    Abstract: PROBLEM TO BE SOLVED: To obtain a polyurethane useful as a material for coating by reacting a specified polyhydric alcohol with an isocyanate. SOLUTION: This polyurethane which is suitable as a material or component of a coating material is obtained by reacting a prepolymer (a) obtained by reacting a polyhydric alcohol having more than one isocyanate-reactive hydroxyl group per molecule with an aromatic or aliphatic polyisocyanate in a ratio of the number of the isocyanatte-reactive hydroxyl groups to the number of the isocyanate groups of below 1 with an isocyanate selected from the group consisting of aromatic or aliphatic polyisocyanates (b) and a chain extender (2) obtained by reacting a polyhydric alcohol (a) with a compound (b) having an epoxy functional group and additionally an alcohol-reactive functional group, a reaction product (b) of the reaction product with an α,β-olefinically unsaturated carboxylic acid, and reacting this reaction product with an amine having a reactive prim. amino group.

    Abstract: A device comprising at least one base plate and at least one cover plate held in a frame with the void regions containing a microcellular filler uses carbon black to colour the filler. Also claimed is preparation of the device by gluing or welding the plates and frame together. Preferably long term thermal conductivity is less than 30 mW/m.K and long term thermal conductivity stability is more than 1a (1 year). The plates and frame comprise thermoplastic or foamed plastic, preferably hard polyurethane foam with an open cell structure. Metal oxide or (preferably) silica aerogel particles with an average size of 0.001-5 mm is used as the filler.
