Abstract (en)
[origin: WO2019180156A1] The invention relates to a method for producing polyurethane soft foams having a volumetric weight according to DIN EN ISO 845: 2009-10 from 50.0 to 80.0 kg/m3, in particular open-cell polyurethane soft foams based on polyether polyol and toluylene diisocyanate, having a high bulk density, wherein the resulting polyurethane foams have similar properties to the already known polyurethane soft foams, these being simpler and more sustainable in terms of their production.
