Abstract
The invention relates to flame suppression compositions including an inorganic halogen-containing component including bromine, iodine, or a mixture thereof, and an organic binder system having a heat of formation of less than about 200 cal/g, wherein the composition is solid at a temperature below 100.degree. C. and combusts at a temperature between about 160.degree. C. to 1200.degree. C. to produce a plurality of reaction products capable of suppressing a flame upon application thereto and wherein substantially all the halogen is converted to a solid form after suppressing the flame. The invention also relates to methods of suppressing flames by combining an inorganic halogen-containing component including bromine, iodine, or a mixture thereof, with an organic binder system having a heat of formation of less than about 200 cal/g to form a solid composition, generating a plurality of reaction products from the composition in a substantially gaseous form, wherein the reaction products have a velocity, and applying the reaction products at a temperature of between about 160.degree. C. to 1200.degree. C. to at least one flame in an amount sufficient to suppress the flame, wherein subs…
