For plastics manufacturers, achieving consistent product quality hinges on robust processing stability. This involves protecting polymers from degradation during high-temperature molding, extrusion, and other fabrication processes. Oxidation is a primary culprit, leading to chain scission, cross-linking, and ultimately, a decline in mechanical properties and aesthetic appeal. Identifying the right antioxidant is therefore crucial. From our position as a leading chemical supplier in China, we focus on providing solutions like AO-80, a high-performance antioxidant designed to meet these challenges.

AO-80 (CAS 90498-90-1) is a highly effective hindered phenolic antioxidant known for its ability to significantly improve processing stability across a wide range of polymers. Its low volatility ensures it remains within the polymer matrix during demanding processing cycles, providing continuous protection. Unlike some antioxidants, AO-80 is non-discoloring and exhibits excellent resistance to gas fading, meaning it won't negatively impact the final color of your products. This makes it an invaluable additive for applications where aesthetics are as critical as mechanical performance.

Its efficacy has been proven in diverse polymer systems. For polyolefins such as PP, HDPE, and LLDPE, AO-80 helps maintain molecular weight and prevent yellowing during extrusion and molding. In styrenic polymers like ABS and HIPS, it safeguards against thermal-oxidative degradation, preserving impact strength and surface finish. Furthermore, it is an excellent choice for engineering plastics like PBT, POM, and PA, which are often processed at higher temperatures. When you purchase AO-80 from a reputable supplier in China, you gain a partner committed to quality and reliability. Our team can provide detailed technical support and competitive pricing to ensure your manufacturing processes are optimized.

The recommended usage level for AO-80 typically ranges from 0.1% to 0.5% by weight, depending on the polymer type and processing conditions. Its synergistic effect when combined with secondary antioxidants further enhances its performance, offering comprehensive protection. If you are searching for a dependable manufacturer and supplier of AO-80 to boost your product’s processing stability, explore our offerings. We are dedicated to delivering high-quality chemical additives that enhance your manufacturing output and product value.
