In the demanding world of material science and manufacturing, ensuring the longevity and performance of polymers is paramount. Oxidative degradation, driven by heat, light, and oxygen, can severely compromise the structural integrity and aesthetic appeal of plastic products. This is where high-quality antioxidants play a crucial role. Among these essential additives, Antioxidant 245 stands out as a highly effective solution for a wide array of polymer applications.

Antioxidant 245, with its CAS number 36443-68-2, is a sterically hindered phenolic antioxidant. Its unique chemical structure provides excellent protection against thermo-oxidative degradation. This means that during manufacturing processes, such as extrusion and molding, and throughout the product's service life, Antioxidant 245 works diligently to prevent the chain reactions that lead to material breakdown. Manufacturers seeking to buy this vital component can rely on its consistent quality and effectiveness.

The benefits of incorporating Antioxidant 245 into your formulations are numerous. It is characterized by low volatility, meaning it remains within the polymer matrix even at elevated temperatures, providing continuous protection. Furthermore, its low odor profile is advantageous for applications where scent is a concern. Crucially, it exhibits high extraction resistance, ensuring that the antioxidant doesn't leach out when the polymer comes into contact with solvents or other chemicals, a critical factor for many industrial applications.

The versatility of Antioxidant 245 is one of its most significant advantages. It is particularly effective in styrene polymers, including High Impact Polystyrene (HIPS), Acrylonitrile Butadiene Styrene (ABS), Styrene-Butadiene Rubber (SBR) lattices, and Methyl Methacrylate-Butadiene-Styrene (MBS) resins. Beyond styrene-based polymers, it also finds extensive use in engineering plastics such as Polyoxymethylene (POM) and Polyamide (PA), as well as in various polyurethane applications like Thermoplastic Polyurethane (TPU) and spandex. For those looking to purchase these high-performance polymers, ensuring they contain effective antioxidants like 245 is key.

An additional key function of Antioxidant 245 is its role as a chain terminator in PVC polymerization. This property helps control the polymerization process, leading to more consistent product quality and improved material properties. This makes it an indispensable additive for PVC manufacturers seeking to optimize their production cycles and final product characteristics.
