USE OF RECYCLED POLYOL FROM AMINE-BASED HYDROLYSIS PROCESS TO PRODUCE PU FOAM

Abstract: at least one polyol component reacts in a process for producing pu foams with at least one isocyanate component in the presence of one or more catalysts that catalyze the isocyanate-polyol and/or isocyanate-water reactions and/or isocyanate trimerization. the polyol component was obtained by hydrolysis of a polyurethane by contacting the polyurethane with water in the presence of an organic amine base.
