Polymers are susceptible to degradation from various environmental factors, most notably oxidation. This process, driven by heat, light, and mechanical stress, can significantly shorten the lifespan and compromise the performance of plastic and rubber products. Understanding how to combat this degradation is key to manufacturing durable goods. This is where antioxidants play a crucial role.

Antioxidants are chemical additives that protect polymers by interrupting the degradation processes. They are broadly categorized into primary and secondary types. Primary antioxidants, often hindered phenols or aromatic amines, act as free radical scavengers. They neutralize the harmful free radicals that initiate and propagate oxidation chains. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of such stabilizers that help maintain polymer integrity.

Secondary antioxidants, also known as hydroperoxide decomposers, work by reacting with hydroperoxides, which are byproducts of oxidation. These compounds convert hydroperoxides into stable, non-radical products, thereby preventing further degradation. Phosphites and thioesters are common examples of secondary antioxidants, and they are particularly effective when used in synergistic combinations with primary antioxidants. This combined approach offers a more robust defense against oxidation.

Antioxidant 565, a high molecular weight, non-staining, and multifunctional antioxidant, exemplifies the power of such additives. Its strong free radical scavenging activity and metal chelating properties make it a highly effective solution for a wide array of applications, from elastomers to adhesives and sealants. When you need to buy or purchase high-quality polymer heat stabilizers, considering products like Antioxidant 565 from NINGBO INNO PHARMCHEM CO.,LTD. is essential for ensuring optimal product performance and longevity.

By incorporating advanced antioxidants into their formulations, manufacturers can significantly improve the resistance of their products to aging, ensuring they meet the demanding performance requirements across various industries. The availability of reliable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. ensures that these crucial components are accessible for your production needs.
