In the realm of material science, antioxidants are indispensable additives that preserve the integrity and extend the lifespan of polymers. Among these, Antioxidant 245 stands out as a high-performance primary antioxidant, widely recognized for its efficacy across a broad spectrum of polymer applications. NINGBO INNO PHARMCHEM CO.,LTD., a distinguished supplier in China, offers this vital chemical, enabling businesses to enhance the quality and durability of their products.

Antioxidant 245, chemically known as Triethylene glycol bis(3-tert-butyl-4-hydroxy-5-methylphenyl)propionate, is a sterically hindered phenolic antioxidant. Its molecular structure is specifically engineered to effectively scavenge free radicals, thereby preventing or significantly slowing down the process of thermo-oxidative degradation. This degradation pathway is a primary concern during polymer manufacturing, where materials are subjected to heat, and also during the end-use phase where polymers are exposed to environmental stresses. Its primary role is to protect the polymer from breaking down due to heat and oxygen exposure, making it a crucial component for achieving high performance sterically hindered phenolic antioxidant functionality.

Key properties that make Antioxidant 245 highly desirable include its low volatility, good color stability, and excellent extraction resistance. Low volatility ensures that the antioxidant remains effective even at elevated processing temperatures, without evaporating. Good color stability means it contributes minimally to discoloration, maintaining the aesthetic appeal of the final product. Furthermore, its extraction resistance ensures that the antioxidant stays within the polymer matrix, providing long-lasting protection, which is a key benefit in applications requiring extraction resistant antioxidant properties.

The application range for Antioxidant 245 is extensive. It is highly effective in stabilizing a wide variety of polymers, including styrenics, synthetic rubbers, polyurethanes, polyamides, polyesters, MBS, and PVC. In PVC and ABS production, it serves as a critical chain stopper, helping to control molecular weight and improve processing. For flex-PVC, it also contributes to reducing 'fish eyes,' a common surface defect. Its utility is further enhanced by its ability to work synergistically with other stabilizers like benzotriazoles and HALS, providing comprehensive thermal and light stabilization. This makes it an important consideration when looking for antioxidant for polyamides or polyurethanes.

By incorporating Antioxidant 245 into their formulations, manufacturers can achieve several key business advantages. These include improved product durability, extended service life, enhanced processing efficiency, and reduced material waste due to degradation.
