<p>1,269,305. Electrically conductive elastomer compositions. KONINKLIJKE ZWAVEL ZUURFABRIEKEN. 1 Oct., 1970 [3 Oct., 1969], No. 46716/70. Headings C3P and C3Q. Electrically-conductive vulcanized elastomer compositions comprise, per 100 parts by weight of unvulcanized elastomer, 40-400 parts of an electrically non-conductive filler and 2-15 parts of gasification carbon. The filler may be of reinforcing or non-reinforcing type. In examples, compositions comprise natural rubber, SBR or neoprene as elastomer; carbon black, silica or clay as filler; gasification carbon; conventional vulcanizing agentsand one or more of the following ingredients: 2-mercaptobenzimidazole, phenyl - # - naphthylamine, a plasticizer sold under the Registered Trade Mark "Dutrex-55", diethylene glycol, triethanolamine and magnesium oxide.</p> |
