Vulcanization accelerators D and DPG are two commonly used rubber additives that play important roles in rubber processes. Although they can all promote the vulcanization reaction of rubber, there are differences in some aspects. This article will provide you with a detailed introduction to the differences between vulcanization accelerators D and DPG, helping you choose the one that suits you best

Vulcanization accelerator D is a type of accelerator with a faster vulcanization rate. It can significantly shorten the vulcanization time of rubber and improve the efficiency of vulcanization. Vulcanization accelerator D is usually used for rubber products that require rapid vulcanization. For example, when manufacturing tires, vulcanization promoter D is usually used to accelerate the vulcanization reaction and improve production efficiency. In addition, vulcanization accelerator D can also improve the strength and hardness of rubber products, increase their wear resistance and aging resistance

Compared to DPG, it is a slower vulcanization accelerator. Its main function is to delay the vulcanization reaction and enable rubber to achieve more complete crosslinking during the vulcanization process. Therefore, DPG is usually used for rubber products that require longer vulcanization time and better processing performance. For example, when manufacturing rubber pipes, DPG is usually used to delay the vulcanization reaction, in order to better control the vulcanization process and improve the processing performance of rubber

In addition, the application scenarios of vulcanization accelerators D and DPG are also different. The vulcanization promoter D exhibits relatively stable performance at high temperatures and is suitable for rubber products that undergo high-temperature vulcanization. DPG has good activity at low temperatures and is suitable for low-temperature vulcanized rubber products. Therefore, when selecting vulcanization accelerators, it is necessary to choose 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, processing performance, and applicable temperature. Vulcanization accelerator D is suitable for rubber products that require rapid vulcanization, while DPG is suitable for rubber products that require longer vulcanization time and better processing performance. When selecting vulcanization accelerators, one can choose according to their own process requirements and application scenarios to achieve the best vulcanization effect and rubber product performance.
