one rubber component. The ratio of the thickness of the damping layer d1 to the adhesive layer d2 (d1/d2) is 0.6-4.0 and the sum (d1+d2) is 0.5-2.5 mm. The element shows good performance in the ball drop test at low temperatures, has good adhesion to the substrate it is applied to, provides good vibration and noise damping properties and guarantees easy separation after storage at temperatures between 30-50° C.
