Select Accelerators for Rubbers - SpecialChem

An accelerator is a material that, when mixed with a catalyst or a resin, speeds the chemical reaction between the catalyst and the resin. Therefore, accelerators are not usually employed alone, but they are used within a cure package.

5 most common questions about rubber accelerator

5 Most Common Questions About Rubber Accelerator

Sulfur is a common accelerator, but it is slow in the production of vulcanizates. The accelerator increases the rate of cross-linking between rubber molecules, shortening the vulcanization time. At the same time, it reduces the temperature. There are three main types of accelerators: sulfenamides, thiurams, and dithiocarbamates.

accelerator, in the rubber industry, any of numerous chemical substances that cause vulcanization ( q.v.) of rubber to occur more rapidly or at lower temperatures. Many classes of compounds act as accelerators, the most important being organic materials containing sulfur and nitrogen, especially derivatives of benzothiazole.

Workers in the rubber manufacturing industry who are exposed to chemical accelerators and additives in the development of rubber products are at greater risk of developing cancers. According to Loomis (2018, et.al), types of cancers connected to chemicals and chemical mixtures include tumours of the lymphohaematopoietic system (25%), bladder (20%), lung (15%) and skin (15%).

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¡ãC for completion, which is uneconomical by any production standards.

The rubber accelerators (thiurams, carbamates, thiazoles, and thioureas) cause the greatest amount of sensitivity among users of rubber products; in contrast, workers involved in the manufacture of rubber are more likely allergic to the amine antioxidants. Vulcanization produces new allergens.
