A polyurethane foam or elastomer comprises an organic polyisocyanate component, an active hydrogen-containing component reactive with the polyisocyanate component, wherein the viscosity of this component is less than about 500cP at room temperature, a catalyst component, a surfactant, and a flame retardant composition. The components may be low VOC. A preferred flame retardant composition comprises an antimony-based compound, a halogenated, active hydrogen-containing component reactive with the polyisocyanate component, and a halogenated flame-retarding agent. Such polyurethanes are useful as gasket, seals, padding, in automotive applications, and the like. |
