More Information
Summary:The invention relates to a method for producing rigid polyurethane foams or rigid polyisocyanurate foams using certain polyether ester polyols (B) based on aromatic dicarboxylic acids, optionally additional polyester polyols (C) different from the polyols of component (B), and polyether polyols (D), wherein the mass ratio of the sum of components (B) and, if applicable, (C) to component (D) is less than 1.6. The invention also relates to the rigid foams that can thus be obtained and to the use thereof for producing sandwich elements having rigid or flexible cover layers. The invention further relates to the basic polyol components.
