    Abstract: Rigid polyurethane foam is produced from mixtures of (b1) polyfunctional polyether-ols with OH numbers of 40-800 (including at least one with OH no. above 150) and more than 30 wt% ethylene oxide based on total alkylene oxide and (b2) polyether-ols with OH nos. above 40 based mainly on propylene- and/or butylene oxide, using PIR catalysts and an index of 80-500. A method for the production of rigid polyurethane foam with urethane and mainly isocyanurate groups by reacting (a) optionally modified polyisocyanates with (b) a polyol mixture and optionally (c) other compounds with isocyanate-reactive hydrogen atoms, in presence of (d) water, (e) catalysts, (f) fire retardants, (g) blowing agents and optionally (f) other additives etc. The polyol mixture (b) comprises (b1) di- to octa-functional polyether-ol(s) based on ethylene oxide (EO) and optionally propylene oxide (PO) and/or butylene oxide (BO), with an EO content of more than 30 wt% based on total alkylene oxide and an OH number of 40-800 mg KOH/g (including at least one polyether-ol (b1.1) with an OH number of more than 150), and (b2) polyether-ol(s) with an OH number of more than 40, based on PO and/or BO and optionally EO, and the foam is produced with a characteristic index of 80-500 in presence of PIR catalysts.. An Independent claim is also included for rigid polyurethane foam as above obtained by this method.
