Abstract

A foam material comprises a mixture of a foamable silicone resin and a powdered metal. The mixture may comprise 35 to 75% by weight of a methyl phenyl siloxane type of foamable silicone resin, the balance being powdered aluminium or stainless steel. The mixture is foamed by heating in air at 218 DEG C. for about one hour. The foaming may be promoted by the liberation of nitrogen gas from a bridged cyanidine compound of, for example, the structure shown: <FORM:0852887/IV(a)/1> The cyanidine compound is added in the proportion of 1/2 to 2% of the weight of the resin.ALSO:A mixture of powdered aluminium or stainless steel and 35 to 75% by weight of a foamable silicone resin is foamed by heating in air at 218 DEG C. for about one hour. The foaming may be promoted by the liberation of nitrogen gas from a bridged cyanide compound which is added in the proportion of 1/2 to 2% of the weight of the resin. Further heating for one hour at a higher temperature (540 DEG C. for the aluminium mixture or above 500 DEG C. for the stainless steel mixture) decomposes the resin and dimensionally stabilizes the expanded material.ALSO:A cellular material is formed by heating a mixture comprising powdered aluminium or stainless steel and 35 to 75% by weight of a foamable silicone resin in air at 218 DEG C. for about one hour to foam it. The foaming may be promoted by the liberation of nitrogen gas from a bridged cyanidine compound of, for example, the structure shown: <FORM:0852887/V/1> The cyanidine compound is added in the proportion of 1/2 to 2% of the weight of the resin. Further heating for one hour at a higher temperature (540 DEG C. for the aluminium mixture or above 500 DEG C. for the stainless steel mixture) decomposes the resin and dimensionally stabilizes the cellular material.
