POLYURETHANE FOAMS COMPRISING LIPID-BASED POLYOLS |
摘要 |
A method of making a polyurethane foam from a mixture of isocyanate modified polyol and foam-forming ingredients, wherein the isocyanate modified polyol is made by reacting at least one polyol with at least one multifunctional isocyanate, wherein the isocyanate modified polyol is a non-foamed polyol polymer having available OH groups, wherein the foam forming ingredients comprise at least a multifunctional isocyanate and a foaming agent, preferably water, and characterised in that (i) the at least one polyol from which the isocyanate modified polyol is made comprises at least one lipid-based polyol which has undergone reaction with the isocyanate in the presence of a PU gelation catalyst, and/or (ii) the isocyanate modified polyol is mixed with a lipid-based polyol prior to, or at the same time as, foaming. |
