Abstract:
The invention relates to an additive suitable for increasing compressive strength during the production of polyurethane soft foam, which contains at least one compound (V) containing, (i) more than three hydrogen atoms which are reactive with respect to isocyanates, (ii) an average hydroxyl number, determined according to DIN 53240-1: 2013-06, from 110-280 mg KOH/g, preferably 120-250 mg KOH/g, and (iv) >50 wt.-% ethylene oxide bound in the molecule, wt.-% with respect to the total alkylene oxide, and to a method for producing polyurethane foams and to a polyurethane foam and to the use thereof as described.

Claim (Index 9):
The process according to  claim 7  for production of flexible polyurethane foams having\n a gas permeability (A) of 1 to 300 mm water column and preferably 3 to 250 mm water column, \n a density (B) preferably of 5 to 150 kg/m 3 , more preferably of 10 to 130 kg/m 3  and especially preferably of 15 to 100 kg/m 3 , \n a pore structure (C) preferably having 5 to 25 cells/cm, \n a compressive strength (D) of 0.1 kPa to 15 kPa, preferably 0.5 to 13 kPa and especially preferably 2 to 11 kPa, and \n preferably a cell structure (E) having an open-cell content of more than 80%, (A) to (E) each measured as specified in the description.
