  • Patent number: 4174420
    Abstract: Flame resistance of upholstered furniture is significantly improved by interposing between the cover fabric and the padding or applying to the top side of the cover fabric a layer of neoprene foam capable of forming when exposed to a burning cigarette or under the conditions of a standard flame spread test, a thermally insulating char which does not smolder, and which maintains its structural integrity. The neoprene foam must be so formulated that it also is capable of evolving at combustion temperature sufficient amount of water to efficiently cool the affected area. Normally, the latex from which the foam is prepared is formulated with a char promoter and a hydrated inorganic compound. Upholstered furniture of this invention passes a burning cigarette test and performs extremely well in the flame spread test.
