Abstract: A multilayer damping material for damping a vibrating surface comprising: at least one constraining layer; at least one dissipating layer; and at least one kinetic spacer layer comprising multiple spacer elements. The kinetic spacer layer is arranged between the constraining layer and the vibrating surface, when used for damping the vibrating surface. Each spacer element has opposite ends. At least one end of each of the multiple spacer elements is embedded in, bonded to, in contact with, or in close proximity to the dissipating layer, such that energy is dissipated within the multilayer damping material, through movement of the at least one end of each of the multiple spacer elements.

Abstract: A pressure sensitive adhesive composition is described comprising a first block copolymer comprising polyvinyl aromatic end block and poly(vinyl aromatic/butadiene) copolymer block; at least 20 wt. % of a second polystyrene-polyisoprene-poly styrene block copolymer; and solid tackifying resin. The total amount of block copolymer typically ranges from 40-65 wt. % and plasticizing oil and liquid tackifying resin are present in a total amount of less than 20 wt.-% based on the total weight of organic components of the pressure sensitive adhesive composition. Also describe are adhesive articles and methods.

Abstract: Panels comprising first and second layers and a core disposed there between, wherein the core has a plurality of walls providing a series of connected cells, wherein some of the cell walls have openings providing fluid communication between a series of at least 3 cells, and wherein the opening in a cell wall has an area that is at least 50 percent of the area of a side of that cell wall. Exemplary embodiments of panels described herein can be formed articles such as panels, walls, or other parts with curved surfaces. In one exemplary method, panels are shaped via thermoforming. In another exemplary method, panels are shaped via insert molding to provide the article. In another exemplary method, panels are shaped via compression molding to provide the article. The panels are useful for absorbing sound in a designed frequency range.
