Samenvatting

The invention relates to a method for producing rigid polyurethane foams, wherein a mixture of one or more highly functional polyether alcohols having functionalities of (3.5) to (5.5) and a hydroxyl value of (350) to (550) mg KOH/g, one or more polyether alcohols based on aliphatic and/or aromatic amines having functionalities of (3) to (4) and a hydroxyl value of (150) to (800) mg KOH/g, a fatty acid ester containing OH groups, and optionally one or more low-molecular-weight chain exten­ ders and/or cross-linking agents having functionalities of (2) to (3) and a molecular weight Mw < (400) g/mol is used as a polyol component. The obtained rigid polyurethane foams are characterized by good surface properties.
