Curing accelerator D and DPG are two commonly used rubber additives, which play an important role in rubber technology. Although they can all promote the vulcanization reaction of rubber, there are differences in some aspects. This article will introduce the difference between vulcanization accelerator D and DPG in detail to help you choose the vulcanization accelerator that suits you.

vulcanization accelerator D is a fast vulcanization accelerator. It can significantly shorten the vulcanization time of rubber and improve the efficiency of vulcanization. Vulcanization accelerator D is usually used for rubber products requiring rapid vulcanization. For example, in the manufacture of tires, a vulcanization accelerator D is usually used to accelerate the vulcanization reaction, thereby improving production efficiency. In addition, vulcanization accelerator D can also improve the strength and hardness of rubber products, increase its wear resistance and aging resistance.

In contrast, DPG is a slower curing accelerator. Its main function is to delay the vulcanization reaction, so that the rubber can be more fully crosslinked during the vulcanization process. Therefore, DPG is generally used for rubber products that require longer vulcanization times and better processability. For example, in the manufacture of rubber pipes, DPG is often used to delay the vulcanization reaction in order to better control the vulcanization process and improve the processability of the rubber.

In addition, vulcanization accelerator D and DPG also differ in application scenarios. Vulcanization accelerator D is stable at high temperature and is suitable for rubber products vulcanized at high temperature. DPG, on the other hand, has good activity at low temperatures and is suitable for low-temperature vulcanized rubber products. Therefore, when selecting the vulcanization accelerator, it is necessary to select according to the specific rubber process and application environment.

In summary, there are differences between vulcanization accelerators D and DPG in terms of vulcanization speed, processability and applicable temperature. Vulcanization accelerator D is suitable for rubber products that need fast vulcanization, while DPG is suitable for rubber products that need longer vulcanization time and better processing performance. When choosing a vulcanization accelerator, you can choose according to your own process requirements and application scenarios to obtain the best vulcanization effect and rubber product performance.
