Abstract:
The object of the present invention concerns a method for producing flexible polyester urethane foam with increased compression hardness, as well as flexible polyester urethane foam obtainable from the same.

Claim (Index 1):
A method for producing flexible polyester urethane foams, obtainable by reacting\n A) an isocyanate-reactive component comprising\n A1) 1 to 60 wt. % of a polymerpolyol component comprising at least one polymerpolyol with a hydroxyl value of 10 to 100 mg KOH/g, which contains as a filler 5 to 50 wt. % of a polymer and as a base polyol at least one polyetherpolyol and/or at least one polyether carbonate polyol with an ethylene oxide proportion of 30 to 90 wt. %, a propylene oxide proportion of 10 to 70 wt. % and a carbon dioxide proportion of 0 to 35 wt. %, based on 100 wt. % of propylene oxide, ethylene oxide and carbon dioxide in the polyetherpolyol or polyethercabonatepolyol or in their mixtures, \n and \n A2) 40 to 99 wt. % of a polyesterpolyol component comprising at least one polyesterpolyol with a hydroxyl value of 30 to 90 mg KOH/g, \n and, optionally, \n A3) one or more components having groups capable of reacting with isocyanates, wherein components A3) differ from A1 and A2; \n with B) one or more di- and/or polyisocyanates, C) water, and, optionally, D) physical propellants, and, optionally, E) excipients and additives.
