The process of converting plastic rubber to elastic rubber is called vulcanization. It is to add a certain curing agent such as sulfur, curing accelerator and so on into the semi-finished products made of raw rubber. In the vulcanization tank in the specified temperature heating, heat preservation of the raw glue between the linear molecules linked to each other into a three-dimensional network structure, so that the plastic glue is converted into high elastic vulcanized rubber.
Since the crosslinking is mainly composed of sulfur, it is called "vulcanization". With the rapid development of synthetic rubber now there are many varieties of vulcanizing agents except sulfur organic polysulfide, peroxide, metal oxides and so on. Therefore, all those can make the linear structure of plastic rubber into a three-dimensional network structure of elastic rubber process is called vulcanization.
