ABSTRACT:
Polyether flexible urethane foams are rendered flame laminatable by use of a combination of an organophosphorus additive to confer flame laminatable properties on the foam and a polyalkylene glycol additive to improve the flame laminatable properties. A halogenated flame retardant is preferably also contained in the foam.
