In the vulcanized rubber network obtained by the above two combinations, the content of single bond and double bond accounts for more than 90%, and the network has little main chain modification. The utilization rate of sulfur in the vulcanization system is high, and it is called effective vulcanization system (EV).
Classification of vulcanizing agents. Vulcanizing agents can be divided into inorganic and organic two categories. 1.Inorganic vulcanizing agent. Sulfur, sulfur monochloride, selenium, tellurium and so on. 2.Organic curing agent. Sulfur-containing accelerators such as accelerator TMTD, organic peroxides such as benzoyl peroxide, quinone oxime
