unveiling dpg rubber accelerator: features, applications, and supplier
2. characteristics of dpg: acceleration: dpg functions as a medium-fast primary accelerator, meaning it promotes the vulcanization process in rubber production. moderate reactivity: it offers a balanced level of reactivity, making it suitable for a wide range of rubber types, including natural rubber (nr), synthetic rubber, and blends.
rubber accelerator yusheng enterprise limited,rubber accelerators are chemical additives used in rubber compounding to speed up the vulcanization process. they promote the formation of cross-links between rubber polymer chains, enhancing the mechanical properties of the final product.

- Why is DPG used in silica-reinforced rubber compounds?
- Further, while reacting with the silanol groups DPG reduces the polarity of silica by being adsorbed onto the silica surface [, , ]; and finally, DPG is also capable of accelerating the silanization reaction [2,4,7,8]. DPG therefore has turned into a multi-purpose compounding ingredient in silica-reinforced rubber compounds.
- Does DPG promote silanization?
- This result indicates that the presence of DPG in the MB – independent from the concentration – promotes not only the silanization, but also the filler-polymer coupling reaction via the silane coupling agent (TESPT). This role of DPG will be discussed lateron in section 3.2.
- What are bound rubber contents based on DPG concentration?
- Bound rubber contents as function of DPG concentration in the MB; (): total bound rubber; (): chemically bound rubber; (): physically bound rubber. 3.1.3. Silica filler flocculation rate
- What happens if DPG blocks the access of silane molecules?
- If DPG blocks the access of silane molecules by absorption onto the silica surface, the vulcanization efficiency and crosslink density would be lowered as the amount of adsorbed DPG increases. As a consequence, a lower degree of silanization as well as a lower amount of chemically bound rubber would have been expected.
