Diphenylguanidine (DPG), identified by its CAS number 102-06-7, is a pivotal chemical compound in the realm of rubber manufacturing. Functioning primarily as a medium-speed accelerator, DPG plays a crucial role in optimizing the vulcanization process, thereby enhancing the performance and durability of a wide range of rubber products. For industry professionals seeking to understand and source this vital material, this overview provides essential information on its properties, applications, and market dynamics.

The chemical properties of DPG are key to its efficacy. It typically manifests as an off-white powder or granules, possessing a slight odor and a bitter taste. Its solubility characteristics, being soluble in many organic solvents but sparingly soluble in water, are important considerations for formulation and processing. As an accelerator, DPG is particularly valued for its ability to activate other accelerators, such as thiazoles and sulfenamides, leading to more efficient curing cycles and improved physical properties like tensile strength and abrasion resistance. This makes it an indispensable component in formulations for demanding applications.

The applications of Diphenylguanidine are diverse and critical to the rubber industry. Its most prominent use is in the manufacturing of tires, including those for passenger cars, trucks, and agricultural vehicles, where its consistent performance is highly valued. Beyond tires, DPG is utilized in the production of various industrial rubber goods, such as hoses, belts, footwear components, and rubber sheets. Its efficacy as a secondary accelerator allows manufacturers to fine-tune the vulcanization process, achieving a balance between processing safety and cure efficiency.

Market insights indicate a steady demand for DPG, driven by the growth in the automotive sector and the broader industrial rubber market. For procurement managers and R&D scientists, understanding the global supply chain, particularly the role of manufacturers in China, is crucial. Many Chinese suppliers offer high-purity DPG at competitive prices, often packaged in 20kg or 25kg bags. Key considerations when sourcing include purity levels (typically ≥97%), production capacity, adherence to quality standards, and the supplier's export experience. Engaging with established suppliers ensures a reliable supply of this essential chemical.

In essence, Diphenylguanidine is more than just a rubber additive; it is a critical enabler of performance and durability in countless rubber products. By appreciating its properties, understanding its wide-ranging applications, and leveraging the global market for efficient sourcing, industries can continue to benefit from this essential accelerator.
