This invention relates to the discovery that the combination of tetrabenzylthiuram disulfide, cashew nut oil modified novolak-type phenolic resin, a bismaleimide compound and a sulfenamide compound provides for excellent vulcanization of rubbers and results in desirable final rubber vulcanizate physical properties in the absence of generating undesirable nitrosamines and fumes during processing and cure.
