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

classification of rubber vulcanizing accelerators rubber accelerator
in the production of rubber tires, there are three commonly used rubber vulcanization accelerators, which are similar in appearance (i.e., 2-mercaptobenzothiazole, 4,4′-dimorpholine disulfide and tetramethylthiuram monosulfide). since rubber vulcanization accelerators have a great influence on the properties of vulcanized rubber, it is necessary to classify and identify these three commonly used rubber vulcanization accelerators.

zinc oxide rubber vulcanization review the importance of,zinc oxide (zno) is one of the most im-portant compounding ingredient in rubber technology. the review paper discusses the importance of zno in rub-ber technology. the various functions of zno both in dry rubber and latex for-mulations were discussed. the mecha-nism of action of zno in vulcanization chemistry was highlighted.
- What vulcanizing agent is used in rubber?
- Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
- What is accelerator in rubber vulcanization?
- An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates.
- What role does ZnO play in rubber vulcanization?
- ZnO plays a role in activating the function of accelerators in rubber vulcanization by transforming them into a more soluble salt-like compound [15, 16]. Frenkel and Kuz’minskii studied this role in thiuram (TMTD) based vulcanization in 1963.
- What determines vulcanization rate?
- The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate. Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur.
