Antioxidants play a crucial role in various industries, especially in the polymer and plastic sectors, where they help to prevent the degradation of materials caused by oxidation. Among the numerous antioxidants available in the market, Antioxidant 1076 stands out for its excellent performance and wide - ranging applications. As a reliable Antioxidant 1076 supplier, I am delighted to share detailed information about its chemical formula and related aspects.
Chemical Formula of Antioxidant 1076
The chemical name of Antioxidant 1076 is octadecyl 3 - (3,5 - di - tert - butyl - 4 - hydroxyphenyl)propionate. Its chemical formula is (C_{35}H_{62}O_3). This formula reveals a complex organic structure that is the key to its antioxidant properties.
The molecule consists of a long - chain alkyl group (octadecyl, (C_{18}H_{37})) and a substituted phenolic group. The phenolic group, which contains two tert - butyl groups at the 3 and 5 positions and a hydroxyl group at the 4 position, is the active site for scavenging free radicals. The long alkyl chain provides good compatibility with polymers, allowing the antioxidant to disperse evenly in the polymer matrix.
How Antioxidant 1076 Works
Oxidation is a chemical reaction that involves the transfer of electrons from a substance to an oxidizing agent. In polymers, oxidation can lead to a variety of problems, such as discoloration, loss of mechanical properties, and reduced service life. Free radicals are highly reactive species that are generated during the oxidation process. Antioxidant 1076 acts as a free - radical scavenger.
The hydroxyl group on the phenolic ring of Antioxidant 1076 can donate a hydrogen atom to a free radical. This reaction stabilizes the free radical and forms a relatively stable phenoxy radical. The phenoxy radical is less reactive and can further react with other free radicals to terminate the oxidation chain reaction. In this way, Antioxidant 1076 effectively inhibits the oxidation of polymers and protects them from degradation.
Advantages of Antioxidant 1076
- Excellent Compatibility: Due to its long alkyl chain, Antioxidant 1076 has good compatibility with a wide range of polymers, including polyethylene (PE), polypropylene (PP), polystyrene (PS), and ABS resins. This ensures that it can be easily incorporated into polymer formulations without causing phase separation or other compatibility issues.
- Low Volatility: The relatively high molecular weight of Antioxidant 1076 results in low volatility. This is important during high - temperature processing of polymers, as it reduces the loss of the antioxidant through evaporation and ensures long - term protection.
- Good Color Stability: Antioxidant 1076 helps to maintain the color of polymers during processing and use. It prevents the formation of yellowing and other color changes caused by oxidation, which is particularly important for applications where color stability is critical, such as in the production of white or light - colored plastic products.
Comparison with Other Antioxidants
There are many other antioxidants in the market, such as Antioxidant B215, Antioxidant 1035, and Antioxidant 1010.
- Antioxidant B215: It is a blend of a primary antioxidant (usually a phenolic antioxidant) and a secondary antioxidant (such as a phosphite antioxidant). While Antioxidant B215 provides a synergistic effect for better antioxidant performance, Antioxidant 1076 is a single - component antioxidant that is more straightforward to use and has good performance on its own in many applications.
- Antioxidant 1035: It is also a phenolic antioxidant, but its chemical structure is different from that of Antioxidant 1076. Antioxidant 1035 has a different alkyl chain length and substitution pattern on the phenolic ring, which may result in different compatibility and antioxidant performance characteristics.
- Antioxidant 1010: It is a hindered phenolic antioxidant with a higher molecular weight and multiple active phenolic groups. Antioxidant 1010 generally provides long - term protection, but it may have a higher cost. Antioxidant 1076, on the other hand, offers a good balance between performance and cost, making it a popular choice for many applications.
Applications of Antioxidant 1076
- Plastic Industry: Antioxidant 1076 is widely used in the production of various plastics, such as PE, PP, and PS. In PE and PP pipes, it helps to maintain the mechanical strength and prevent cracking and embrittlement over time. In PS packaging materials, it ensures the transparency and color stability of the products.
- Rubber Industry: It can also be used in the rubber industry to improve the aging resistance of rubber products. By adding Antioxidant 1076, rubber products such as tires, seals, and gaskets can have a longer service life and better performance under various environmental conditions.
- Lubricant Industry: In lubricants, Antioxidant 1076 helps to prevent the oxidation of the base oil, which can lead to the formation of sludge and varnish. This improves the lubricating performance and extends the service life of the lubricant.
