Abstract (en)
[origin: WO2006042674A1] The invention relates to a method for production of rigid polyurethane foams by reaction of a) polyisocyanates with b) compounds with hydrogen atoms which are at least reactive with isocyanate groups in the presence of c) blowing agents, characterised in that the compounds with hydrogen atoms which are at least reactive with isocyanate groups comprise bi1) at least one polyether alcohol started with saccharose and/or sorbitol with a functionality greater than 4 and a hydroxy number in the range between 400 and 550 mg KOH/g, bi2) at least one polyether alcohol started with TDA with a hydroxy number between 120 and 240 mg KOH/g and an aromatics content of 6.5 to 15 wt. %, or a polyether alcohol started with TMP with a hydroxy number of 120 to 240 mg KOH/g and, optionally, bi3) at least one polyether alcohol started with a bi- or tri-functional alcohol with a hydroxy number of 300 to 600 mg KOH/g.
