An accelerator is defined as a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties of the vulcanized rubber.
Theory & Practice Of Vulcanization - Rubber Seals, Gaskets
Butadiene rubber (BR), Styrene-butadiene rubber (SBR), Isobutene-isoprene rubber (Butyl, IIR), and Nitrile-butadiene rubber (NBR), which are crosslinked by using sulfur as a vulcanizing agent. The basic ingredients for a sulfur cure are: Sulfur or sulfur donor (crosslinker), Zinc oxide and fatty acid (activator), Organic accelerator(s). Sulfur.
The function of rubber vulcanization accelerator
Before people do not realize the organic accelerator, rubber vulcanization accelerator is mainly used alone sulfur or a sulfur and inorganic accelerator.However, this process requires a lot of sulfur, and high curing temperature, as well as quite a long curing time, and the considerable risk of excessive sulfur.
Vulcanization & Accelerators
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

(PDF) Progress in Rubber Vulcanization Accelerator
Vulcanization, as the key step in rubber process, directly affects the processing and performance of rubber products. Compared with sulfur alone, the presence of small amounts of accelerator ...
The use of vulcanizing agent - rubber accelerator
The vulcanizing agent with the sulfur, and rubber accelerator MPMCZ or TMTD this initiator, can make vulcanization two of alkenes rubber can delay coke burning time, reduce heat, and set out strength, high resistance to sulfid ,for rubber high temperature curing (183 ° C), the amount of 2-3phr suitable for large tires and thicker, increase products.

Vulcanization mechanism of natural rubber.
History Of Vulcanization • Vulcanization Of Rubber Was Discovered In 1839 by the U.S. inventor Charles Goodyear. • Thomas Hancock (1786–1865), a scientist and engineer, was the first to patent vulcanization of rubber . • Hancock was awarded a British patent on May 21, 1844. • Three weeks later on June 15, 1844 Goodyear was awarded a ...
