The selection of the right rubber accelerator is a critical decision for any formulator aiming to optimize rubber compound properties and processing efficiency. Among the many options available, Diphenyl Guanidine (DPG) has established itself as a highly effective secondary accelerator, particularly in conjunction with thiazole and sulfenamide primary accelerators. From our position as a leading rubber chemical manufacturer in China, we’ve observed firsthand the significant advantages DPG brings to various rubber applications. This guide is intended for R&D scientists and procurement managers seeking to understand and integrate DPG into their formulations.

DPG, chemically known as 1,3-Diphenylguanidine with CAS 102-06-7, is renowned for its ability to accelerate the vulcanization process in natural rubber (NR) and styrene-butadiene rubber (SBR). Its role as a secondary accelerator means it synergizes with primary accelerators to achieve a faster cure rate and a more complete cross-linking network. This results in rubber products with enhanced mechanical properties, such as improved tensile strength, elongation at break, and resilience. When considering purchasing DPG, partnering with a reliable China supplier ensures access to a product that meets stringent quality specifications, crucial for achieving consistent performance in your compounds.

A key benefit of using DPG is its role in improving scorch safety. Scorch refers to the premature vulcanization of a rubber compound during mixing and processing stages. DPG, when used appropriately, provides a sufficient delay before the onset of vulcanization, allowing ample time for shaping and molding without compromising the final cure. This processing safety is invaluable, especially in complex manufacturing operations. By buying DPG, manufacturers can reduce the risk of costly scrap due to scorch.

Moreover, DPG offers good storage stability, which is a significant advantage for inventory management and maintaining product quality. This means that once procured, the DPG will retain its accelerating properties for a considerable period under appropriate storage conditions. This reliability is a key reason why many industries, including tire manufacturing and industrial rubber goods production, rely on DPG as a staple accelerator. Our commitment as a China-based manufacturer is to provide DPG that adheres to high standards of purity and consistency.

The versatility of DPG extends to its applications in various rubber types, including nitrile rubber (NBR), where it also demonstrates good performance. It is often used in products requiring dark or black coloration due to potential minor discoloration effects. Beyond its primary role as an accelerator, DPG can also act as a plasticizer in chloroprene rubber formulations when used with sulfur and TMTM. For procurement specialists, understanding these benefits helps in making informed decisions. As a prominent supplier in China, we offer competitive pricing and efficient logistics to ensure your DPG needs are met seamlessly.

In summary, Diphenyl Guanidine (DPG) is a powerful and versatile secondary rubber accelerator that offers numerous advantages for rubber compounders. Its ability to enhance cure rates, improve processing safety, and provide good storage stability makes it an essential component in many rubber formulations.
