The quest for enhanced polymer performance and extended product life necessitates the strategic use of specialized additives. NINGBO INNO PHARMCHEM CO.,LTD. offers Antioxidant 445, a key player in the field of polymer stabilization. This aromatic amine antioxidant, identified by CAS No. 10081-67-1, is renowned for its potent ability to act as a thermal stabilizer across a wide range of polymeric materials, including polyolefins, styrenics, polyamides, and elastomers. Its non-discoloring nature and low volatility make it an attractive choice for applications demanding both high performance and aesthetic appeal.

One of the primary applications for Antioxidant 445 is in the stabilization of polyolefins like polyethylene (PE) and polypropylene (PP). During the high-temperature processes involved in manufacturing plastic films, pipes, and molded articles, polymers are exposed to conditions that can initiate oxidative degradation. Antioxidant 445 effectively intercepts these degradation pathways, preserving the melt flow index and preventing embrittlement, thereby ensuring the mechanical integrity and longevity of the final products. Its effectiveness in these materials highlights its role as a vital thermal stabilizer for polyolefins.

In the rubber industry, Antioxidant 445 contributes significantly to preventing degradation caused by heat, oxygen, and mechanical stress. This is crucial for rubber components used in automotive parts, industrial hoses, and seals, where durability and resistance to aging are paramount. The non-discoloring characteristic of this antioxidant is particularly beneficial for colored rubber products, allowing for vibrant hues without compromising protective capabilities. The synergy of antioxidants in plastics and rubber is well-documented, and Antioxidant 445 plays a key role in these synergistic blends, often working in concert with phenolic and phosphite antioxidants to provide a comprehensive protection system.

Beyond polyolefins and rubber, Antioxidant 445 finds application in various other sectors. It is utilized in styrenic polymers, such as polystyrene (PS) and acrylonitrile butadiene styrene (ABS), to enhance their thermal stability and resistance to yellowing. In the realm of adhesives, especially hot melt adhesives, it helps maintain stability during application and after solidification, ensuring bond strength and longevity. Lubricants also benefit from its inclusion, as it protects base oils and additives from oxidative breakdown, thereby maintaining lubricating properties and extending the service interval. The benefits of a non-discoloring aromatic amine antioxidant are multifaceted, impacting processing efficiency, product aesthetics, and long-term performance across numerous industrial applications. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality additives like Antioxidant 445 to meet the evolving needs of the global market.
