A condensation management apparatus comprises a microstructured film arranged to condense water vapor on an underside of a substantially horizontal surface. The film comprises channels disposed at least on a first major surface and configured to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the film. A capillary siphon structure of the film comprises a fold in the film, a condensate collection region proximate the fold, and a siphon region between the fold and a condensate release location of the film. At least a portion of a second major surface is attached to the underside of the substantially horizontal surface such that longitudinal openings of the channels of the condensate collection region are oriented towards a direction of gravity and the condensate release location is positioned lower along the direction of gravity than the condensate collection region.

The present invention relates to a composite comprising (1) a bottom layer comprising expanded thermoplastic elastomer particles; and (2) a surface layer on the bottom layer, and the use of such composites in flooring surfaces sports, sports hall floorings, swimming pool hall floorings, running tracks, sports facilities, playgrounds, kindergartens, park walkway and pavements.

A composite panel structure has opposing outer walls or surfaces and a core comprising a plurality of ribs extending between and connected to the outer walls and defining chambers which are filled with expanding foams, non-expanding foams, gases, or a combination thereof. The outer panel surfaces and internal chamber walls or ribs are made of woven or non-woven fibrous material impregnated with one or more resins. The panel structure may be used for making a variety of products including sports equipment such as sports paddles, surfboards, kite boards, skateboards, wakeboards, as well as construction panels for walls, ceilings or floors, display panels, panels for the vehicle industry, furniture, and other structures requiring high strength to weight properties.

A display board has a foam core with elastomeric properties with a first display layer affixed on one side and optionally a second display layer affixed on a second side. The elastic foam core can have a closed cell structure and be made from a thermoplastic. The display layers can be heat welded directly to the respective sides of the core with or without additional use of adhesive or the layers can be attached via adhesive only and not heat. The foam core has a Shore 00 hardness of 20-100.

A polymer floor element includes a decorative top layer on a substrate made of polymer. The floor element has a rectangular or square surface, for which it is valid that for a strip of the floor element with a first point Q defined as a vertex of the strip, and a point P at a distance of 40 cm with respect to Q along a side of the strip, suspended over a rod with diameter 2 cm with its side on which P and Q are defined, perpendicular to the axis of the rod, so that P is located in the vertical direction at the highest point where the floor element touches the rod. The strip, with point Q along one side, hangs down from the rod under the strip's own weight; the straight line PQ intersects the vertical through P at an angle less than 15°.

A fluid-filled chamber is provided and includes a first barrier layer, a second barrier layer, a foam structure, and a tensile member. The second barrier layer is secured to the first barrier layer to define an interior void between the first barrier layer and the second barrier layer. The interior void contains a predetermined volume of fluid. The foam structure and the tensile member are disposed within the interior void, whereby the tensile member includes a plurality of fibers extending in a first direction between the first barrier layer and the second barrier layer.

The present invention relates to a foam formed solid composite, comprising: a matrix phase consisting of a mixture of nanocellulose, at least one foaming agent, and optional additives, and a dispersed phase consisting of solid low-density particles having a density of less than 1.2 kg/dm.sup.3. The present invention further relates to a method and a liquid foam composition for manufacturing the solid composite.

A foam sheet core, including a plurality of foam sheet walls defining an array of hollow cells, wherein the plurality of foam sheet walls are bonded together to form the array of hollow cells, each of the plurality of foam sheet walls has a thickness from about 0.002 inches to about 0.08 inches, and each of the plurality of foam sheet walls has an average height from about 0.05 inches to about 5 inches.

This disclosure relates to a composite comprising (a) a rubber layer comprising a cured rubber and optionally a first copolymer having carboxyl groups or anhydride groups; and (b) a foam layer comprising a crosslinked ethylene vinyl acetate and optionally a second copolymer having carboxyl groups or glycidyl methacrylate groups; wherein the foam layer has at least one surface adhering to the rubber layer directly, and provided that either the first copolymer or the second copolymer is present, and the composite is free of glues or adhesive films in the interface between the rubber layer and the foam layer.

A surface covering is provided and includes an upper section of laminated polymeric layers and an acoustical section for dissipating sound waves.
