Vulcanization & Accelerators Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links(of sulfur). The vulcanization process was discovered in 1839 and the individuals responsible for this discovery were

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.

Accelerator | rubber manufacturing | Britannica
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.. The use of alkaline compounds of metals as vulcanization accelerators ...
Vulcanization - an overview | ScienceDirect Topics
Vulcanization. Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.
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.

Charles Goodyear and the Vulcanization of Rubber
By Ann Marie Somma. Charles Goodyear’s discovery of the vulcanization of rubber—a process that allows rubber to withstand heat and cold—revolutionized the rubber industry in the mid-1800s.Automotive tires, pencil erasers, life jackets, balls, gloves, and more are all in commercial use because of Goodyear’s relentless experimentation to unlock the molecular structure of rubber—and to ...
US5602186A - Rubber devulcanization process
A process for devulcanizing a rubber vulcanizate by desulfurization involves suspending a rubber vulcanizate crumb in a solvent which preferably swells the rubber vulcanizate before or during the devulcanization reaction and adding an alkali metal, such as sodium, to the suspension. The alkali metal cleaves mono-, di- and polysulfidic cross-linkages in the rubber vulcanizate to liberate rubber ...
Vulcanization - Wikipedia
Vulcanization (British: Vulcanisation) refers to a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice.It has also grown to include the hardening of other (synthetic) rubbers via various means.
