Abstract: A water-blown, polyurethane foam modified by incorporation of specific zeolites at levels of from about 0.5 to ten parts per hundred parts polyol exhibit superior combustibility with no halogen or phosphorus flame retardant additive in the foam. Conventional halogen/phosphorus flame retardants, while providing a level of combustion resistance, generally lead to increased smoke containing noxious, and potentially toxic, combustion products.
