| Application | AO 412S is a low-volatility, high-molecular-weight organosulfur-containing antioxidant, specifically developed for polyolefins and engineering plastics. It is particularly suited for products demanding high-temperature resistance and long-term aging performance. When compounded with hindered phenolic primary antioxidants, AO 412S delivers superior stability compared to traditional thioether antioxidants (e.g., DLTDP, DSTDP). Boasting excellent anti-extraction and anti-migration properties, this product is ideal for polyolefin end products prone to water impregnation or used under harsh climatic conditions, and also holds significant application value in polymer fibers. AO 412S is suitable for long-term aging resistance applications in engineering plastics such as PP, PE, ABS, PS, PA, and PC. It is especially well-suited for low-volatility thin-walled products, thin-film materials, and polymer fibers. Its outstanding anti-extraction and anti-migration capabilities make it particularly applicable to high-temperature plumbing systems, washing machines, and dishwashers. | ||
