Rubber Processing Chemical – Vulcanization Accelerator in Japan

vulcanization accelerators

Vulcanization Accelerators

Vulcanization of rubber by sulfur alone is an extremely slow process and can take several hours at elevated temperature (140°C or more). This is problematic becasue long exposure to temperature and oxygen leads to oxidative degradation which, in turn, results in poor mechanical properties.

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.

Sulfur Vulcanization

The Invention of Vulcanization. The process of vulcanization was discovered by Goodyear in 1839. He found, by accident, that sulfur and white lead vulcanizes natural rubber. His discovery was a major technological breakthrough in the rubber-good industry and made the production of durable and waterproof rubber goods possible.
