Original Abstract Submitted
A process for producing PU foams using recycled polyols can be performed by reacting at least one polyol component, which has a recycled polyol, with at least one isocyanate component in the presence of one or more catalysts that catalyse the isocyanate-polyol and/or isocyanate-water and/or isocyanate trimerization reactions. The process also includes at least one foam stabilizer and optionally one or more chemical or physical blowing agents. The employed recycled polyol has toluene 2,4-diamine, toluene 2,6-diamine, 2,2′-diaminodiphenylmethane, 2,4′-diaminodiphenylmethane and/or 4,4′-diaminodiphenylmethane, and specifically in a total amount of 0.00001% to 0.4% by weight, preferably 0.00002% to 0.2% by weight, more preferably 0.00005% to 0.1% by weight, based on the total recycled polyol.
