The modern polymer industry relies heavily on specialized additives to enhance material properties and ensure product longevity. NINGBO INNO PHARMCHEM CO.,LTD. offers a versatile solution in the form of Antioxidant 245 (CAS 36443-68-2), a primary phenolic antioxidant that provides comprehensive protection across a broad spectrum of polymers. Its effectiveness stems from its ability to combat thermo-oxidative degradation, coupled with beneficial processing characteristics.

Antioxidant 245 is a high-performance sterically hindered phenolic antioxidant, making it an excellent choice for safeguarding polymers during both manufacturing and end-use applications. It effectively intercepts the free radical chain reactions responsible for degrading polymer structures when exposed to heat and oxygen. This protection is critical for materials used in demanding environments or subjected to rigorous processing conditions. Its application spans widely used polymers such as styrenics (including HIPS and ABS), synthetic rubbers, engineering plastics like POM, PA, and polyesters, as well as polyurethanes.

Beyond its primary antioxidant function, Antioxidant 245 serves other vital roles. It acts as a chain stopper in the manufacturing of PVC and ABS, contributing to better control over molecular weight and polymer consistency. For flexible PVC formulations, it is particularly noted for its efficacy in reducing 'fish eyes,' those common surface defects that detract from appearance and can compromise performance. This dual functionality enhances its value proposition for manufacturers.

The inherent properties of Antioxidant 245, such as its low volatility and good color stability, are significant advantages. Low volatility ensures that the additive remains present in the polymer matrix during high-temperature processing, thereby providing continuous protection. Good color stability means it does not impart unwanted coloration to the final product, preserving its intended aesthetics. Furthermore, its resistance to extraction ensures that the protective benefits are not easily lost through contact with other materials or the environment.

For industries seeking to enhance the durability and performance of their polymer products, incorporating Antioxidant 245 is a strategic decision. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted supplier for this essential additive, offering high-quality materials and technical support to help clients optimize their formulations. Whether aiming for improved thermal stability, better processing, or enhanced product appearance, Antioxidant 245 provides a robust and versatile solution. To purchase Antioxidant 245 and explore its extensive benefits, engaging with NINGBO INNO PHARMCHEM CO.,LTD. is the first step towards achieving superior polymer performance.
