Rubber accelerator refers to a rubber vulcanization accelerator. Rubber vulcanization mainly uses sulfur, but the reaction between sulfur and rubber is very slow, so vulcanization accelerators came into being. The accelerator added to the rubber compound can promote the activation of the vulcanizing agent, thereby speeding up the cross-linking reaction between the vulcanizing agent and the rubber molecules, and achieving the effect of shortening the vulcanization time and lowering the vulcanization temperature.

Rubber anti-scorching agent, that is, a substance that prevents early vulcanization of rubber compounds during processing.It generally includes nitroso compounds (such as N-nitroso diphenylamine, etc.), organic acids (such as benzoic acid, phthalic anhydride, etc.) and thioimidamides (such as N-cyclohexyl thiophthalic anhydride etc.)

With the progress and development of the aging process, the performance of rubber and its products will gradually decrease to completely lose the use value. In order to extend the service life of rubber products, some substances that can inhibit the aging process must be added to the rubber to extend the storage period and service life of rubber and its products. These substances are called antioxidants.

Rubber vulcanizing agents include elemental sulfur, selenium, tellurium, sulfur-containing compounds, peroxides, quinone compounds, amine compounds, resin compounds, metal oxides and isocyanates. The most commonly used are elemental sulfur and sulfur-containing compounds.
