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.

Polyurethane foam materials having reduced cold-flow effect and method for producing same

The present invention relates to a process for producing flame-retarded polyurethane foams, in particular flexible polyurethane foams, using halogen-free flame retardants, wherein the resulting flame-retarded polyurethane foams exhibit low emission values coupled with good mechanical properties. The present invention further relates to halogen-free flame retardants.

Method for producing flame retardant polyurethane foams using halogen-free flame retardants

The present invention relates to a method for producing flexible polyurethane foams, wherein an isocyanate component (component B) which comprises fatty acid derivatives comprising hydroxyl groups is used as starting substance. The flexible polyurethane foams according to the invention have a bulk density according to DIN EN ISO 3386-1-98 in the range of &#x2267;10 kg/mto &#x2266;150 kg/m, preferably &#x2267;20 kg/mto &#x2266;70 kg/m, and in general their compressive strength according to DIN EN ISO 3386-1-98 is in the range of &#x2267;0.5 kPa to &#x2266;20 kPa (at 40% deformation and 4th cycle). The invention also provides an NCO-terminated prepolymer comprising urethane groups obtainable by reaction of one or more polyisocyanates (B1) with one or more fatty acid derivatives comprising hydroxyl groups (B2).
