In the world of polymer manufacturing, maintaining the integrity and extending the lifespan of plastic products is paramount. Degradation, primarily caused by oxidation, heat, and UV light, can significantly compromise a material's physical properties, leading to brittleness, discoloration, and ultimately, product failure. This is where antioxidants play a critical role. As a leading manufacturer and supplier of high-quality chemical additives, NINGBO INNO PHARMCHEM CO.,LTD. understands the vital importance of selecting the right antioxidant. In this blog post, we delve into the benefits of primary antioxidants, with a focus on Pentaerythritol Tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate), commonly known as Antioxidant 1010 (CAS 6683-19-8).

Understanding Oxidation and Polymer Degradation

Oxidation is a chemical process that involves the loss of electrons, often triggered by exposure to oxygen, heat, or light. In polymers, this process can initiate a chain reaction, breaking down long molecular chains and creating free radicals. These free radicals are highly reactive and can attack other polymer molecules, leading to a cascade of degradation. This results in a decline in mechanical strength, elasticity, and overall performance of the plastic material. This is a concern for any procurement manager looking for durable materials.

The Role of Primary Antioxidants

Primary antioxidants, such as hindered phenols, function by scavenging free radicals. They readily donate a hydrogen atom to the free radicals, neutralizing them and effectively terminating the oxidative chain reaction. This sacrificial role protects the polymer matrix from further damage. For manufacturers seeking to buy high-quality additives, understanding this mechanism is key to ensuring product stability. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of primary antioxidants, including Antioxidant 1010, to meet your needs.

Antioxidant 1010: A Superior Choice for Polymer Stabilization

Antioxidant 1010 (CAS 6683-19-8) is a highly effective, non-discoloring, primary antioxidant extensively used in the polymer industry. Its molecular structure, featuring four sterically hindered phenolic groups attached to a pentaerythritol core, provides excellent performance. Key benefits include:

  • Excellent Thermal Stability: It provides long-term heat stability, protecting the physical properties of polymers during processing at high temperatures and throughout the product's service life. This is a critical factor for product formulation scientists.
  • Reduced Viscosity Change and Gel Formation: During polymer processing, high temperatures can lead to unwanted changes in melt viscosity and the formation of gels. Antioxidant 1010 effectively minimizes these issues, ensuring smoother manufacturing runs.
  • Synergistic Effects: It exhibits a synergistic effect when combined with secondary antioxidants, such as phosphites or thioethers. This means that the combination provides superior protection compared to either antioxidant used alone, offering a more comprehensive stabilization package.
  • Low Volatility: Its high molecular weight results in low volatility, meaning it is less likely to evaporate during high-temperature processing, ensuring its effectiveness is maintained within the polymer matrix.
