the present invention seeks to overcome the limitations of the prior art. the present invention provides a method for the production of a conductive foam having a surface resistance of not more than 9.9x10 ohms as measured by din #53 345, comprising compounding a latex of a rubbery polymer with up to 500 parts by weight of a particulate filler per 100 parts by weight of said rubbery polymer, a vulcanization paste, optionally a gelling system, and frothing the compound and applying it to a substrate; subjecting the foam to conditions which will cause it to set and drying and vulcanizing the foam, the improvement comprising incorporating into the compound at least 5 parts by dry weight per 100 parts by weight of said rubbery polymer of a dispersion of carbon black stabilized by a soap predominantly of the same type as that compatible with the process used to set the foam.
the present invention seeks to overcome the limitations of the prior art. summary of the invention the present invention provides a method for the production in the absence of isocyanates of a conductive foam having a surface resistance of not more than 9.9.times.10.sup.10 ohms as measured by din #53,345, comprising: (i) preparing a compound comprising per 100 parts by dry weight of an aqueous emulsion of a rubbery polymer emulsified with a soap, up to 150 parts by weight of one more particulate filters, selected from the group consisting of calcium carbonate, clay, talc, dolomite, barytes, aluminum trihydrate and glass microspheres; up to about 8 parts of a vulcanization paste; up to 10 parts by weight of a gelling agent and from 4 to 30 parts by dry weight of an aqueous emulsion containing up to 50 weight percent of carbon black emulsified with a soap; (ii) mechanically frothing said compound to a density from 80 to 600 g/1; (iii) forming said frothed compound to a desired shape (iv) gelling said frothed compound, and (v) vulcanizing said frothed compound.
