Abstract
A flame retardant mixture, suitable for use in polyurethane foams, comprises a polybrominated diphenyl oxide (e.g., pentabromodiphenyl oxide) and an organic diphosphate (e.g., an aromatic diphosphate). A small amount of triaryl phosphate can also be present for viscosity reduction purposes.
