| titleOfInvention | METHOD FOR PRODUCING HARD POLYURETHANE FOAMS |
| abstract | The invention relates to a process for producing rigid polyurethane foams having a low bulk density, good dimensional stability and high adhesive strength, which are preferably suitable for thermal insulation of Kuehlmoebeln and Gefriergutlagerschränken. The aim of the invention is to eliminate the disadvantages of conventional thermal insulation, in particular for refrigerated and frozen goods storage cabinets. The invention has for its object to produce a suitable reaction mixture can be made of the hard polyurethane foams with low bulk density, good dimensional stability and high adhesion. According to the invention, the object is achieved by the reaction mixture containing polyether alcohols or polyether alcohol mixtures having the functionality of at least 3, preferably at least 4, and using as catalysts or as a catalyst mixture those having a mild catalytic action. In the catalyst mixtures, at least 85% by weight should have a mild catalytic action. |
