Abstract

Elastic, open-celled, flexible PUR foams are produced by reacting a) polyisocyanates with b) a mixture containing 1. from 0.5 to 20% by weight of a polyether containing at least two hydroxyl groups and having an oxyethylene group content of >50% by weight and a mean molecular weight of from 400 to 10,000, 2. from 99.5 to 80% by weight of a product of the addition reaction of alkylene oxide with glycerol, optionally blended with ethylene glycol, having a mean molecular weight of from 400 to 10,000 and containing a maximum of 20% by weight of oxyethylene groups, in the presence of c) water and optionally organic blowing agents, and in the presence of d) catalysts, optionally in the presence of e) compounds containing at least two hydrogen atoms which are reactive towards isocyanates, and having a molecular weight of from 32 to 399, and f) surface-active or flame-inhibiting additives known per se and further auxiliaries known per se, where the reaction is carried out in a characteristic number range of from 95 to 110.
