- Why do people use vulcanization accelerators?
- Hence, people generally use vulcanization accelerators to increase the speed, which promotes the development of the rubber industry. As an important part of vulcanization, vulcanization accelerator, such as diphenylguanidine (DPG) and dicumyl peroxide (DCP), can improve efficiency and reduce time and temperature requirements [ 12, 13 ].
- Is ZnO a good activator for rubber vulcanization?
- Actually, CdO showed better activating behavior in rubber vulcanization [ 38 ], but its higher toxicity precludes its use for substituting ZnO. Therefore, at the moment, ZnO still remains the most efficient activator of rubber vulcanization.
