vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. the chemical reaction between sulfur and the rubber hydrocarbon occurs mainly ac (doublet the c = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). the process takes around 6 hours at 140°C
vulcanization accelerators for Tire Manufacture,tbztd-70 accelerates the vulcanization of natural and synthetic rubbers with a high level of processing safety. tbztd-70 forms no carcinogenic nitrosamines. the addition of mercapto or sulfonamideaccelerators decelerates the vulcanization process. scorch and vulcanization times are reduced, the degree of crosslinking is sightly affected.
