Recent Advances on the Utilization of Nanoclays and Organophosphorus Compounds in Polyurethane Foams for Increasing Flame Retardancy

Abstract

Recent advances on fire retardants utilized in polyurethane foams were reviewed, mainly focusing on organophosphorus compounds. The application of nanotechnology for developing novel fire retarded nanocomposites is discussed as well, focusing in the addition of nanoclays to polyurethanes. The review is focused on flame retardants known or believed by the authors to be in actual use at the time of writing, without expanding on recent proprietary or patented information. Although fire retarded nanocomposite is an increasing area of research, still market utilization is to be developed.
