In the competitive landscape of chemical manufacturing, understanding the nuanced properties and applications of key industrial chemicals is paramount. Diphenyl Guanidine (DPG), known in the industry by its CAS number 102-06-7 and often referred to as Rubber Accelerator DPG, is a critical compound that plays a vital role in the rubber industry. This guide aims to illuminate its properties, diverse applications, and the advantages of procuring it from reliable suppliers, particularly those in China.

DPG is characterized as a medium-speed accelerator, a classification that signifies its ability to moderate the speed of rubber vulcanization. This controlled acceleration is crucial for preventing premature scorching during the mixing and processing stages of rubber compounds, while still ensuring efficient curing. Its chemical structure, C13H13N3, contributes to its effectiveness in promoting sulfur cross-linking, a process fundamental to rubber's transformation into a durable, elastic material. Key properties include a white or grayish appearance, a slight odor, and a melting point typically around 144°C. Its solubility in organic solvents like ethanol and toluene, contrasted with its insolubility in water, dictates its handling and formulation best practices.

The applications of Diphenyl Guanidine are extensive, primarily within the tire manufacturing sector. It is a preferred accelerator for natural rubber (NR), synthetic rubbers like SBR and NBR, and particularly for radial tires, where its 'slack effective and high-speed' characteristics are highly valued for optimizing production and ensuring product integrity. Beyond tires, DPG is also used in the manufacturing of various technical rubber products, including industrial hoses, conveyor belts, shoe soles, and other molded rubber goods where consistent quality and performance are essential.

For businesses looking to purchase DPG, understanding market dynamics and supplier reliability is key. China has become a global hub for chemical production, offering access to a wide range of DPG manufacturers. Sourcing from these suppliers often provides a competitive advantage, not only in terms of price but also in terms of product availability and scale. When selecting a supplier, it is advisable to look for those who can consistently deliver high-purity DPG (≥97%), provide detailed technical documentation like COAs and TDS, and offer responsive customer service and efficient logistics.

In essence, Diphenyl Guanidine is a cornerstone chemical for rubber manufacturers. Its ability to control vulcanization and enhance material properties makes it invaluable for producing high-performance tires and other rubber articles. By thoroughly understanding its specifications and strategically partnering with reputable Chinese manufacturers, companies can secure a cost-effective and dependable supply of this essential rubber additive, thereby boosting both their product quality and operational efficiency.
