. Accelerators, in simplest terms, hasten the cleavage of the sulfur ring and formation of thiyl and polysulfenyl radicals.8 Sulfenamide accelerators such as N-cyclohexyl-2-benzothiazole sulfenamide (CBS) are safe-processing, delayed action accelerators, and are most widely used as primary accelerators due to their superior scorch safety. CBS is rarely used in sulfur cure systems without a secondary accelerator. The most widely used secondary accelerators with CBS are from the thiurams group. The thiuram accelerators, for instance tetramethylthiuram disulfide (TMTD), are fast curing, sulfur-bearing accelerators, and possess short scorch safety when used as a primary accelerator.9 In efficient cure systems (efficient vulcanization, EV), there is low level of elementalsulfur, i.e. 0.5 phr, with high accelerator content (5–6 phr). EV cure systems have predominantly high mono-sulfidic and little or no polysulfidic crosslink conten
