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
rubber vulcanization accelerator sunchem group,they can reduce the amount of sulfur yellow, shorten the vulcanization time, lower the vulcanization temperature, and at the same time improve the degree of vulcanization and the physicochemical properties of the vulcanized rubber. the first accelerator, aniline, was discovered by ornsco and gave a strong impetus to the development of rubber
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.

- 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 are vulcanization accelerators & activators?
- For sulfur yellow vulcanization systems, vulcanization accelerators and activators are essential. They can reduce the amount of sulfur yellow, shorten the vulcanization time, lower the vulcanization temperature, and at the same time improve the degree of vulcanization and the physicochemical properties of the vulcanized rubber.
- What are the different types of vulcanization accelerators?
- Vulcanization accelerators widely used in industry can be divided into three series: (1) guanidine based accelerators, such as diphenylguanidine (DPG); (2) dithiocarbamic acid based accelerators, such as TMTD; and (3) 2-mercaptobenzothiazole based accelerators, such as MBTS.
- Should rubber vulcanization accelerators be discontinued?
- With the rapid growth in global demand for rubber products, the safety and environmental concerns of rubber vulcanization accelerators are becoming more prominent, and many countries have decreed that the production and use of certain accelerators that are carcinogenic or suspected of being carcinogenic should be discontinued.
