COMPOSITION SUITABLE FOR PREPARING POLYURETHANE OR POLYISOCYANURATE RIGID FOAMS

A process for producing polyurethane foam by reacting at least one polyol component with at least one isocyanate component in the presence of at least one blowing agent and of one or more catalysts that catalyze the isocyanate-polyol and/or isocyanate-water reactions and/or the isocyanate trimerizat...

More Information
Summary:A process for producing polyurethane foam by reacting at least one polyol component with at least one isocyanate component in the presence of at least one blowing agent and of one or more catalysts that catalyze the isocyanate-polyol and/or isocyanate-water reactions and/or the isocyanate trimerization, wherein the reaction is conducted in the presence of selected polyether-siloxane copolymers, is described.
