Flexible polyurethane foams made from vegetable oil alkoxylated via dmc-catalysis

摘要

The present invention provides flexible polyurethane foams made from at least one polyisocyanate and at least one vegetable oil alkoxylated in the presence of a double metal cyanide (DMC) catalyst, optionally at least one non-vegetable oil-based polyol, optionally in the presence of at least one of blowing agents, surfactants, pigments, flame retardants, catalysts and fillers. The alkoxylated vegetable oils are environmentally-friendly, bio-based polyols which can be used to increase the "green" content of polyurethane foams without having detrimental effects on foam properties.
