STUDIES ON CONDUCTIVE SILICONE-RUBBER COMPOUNDS

The electrical conductivity of silicone rubber vulcanizates containing carbon blacks [e.g. acetylene black, lamp black, and ISAF (N-234) bla ck] were investigated. the change in electrical conductivity with vary ing amounts of carbon blacks and the temperature dependence was measur ed. The mechanical properties like tensile strength. tear strength, el ongation at break, hardness, etc., of the vulcanizates were determined . A comparative study of the electrical conductivity of the composites revealed that the electrical conductivity of the composites made with acetylene black was higher than that of the composites made of other blacks.
