PU RIGID FOAM WITH LOW THERMAL CONDUCTIVITY AND GOOD THERMAL STABILITY |
摘要 |
The invention relates to a polyurethane foam that 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 with 1 to 20 C atoms, compounds containing amines, and mixtures thereof, as component (E), and at least one blowing agent as component (F), with the ratio of OCN groups to OH groups (ISO index) being between 140 and 180. In addition, the present invention relates to a method for producing this polyurethane foam, to the use of same for insulation, particularly for pipe insulation, and to a pipe insulator containing a polyurethane foam according to the invention. |
