Vulcanization
Vulcanization is the process of converting raw rubber into rubber by heating it with sulfur. This process was developed by the American inventor Charles Gudier in 1844. Raw rubber has low strength and very sticky, especially when heated, and in the frost becomes solid and fragile. Therefore, for the manufacture of various products in raw form, rubber is not suitable. Its valuable properties rubber acquires during vulcanization, that is, when heated with sulfur. The vulcanized rubber is called rubber. In the process of vulcanization from rubber, sulfur and filler, produce a mixture that fills the appropriate forms and under pressure to heat.
