In the demanding world of lubricants, maintaining performance under extreme conditions is paramount. Oxidative degradation is a major enemy, leading to increased viscosity, sludge formation, and ultimately, equipment failure. This is where high-quality antioxidants play a crucial role. For manufacturers and formulators seeking to enhance the longevity and effectiveness of their products, understanding the properties and sourcing of key antioxidants is vital.

Dioctyldiphenylamine (CAS 101-67-7) stands out as a highly effective antioxidant for a wide range of lubricating oils, including mineral and synthetic bases. Its exceptional resistance to heat and oxidation makes it a preferred choice for applications subjected to high temperatures, such as aviation engine oils. By scavenging free radicals, it significantly retards the oxidation process, thereby controlling sludge formation and maintaining the cleanliness of equipment.

For procurement managers and R&D scientists in the lubricant industry, sourcing a reliable supplier is as important as the product itself. When looking to buy Dioctyldiphenylamine, consider factors like product purity, consistent supply, and competitive pricing. Partnering with a reputable manufacturer and supplier, particularly one with a strong presence in regions like China, can provide a significant advantage. This ensures not only a steady supply of high-quality raw materials but also cost efficiencies that can be passed on to your customers.

Beyond lubricants, Dioctyldiphenylamine also finds critical applications in the rubber industry, protecting materials like natural rubber (NR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), and nitrile rubber (NBR) from heat, oxidation, and flex-cracking. Its ability to reduce the plasticity of unvulcanized CR and improve the stability of semi-finished articles during calendering further highlights its versatility.

When specifying antioxidants for your formulations, always request technical data sheets and Certificates of Analysis (COA) to verify product quality and specifications. Understanding the CAS number (101-67-7) is key to identifying the correct compound. For those seeking to purchase this essential chemical, exploring options from established suppliers will lead to the most robust and cost-effective solutions. Ensure you partner with a supplier who understands your needs and can provide the technical support necessary for optimal formulation.
