First of all, to reduce the amount of vulcanization accelerator, but this will lead to the physical properties of rubber products decline, it is very important to understand this, vulcanization accelerator used alone is rarely, mostly is the use of two, three accelerators and the way.Once there is a problem with the coordination, it is not possible to prevent the rubber from burning.

In the aspect of coordination, although as mentioned above, made a lot of discussion, but if still can not prevent coking, can add anti-coking agent (vulcanization delay agent).Vulcanization retarders are organic compounds of anhydrous phthalic acid and benzoic acid, nitroso compounds and phthalamines.Nitroso - diphenylamine can not be used in light - colored rubber Products propter suam pollutio {{V}}
The coke inhibitor also slows down vulcanization while delaying vulcanization because it reduces crosslinking, so do not use it in large quantities.In the authors' experience, the dosage should not exceed 0.4%.If it must exceed 0.4%, the amount of vulcanization accelerator should be reduced first.Do not use high promoter, high anti - coking agent method.
