In the competitive landscape of plastic manufacturing, ensuring the longevity and performance of your products is paramount. One of the critical factors influencing this is the use of effective antioxidants. These additives play a vital role in preventing degradation caused by heat, light, and oxidation during processing and throughout the product's lifecycle. For manufacturers seeking reliable solutions, understanding the different types of antioxidants and their applications is key. We, as a dedicated supplier in China, aim to provide clarity on these essential chemical components.

Among the most effective are hindered phenolic antioxidants. These compounds function by scavenging free radicals, thereby interrupting the oxidation chain reaction. A prime example of such a high-performance additive is AO-80 (CAS 90498-90-1). As a prominent manufacturer and supplier of AO-80 in China, we’ve seen firsthand its exceptional capabilities. This high molecular weight antioxidant is particularly valued for its low volatility and excellent resistance to discoloration, especially when exposed to NOx gases, a common issue in certain environments.

AO-80 is highly recommended for a broad spectrum of polymers. For polyolefins like Polypropylene (PP), High-Density Polyethylene (HDPE), and Linear Low-Density Polyethylene (LLDPE), it offers superior processing stability and long-term heat stabilization. Similarly, in styrenic polymers such as Acrylonitrile Butadiene Styrene (ABS) and Polystyrene (PS), it significantly enhances durability. Furthermore, its utility extends to engineering plastics like Polybutylene Terephthalate (PBT), Polyoxymethylene (POM), Polycarbonate (PC), Polyamides (PA), and Polyurethanes (PU) and Nylon. The typical addition rate for AO-80 is between 0.1-0.5%, though this can vary based on the specific application and desired protection level. We are a trusted manufacturer and supplier ready to provide quotes and samples to help you evaluate its effectiveness for your needs.

The synergistic effect of AO-80 when paired with secondary antioxidants, such as thioethers, is also a significant advantage for achieving optimal long-term heat stability (LTHS). This makes it an excellent choice for applications subjected to severe processing conditions or high service temperatures. By choosing a reliable manufacturer and supplier like us, you ensure access to high-purity AO-80, competitive pricing, and a consistent supply chain.
