Abstract: Polyurethane foam is produced by reacting isocyanates with an isocyanurate and/or biuret structure with polyols of molecular weight 400-8000 containing at least 50% primary hydroxyl groups plus compounds with primary amino group(s), optionally low molecular weight diols and/or triols as chain extenders or crosslinkers, tert. amine and metal salt catalysts and water. A process for the production of foam material based on polyisocyanate-polyaddition products by reacting isocyanates with NCO-reactive compounds in the presence of blowing agents, catalysts and optionally additives etc., using (i) isocyanates with an isocyanurate and/or biuret structure; (ii) a di- and/or poly-alcohol(s) with a molecular weight of 400-8000 in which at least 50% of the hydroxyl groups are primary OH groups; (iii) a compound(s) with primary amine group(s), optionally with diols and/or triols with molecular weights of less than 400 as chain extenders and/or crosslinkers; (iv) a tert. amine(s) and/or a metal salt(s) as catalysts; and (v) water. Independent claims are also included for (a) a foam obtained by this process; and (b) a cushion material based on these products.

Abstract: A process for the production of stable dispersions of ureas in polyols by adding NH-functional compounds (A) to polyols and reacting with isocyanates, in which compounds (A) are primary and/or secondary amines, alkanolamines and/or hydrazine derivatives and/or hydrazide derivatives together with monofunctional aliphatic amine(s). Independent claims are included for: (a) stable dispersions of ureas in polyols, obtained by this process; and (b) a process for the production of polyurethanes by reacting isocyanates with these polyurea dispersions in presence of blowing agents, catalysts and optionally fire retardants and other additives.
