For any organization involved in polymer manufacturing, understanding the critical properties of additives like Antioxidant 245 (CAS: 36443-68-2) is fundamental to achieving optimal product performance and stability. As a chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD. highlights the distinctive features of this sterically hindered phenolic antioxidant, emphasizing its value to formulators and procurement managers worldwide. Its effectiveness in preventing degradation makes it a crucial component in many plastic and rubber formulations.

The primary advantage of Antioxidant 245 lies in its robust protective capabilities against thermo-oxidative degradation. This process, accelerated by heat and oxygen, can lead to irreversible damage in polymers, manifesting as brittleness, discoloration, and loss of mechanical strength. Antioxidant 245 effectively interrupts these degradation pathways by scavenging free radicals. Its chemical composition, Triethylene glycol bis(3-tert-butyl-4-hydroxy-5-methylphenyl)propionate, contributes to its high molecular weight and, consequently, its low volatility. This low volatility is a significant asset, ensuring that the antioxidant remains within the polymer matrix during high-temperature processing and throughout the product's lifespan, providing enduring protection.

Another critical feature that makes Antioxidant 245 a preferred choice for manufacturers is its high extraction resistance. This property is vital in applications where the polymer may come into contact with solvents, oils, or other liquids. The resistance ensures that the protective antioxidant is not leached out, maintaining its efficacy over time. For procurement professionals looking to buy this additive, understanding this attribute is key to ensuring long-term product reliability and performance. Coupled with good color stability, it helps preserve the aesthetic qualities of the finished polymer products.

The versatility of Antioxidant 245 extends to its role as a chain stopper in polymerization processes, particularly for PVC and ABS. This function is critical for controlling molecular weight and preventing uncontrolled reactions, thereby enhancing the consistency and quality of the final polymer. Furthermore, its application in reducing fish-eye defects in flexible PVC improves the surface finish and clarity of films and sheets. The potential for synergistic effects when combined with other stabilizers, such as thioester antioxidants or UV absorbers, allows for the development of advanced, multi-functional additive systems. For those seeking to buy specialized chemical solutions, sourcing these materials from experienced manufacturers in China offers access to both expertise and competitive pricing.
