select accelerators for rubbers (zmbt) 2-mercaptobenzothiazole

accelerator: an accelerator is a material that, when mixed with a catalyst and resin, speeds up the chemical reaction between the catalyst and the resin (usually in the polymerizing of resin or vulcanization of rubbers). accelerators are also known as promoters when used with polyester resins and vulcanizing agents when used with rubbers.

vulcanization accelerators for tyre manufactures,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

benchmark for new elastomer compounds fst.com,benchmark for new elastomer compounds. weinheim, july 10, 2023. freudenberg new development for the vulcanization of chloroprene rubber eliminates the need for ethylene thiourea (etu) as an accelerator while still meeting the strict requirements of the automotive industry. with this innovation, the company follows its own sustainability

quickly and safely getting up to speed cordis,since the percentage of srm102 required compared to rubber content is similar to that of etu, the new additive is expected to have minimal effect on the final manufacturing cost. saferubber has delivered a safe and cost-effective alternative to the carcinogenic rubber vulcanisation accelerator additive etu.
