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
