US 2010/0305228 A1 · PROCESS FOR PRODUCTION OF FLEXIBLE POLYURETHANE FOAMS WITH LOW EMISSION

Abstract

The present invention provides a process for the production of polyurethane foams from A1 compounds which contain hydrogen atoms which are reactive towards isocyanates and have a molecular weight of 400-15,000, A2 optionally compounds which contain hydrogen atoms which are reactive towards isocyanates and have a molecular weight of 62-399, A3 water and/or physical blowing agents, A4 optionally auxiliary substances and additives, such as a) catalysts which differ from component A5, b) surface-active additives, c) pigments or flameproofing agents, A5 at least one tin(II) salt of carboxylic acids, the carboxylic acid having from 10 to 16 carbon atoms, and B di- or polyisocyanates, wherein the resulting polyurethane foams have low emission values and a good resistance to ageing.
