In the critical field of polymer stabilization, selecting the appropriate antioxidant is paramount to ensuring material longevity and performance. Among the most widely used are hindered phenolic antioxidants, with Antioxidant 1076 and Antioxidant 1010 being prominent examples. Both are highly effective at preventing oxidative degradation, yet subtle differences in their properties and applications can guide formulators in making the optimal choice. NINGBO INNO PHARMCHEM CO.,LTD. offers both these vital additives and is committed to helping clients navigate these distinctions.

Both Antioxidant 1076 (CAS: 2082-79-3) and Antioxidant 1010 (CAS: 6683-19-8) belong to the class of hindered phenolic antioxidants. Their primary mechanism of action involves donating a hydrogen atom from their phenolic hydroxyl group to free radicals, thereby terminating the chain reaction of oxidation. From a product form perspective, both typically appear as white powders, making them easy to handle and incorporate into various polymer systems. The general consensus from many antioxidant 1076 manufacturers and suppliers, including NINGBO INNO PHARMCHEM CO.,LTD., is that they offer substantial protection against thermal oxidative degradation.

However, key differences emerge when examining their molecular structure, molecular weight, and melting points. Antioxidant 1076 has a molecular weight of approximately 531 g/mol and a melting point typically in the range of 50-55°C. In contrast, Antioxidant 1010 possesses a significantly higher molecular weight, around 1178 g/mol, and a higher melting point, generally between 110-125°C. These distinctions have practical implications for their use. The higher melting point of Antioxidant 1010 makes it more suitable for applications requiring higher processing temperatures or where long-term thermal stability is even more critical.

The difference in molecular weight and melting point also influences their volatility and migration characteristics. Antioxidant 1010, with its larger molecular size and higher melting point, generally exhibits lower volatility and reduced migration compared to Antioxidant 1076. This can be advantageous in applications where the antioxidant might be exposed to extraction by liquids or where maintaining the additive within the polymer matrix over extremely long periods is crucial. However, Antioxidant 1076 still offers very good low volatility and extraction resistance, making it highly effective for a broad range of standard applications.

When considering the antioxidant 1076 vs 1010 comparison, the choice often comes down to specific processing conditions, required service life, and regulatory compliance. Antioxidant 1076's properties often make it a cost-effective solution for many general-purpose polymer applications where its performance characteristics are perfectly adequate. Its ease of dispersion and good compatibility also contribute to its popularity. NINGBO INNO PHARMCHEM CO.,LTD. provides both to ensure formulators have access to the best tools for their specific needs, understanding that the optimal antioxidant 1076 price and performance must be balanced with application demands.

In summary, while both Antioxidant 1076 and 1010 are excellent hindered phenolic antioxidants, Antioxidant 1010 generally offers superior performance in extreme conditions due to its higher molecular weight and melting point. Nevertheless, Antioxidant 1076 remains a highly effective and often more economical choice for a vast array of applications.
