    摘要: The present invention relates to a polyurethane foam which can be obtained by reacting at least one polyether polyol as component (A), at least one polyether polyol based on at least one amine as component (B), at least one polyester polyol as component (C) and at least one polyisocyanate as component (D), in the presence of at least one catalyst selected from the group consisting of salts of carboxylic acids having from 1 to 20 carbon atoms, amine-comprising compounds and mixtures thereof as component (E) and at least one blowing agent as component (F), wherein the ratio of OCN groups to OH groups (ISO index) is from 140 to 180. The present invention further relates to a process for producing said polyurethane foam, its use for insulation, in particular for the insulation of pipes, and also pipe insulation comprising a polyurethane foam according to the invention.
