Promoters D and DM are commonly used chemical additives that play an important promoting role in the production process of rubber, plastics, and rubber products. Although they are all accelerators, there are differences in their effectiveness and scope of application

Promoter D is mainly used to promote the vulcanization of rubber products, which can effectively improve the vulcanization speed and degree, enhance product hardness and wear resistance, and improve the physical properties of the product. The accelerator DM is mainly used to promote the vulcanization of rubber and plastics, which has a certain promoting effect on the vulcanization speed and degree, and also helps to improve the thermal and processing properties of the vulcanized products

The use of accelerator D and DM is also different. Promoter D needs to be used in conjunction with vulcanizing agents, activators, and other rubbers, and is usually used in the vulcanization systems of natural rubber and synthetic rubber, with a narrow range of applications. And the promoter DM can be used in combination with various vulcanizing agents, activators, filler rubber, etc., with a wider range of applications. Therefore, when selecting accelerators, it is necessary to choose suitable accelerators based on specific products and production processes to achieve the best promotion effect

In addition, there is a difference in safety between promoter D and DM. Promoter D has a certain degree of irritation to the skin and respiratory tract. When using it, personal protective measures should be taken to avoid direct contact. Promoter DM has better safety and less irritation to the human body compared to promoter D

In summary, accelerators D and DM differ in their effectiveness, scope of application, and safety. Therefore, when selecting accelerators, it is necessary to make reasonable choices based on specific products and production processes. By selecting the right promoter, the quality and performance of the product will be effectively improved, providing strong support for the development of the enterprise.
