Songwon Secondary Antioxidants
Songwon Secondary Antioxidants are polymer stabilizer products designed to help protect materials from degradation during thermal processing, compounding, fabrication, and end-use applications. Secondary antioxidants help decompose hydroperoxides formed during oxidation, supporting better colour stability, melt flow, and consistent material performance.
In polymer formulations, secondary antioxidants such as phosphites and thioesters are commonly used together with primary antioxidants to deliver synergistic performance. This combination helps improve process stability, colour protection, long-term heat stability, and protection against oxidative degradation in substrates such as polyolefins, engineering plastics, elastomers, coatings, adhesives, and other industrial applications.
SONGNOX 1680 is a phosphite-based secondary antioxidant for plastics. It is used to support processing stability and colour protection during plastic processing, especially in applications requiring efficient and consistent antioxidant performance.
SONGNOX 6260 is a high performance phosphite-based secondary antioxidant for plastics. It helps provide melt flow protection and colour protection during thermal processing, and is often used with hindered phenol antioxidants for optimized stabilization performance.
SONGNOX 6280 is a phosphite-based secondary antioxidant consisting of SONGNOX 6260 and hydrotalcite. It is designed to provide colour stability, protection during compounding and fabrication, and good performance in polyolefins, elastomers, and engineering plastics.
SONGNOX 9228 is a phosphite-based secondary antioxidant for engineering plastics. It is suitable for applications requiring high process stability, protection against thermal degradation, and reliable stabilization performance in engineering polymer materials.
SONGNOX 9228T is a phosphite-based secondary antioxidant for polyolefins. It contains SONGNOX 9228 with triisopropanol amine, making it suitable for polyolefin applications that require consistent processing stability and colour protection.
SONGNOX CS 1680, SONGNOX CS 6260, and SONGNOX CS 9228 are secondary antioxidants for coatings that help improve formulation stability, oxidative protection, and coating performance during processing and end use. These products are suitable for coating systems that require good colour stability and material protection.
SONGNOX CS DSTDP and SONGNOX CS DTDTP are thioester or thioether-based secondary antioxidants for coatings and organic polymers. They help decompose and neutralize hydroperoxides and work synergistically with primary antioxidants to improve aging stability, light stability, and protection against oxidative degradation.
