Abstract (en)

[origin: WO2015078801A1] The invention relates to a method for producing polyurethane soft foam by reacting an isocyanate component with a component which is reactive towards isocyanates. The component which is reactive towards isocyanates comprises a mixture of at least one polyether carbonate polyol and a polyether polyol as the constituents. In the component which is reactive towards isocyanates, the total proportion of polyether carbonate polyols is ≥ 20 wt.% to ≤ 80 wt.% and the total proportion of polyether polyol is ≥ 20 wt.% to ≤ 80 wt.%, based on the total weight of the provided polyols. The invention further relates to a polyurethane soft foam produced using said method.
