Rubber Vulcanization Accelerators - Emerald Kalama Chemical
Rubber and tire manufacturers rely on Cure-Rite Rubber Accelerators as a key part of the rubber vulcanization package. Cure-Rite accelerators control the rate of vulcanization, which can improve rubber manufacturing productivity and ensure the development of desirable properties―such as strength, elasticity, modulus, and oxidation stability―prior to curing.
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.
Vulcanization & Accelerators - Nocil Ltd
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
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 ...
Sulfur vulcanization - Wikipedia
Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of a variety of hardness, elasticity, and mechanical durability by heating them with sulfur or other equivalent curatives or accelerators. Sulfur forms cross-linking bridges between sections of polymer chains which affects the mechanical and electronic properties.
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 - 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.
