NITROGEN-FREE AND LOW-NITROGEN CROSSLINKING ADDITIVES FOR COLD BLOCK SOFT FOAM WITH IMPROVED COMPRESSION AND AGEING PROPERTIES

摘要

Process for producing cold-cure flexible slabstock PU foams by reaction of at least one polyol component and at least one isocyanate component in the presence of water and at least one catalyst and at least one crosslinker, wherein no nitrogen-containing crosslinkers having an expanded OH number above 1000 mg KOH/g are employed in a total amount >0.5 parts by weight, preferably >0.1 parts by weight, based on 100 parts by weight of polyol.
