  • Patent number: 11919994
    Abstract: The invention relates to a method for producing soft polyurethane foam obtained by reacting a composition containing a component A1 containing at least one filled polyol, a component A2 containing compounds reactive with isocyanates and having a hydroxyl value of ?20 to <100 mg KOH/g, the component A2 not containing any filled polyol, a component A3 containing water and/or at least one physical blowing agent, a component A4 containing auxiliary agents and additives, and a component B containing di- and/or polyisocyanates, characterized in that the reaction occurs in the presence of 0.5 to 3 parts by weight of an organic urea derivative as component C, which is obtained by reacting urea with a difunctional amine having a number-average molecular weight of 200 to 1000 g/mol. The invention also relates to a soft polyurethane foam obtainable by the method.
