Abstract (en)
[origin: WO2017021439A1] Method for producing flexible polyester urethane foams with increased compressive strength. The invention relates to a method for producing flexible polyester urethane foams with increased compressive strength, obtainable using a polyol component A that contains: A1) a polymer polyol with a polyoxyethylene polyoxypropylene polyether as a base polyol, and A2) a polyester polyol with a hydroxyl number of 30 to 90 mg KOH/g; as well as to the flexible polyester urethane foams obtainable therefrom.
