In the competitive landscape of material science and manufacturing, ensuring the longevity and consistent performance of polymers is paramount. Oxidative degradation, exacerbated by heat and processing, can severely compromise material integrity, leading to discoloration, loss of mechanical properties, and ultimately, product failure. This is where high-performance antioxidants, such as Bis[4-(2-phenyl-2-propyl)phenyl]amine (commonly known as Antioxidant 445), play a crucial role. As a key chemical intermediate, understanding its function and sourcing it from reputable suppliers is vital for procurement managers and R&D scientists alike.

Antioxidant 445, identified by its CAS number 10081-67-1, is a highly effective, non-discoloring aromatic amine antioxidant. Its primary function is to provide long-term heat stability to a wide array of materials, including polyolefins (like polyethylene and polypropylene), styrenic polymers, polyamides, and various elastomers. Manufacturers in China and globally rely on this compound to protect their products during critical processing stages, such as extrusion and injection molding, as well as during long-term storage and use.

One of the significant advantages of Antioxidant 445 is its low volatility. This means it remains within the polymer matrix even at elevated processing temperatures, offering continuous protection without significant loss. Furthermore, its low addition levels translate into cost-effectiveness for buyers, allowing them to achieve optimal stabilization without substantially increasing material costs. For those seeking to buy this essential chemical, understanding the benefits of sourcing from a qualified manufacturer is key to ensuring product purity and reliable supply.

The efficacy of Antioxidant 445 is further amplified by its synergistic capabilities. It works exceptionally well when combined with other primary antioxidants, such as phenolics, and auxiliary antioxidants like phosphites. This synergy allows formulators to create tailored stabilization packages that address specific degradation pathways and enhance overall product durability. For research scientists and product formulators, identifying the right combination of antioxidants is a critical step in developing high-performance materials.

Applications for Antioxidant 445 are diverse. It is extensively used in rubber compounding, providing excellent protection against thermal aging for synthetic rubbers like EPDM, NBR, and CR. In the plastics industry, it serves as a crucial heat stabilizer in masterbatches, adhesives, and wire & cable jacketing, particularly for colored applications where non-discoloration is a must. The ability to maintain material properties and prevent degradation makes it a go-to solution for chemical manufacturers and industrial consumers.

When evaluating suppliers for Antioxidant 445, prioritize those who can offer consistent quality, competitive pricing, and reliable delivery. As a leading supplier, NINGBO INNO PHARMCHEM CO.,LTD. ensures that procurement managers have access to this high-performance antioxidant, backed by technical expertise and a commitment to customer satisfaction. Investing in a quality antioxidant like 445 is an investment in the longevity and performance of your final products.
