In rubber vulcanization, all substances that can speed up the reaction rate of rubber and vulcanizing agent are collectively referred to as vulcanization accelerators,such as DTDC, DTDM and HVA-2.

Accelerator plays a very important role in rubber vulcanization. Adding a small amount of accelerator can greatly speed up the reaction between rubber and vulcanizing agent, increase vulcanization speed, reduce vulcanization temperature, shorten vulcanization time, reduce the amount of vulcanizing agent, and improve vulcanizate. It can improve the physical and mechanical properties of vulcanized rubber, such as improving tensile strength, constant elongation strength, abrasion resistance and hardness, etc., improving the aging resistance of vulcanized rubber, preventing blooming, expanding the use range of vulcanized rubber, and can produce transparent and various colors. of rubber products.
