Polymers, widely used in countless applications, are inherently susceptible to degradation when exposed to environmental factors such as heat, light, and oxygen. This degradation process involves the formation of free radicals, which can lead to chain scission, cross-linking, and ultimately compromise the material's physical properties, appearance, and service life. To effectively combat this issue, antioxidants are introduced during polymer processing and manufacturing.

Among the most critical additives in the polymer industry is Antioxidant 1076, chemically known as Octadecyl-3-(3',5'-di-t-butyl-4'-hydroxyphenyl)propionate. Identified by its CAS No. 2082-79-3, this hindered phenolic antioxidant is a primary stabilizer renowned for its effectiveness in preventing thermal and oxidative degradation. As a cornerstone additive, it plays a vital role in extending the durability and performance of polymeric materials.

NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-quality chemical raw materials, including high-purity Antioxidant 1076. This essential product is typically supplied as a fine white powder, making it easy to handle and incorporate into various polymer matrices. Key quality specifications for Antioxidant 1076 include a high purity level, typically meeting or exceeding 98.0%. Its melting point falls within the range of 50.0 to 55.0ºC. Furthermore, low impurity levels, such as minimal ash content (≤0.10%) and low volatile matter (≤0.20%), ensure that the additive does not introduce undesirable side effects into the final product. High light transmittance values at 425nm (≥97.0%) and 500nm (≥98.0%) indicate excellent clarity and minimal impact on the color of transparent or lightly colored polymers.

The primary function of Antioxidant 1076 is to act as a free radical scavenger. During the initial stages of polymer oxidation, unstable peroxy radicals are formed. Antioxidant 1076 reacts with these radicals, terminating the chain reaction and preventing further degradation. This mechanism provides excellent long-term heat stability, protecting the polymer during high-temperature processing steps like extrusion, injection molding, and blow molding, as well as throughout the product's service life in elevated temperature environments. The benefits are tangible: reduced yellowing or discoloration, preservation of mechanical strength and flexibility, and overall extension of product lifespan.

One of the significant advantages of Antioxidant 1076 is its low volatility. This property means that the additive remains within the polymer matrix even at high processing temperatures, reducing fuming and minimizing loss over time. Its good resistance to extraction by water and other solvents also makes it suitable for applications where the finished article may come into contact with liquids. Furthermore, Antioxidant 1076 is often used in combination with secondary antioxidants, such as phosphites, to achieve synergistic effects. While primary antioxidants like 1076 scavenge peroxy radicals, secondary antioxidants decompose hydroperoxides into non-radical products, offering a more comprehensive stabilization system.

The versatility of Antioxidant 1076 is reflected in its broad range of applications. It is an indispensable additive for polyolefins, including polyethylene (PE) and polypropylene (PP), widely used in films, fibers, and molded parts. It is also highly effective in styrenic polymers such as polystyrene (PS) and ABS resins, improving their thermal resistance. Other key application areas include various engineering plastics, elastomers (like rubber), flexible and rigid PVC formulations, PMMA, polyurethanes, adhesives, and coatings. The recommended addition level for Antioxidant 1076 is typically between 0.05% and 1.0%, though the optimal concentration depends on the specific polymer, processing conditions, and the required performance criteria, often determined through testing.
