Abstract: The invention relates to polyurethane gel materials containing finely-dispersed phase change materials (PCMs), (e.g. crystalline saturated hydrocarbons). Said materials permit a thermal regulation by means of thermal absorption and thermal dissipation in the phase transition range of the PCMs, which becomes apparent in terms of improved comfort in the use of the novel material for shoe soles, bicycle saddles, chair cushions or similar.

Abstract: Gel compositions based on reaction products of polyols and polyisocyanates contain as filler at least one pyrogenically produced oxide of a metal or metalloid. The gel compositions are used in structural parts or articles.

Abstract: The present invention relates to a coating system containing I) anhydrous, gel-like, high molecular weight polyurethane compositions, which may contain active substances, based on (1) 15 to 62 wt. %, based on the weight of 1) and 2), of a high molecular weight covalently crosslinked polyurethane matrix and (2) 38 to 85 wt. %, based on the weight of 1) and 2), of a liquid dispersing agent firmly bound in the matrix by secondary valence bonds, wherein the liquid dispersing agent contains one or more polyhydroxyl compounds having a number average molecular weight of 1000 to 12000 and an OH number of 20 to 112, wherein the dispersing agent is substantially free from hydroxyl compounds having a molecular weight below 800, and II) solvent-containing, solvent-free and/or aqueous polyurethane topcoats.

Abstract: The invention relates to a shaped body, in particular for a seat cushion, having a lower, supporting gel layer (2) which forms a lower covering surface (1), consists of a polyurethane gel and, on its upper side, has integral supports (3) which are spaced apart from one another via expansion channels (4) and on which a polyurethane foam layer (6) rests, the upper side (5) of which layer is covered by an upper covering (7).

Abstract: A polyurethane gel filled with an expanded calcium carbonate offers an improved material for various applications, wherein the advantageous gel properties are retained, but at the same time negative properties, such as relatively high specific weight and high thermal conductivity, are avoided.

Abstract: The composite material made from a polyurethane gel and coarse-grain solid particles distributed therein may be made to be visually appealing and at the same time facilitates utilization of the properties of a polyurethane gel in a novel composite material. The particles consist of cork, foam, textile materials etc.

Abstract: Polyurethane gel materials comprising finely divided Phase Change Materials (PCMs)—for example crystalline saturated hydrocarbons—facilitate heat regulation due to heat absorption and heat release in the phase transition range of the PCM, which improves comfort when using the gel material in items such as shoe soles, bicycle seats, chair cushions and the like.
