What are described are shaped hot-cure flexible PU foam articles, preferably mattresses and/or cushions, wherein the hot-cure flexible polyurethane foam has been obtained by reaction of at least one polyol component and at least one isocyanate component in the presence of at least one compound of formula (1a) and at least one compound of formula (1b) and at least one blowing agent and at least one catalyst.

Compression set

Described are (a) a process for production of polyurethane foam by reacting one or more polyol components with one or more isocyanate components, wherein wax having a congealing point in the range from 40&#xb0; C. to 90&#xb0; C. is employed as an additive, (b) a polyurethane foam obtainable by said process, (c) the use of waxes having a congealing point in the range from 40&#xb0; C. to 90&#xb0; C. as an additive in the manufacture of polyurethane foams to coarsen the foam structure, and also (d) a polyurethane foam production composition containing a wax having a congealing point in the range from 40&#xb0; C. to 90&#xb0; C.

PUR foam with enlarged cell structure

The invention relates to the use of metal salts of ricinoleic acid or solutions thereof in water or in organic solvents in producing polyurethane foams.
