Abstract: Polybutylene terephthalate can be used as a gas diffusion barrier for closed-cell rigid polyurethane foams. A thermal insulation element containing a closed-cell, rigid polyurethane foam, which is at least partially covered by a layer system containing at least one layer formed by a polybutylene terephthalate composition, is useful. Articles and devices may contain a corresponding thermal insulation structure, such as refrigerators, insulation panels, pipe insulations, water heaters, and thermally insulated transport boxes.

Abstract: Described herein is a process for preparing a polyurethane elastomer including the steps of (A) preparing an isocyanate prepolymer (a), where the isocyanate prepolymer has an isocyanate content in the range of ≥1 wt.-% to ≤9 wt.-%, and (B) preparing a reaction mixture by mixing at least one epoxy compound (b) with the isocyanate prepolymer (a) in presence of at least one catalyst (c), and where the amount of the alkali metal or alkaline earth metal salt is 0.00001 to 0.1 mol per kg of the total weight of the isocyanate prepolymer (a), the epoxy compound (b) and the catalyst (c), and heating the mixture to at least 80° C. to obtain the polyurethane elastomer. Also described herein are a polyurethane elastomer obtained by the process and a method of using the polyurethane elastomer as part of a roller or as a sealant.

Abstract: A process for producing an open-cell rigid polyurethane foam involves reacting at least the components of at least one polyisocyanate, a polyol composition, and a cell opening agent. The polyol composition contains at least 30% to 75% by weight of at least one polyether polyol (b-1) having a functionality in the range of 5.0 to 7.9 and containing monomeric units derived from monosaccharides, oligosaccharides, polysaccharides, and/or sugar alcohols; >0% to 69.5% by weight of at least one polyether polyol (b-2) having an OH number in the range of >0 to 250 mg KOH/g; and at least 0.5% by weight of water. The isocyanate index is below 160 and the concentrations in % by weight for (b-1), (b-2), and water are based on the total amount of the components of the polyol composition.
