Sulfur Vulcanization polymerdatabase
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.
Rubber products cured with these curatives have excellent heat and water vapor resistance and thus, are often a good choice for rubber goods that are exposed to hot water and steam. However, these curatives are more expensive and also have a tendency to bloom to the surface. Sulfenamides Vulcanization Accelerator.

A vulcanization accelerator is typically used in combination with sulfur as the cross-linker, and with zinc oxide and stearic acid as activators. Other additives can be added too, but for the cross-linking reaction the abovementioned ones are the most important. The various types of rubber used in the various tire compounds all have different

RUBBER RECIPE FORMULATION Rubber is a product obtained by mixing elastomers with fillers and other ingredients followed by vulcanization. Vulcanization is used to impart to the rubber mechanical strength, high elasticity and resistance to solvents. The properties of rubber are determined by the properties and the relative amount of the main
