And flame retardant polyurethane resin composition

The present invention provides various kinds of flame retardancy and excellent properties of polyurethane. Phosphoramide ester compound having a specific structure is used as a flame retardant for polyurethane foam or polyurethane elastomer with a flame retardant. By such a flame retardant material polyurethane resin (the polyol, polyisocyanate and various additives) were mixed, to give a polyurethane reactive species of raw material composition. Reactive urethane compound by reaction of the active hydrogen-containing polyisocyanate with a raw material composition, such as a polyol, a curing reaction, thereby obtaining a polyurethane foam composition or a polyurethane elastomer composition. The polyurethane foam or polyurethane elastomer, the resulting polyurethane resin composition having excellent flame retardancy and excellent in other properties.
