Rubber vulcanization accelerator industry by Johon in Spain

vulcanization accelerators

Vulcanization Accelerators

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.

The thiazoles are used for the vulcanization of thick articles, and as basic accelerator in EPDM compounds (ethylene-propylene-diene rubbers), in combination with mixtures of ultra-accelerators. In the vulcanization of neoprene or polychloroprene rubber (CR rubber) the choice of accelerator is governed by different rules to other diene rubbers.

sulfur vulcanization

Sulfur vulcanization

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.

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.

Vulcanization, chemical process by which the physical properties of natural or synthetic rubber are improved; finished rubber has higher tensile strength and resistance to swelling and abrasion, and is elastic over a greater range of temperatures. It was discovered in 1839 by Charles Goodyear.

Vulcanization of rubber by sulfur alone is a time-consuming process, resulting in poor mechanical properties due to oxidative degradation of rubber. As a result, vulcanization accelerators are increasingly being adopted in the rubber industry to boost the process with minimal rubber degradation.
