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 14):
Use of an additive according to  claim 1  for improving the hardness of flexible polyurethane foam with retention of an adequate open-cell content, especially with avoidance of a reduction in the TDI index or in the amounts of catalyst, and/or for improving the ageing properties of flexible polyurethane foam in the course of foam production in each case.
