| description | The present invention provides self-extinguishing flexible polyurethane foams, reaction mixtures and methods for making them, wherein the foam forming reaction mixture comprises an isocyanate component of one or more aromatic polyisocyanate containing two or more aromatic or phenyl groups, and an aromatic phosphorus containing flame retardant, and, separately, a polyol component which is a mixture of one or more, first polyols and one or more high molecular weight polyols, and from 7.5 to 17.5 wt. %, based on the weight of the polyol component, of a brominated polyether flame retardant having a bromine content of from 30 to 40 wt. %, and having an average hydroxyl functionality of from 2.3 to 3.5, one or more catalysts, and one or more blowing agents. The flexible polyurethane foam has a gross density of from 200 to 280 g/l. |
