The addition of accelerator in rubber can promote the reaction between rubber and vulcanizing agent, improve the vulcanizing speed, reduce the vulcanizing temperature, shorten the vulcanizing time, reduce the amount of vulcanizing agent, at the same time the physical mechanical properties and chemical properties of vulcanizing agent are also improved.

B. Promoters play a decisive role in the coking performance. The correct choice of promoters is conducive to the mixing, rolling, extrusion and operation safety of rubber materials.General molding vulcanization requires a certain amount of coking time, and mold - free sulfur does not require too long coking time.
