ACCELERATORS polymers
•An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. •Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization thus improving 'aged' properties of the rubber vulcanizates.

In practice the most often used is diphenyl-guanidine (DPG) and N, N'-diorthotolyl guanidine (DOTG) eventually o-tolyl-biguanidine. Guanidines are slow accelerators with short induction period and broad vulcanization plateau and require the use of zinc oxide for activation. They have alkaline character.

The diphenylguanidine accelerator DPG (D) is mainly used as an accelerator for natural rubber and synthetic rubber. Adding the accelerator DPG to the compound filled with high white carbon black can significantly reduce the Mooney viscosity of the compound rubber. Increase vulcanization speed. The active agent
