In the demanding world of polymer manufacturing, ensuring the longevity and consistent performance of materials is paramount. Degradation, often caused by heat, light, and oxygen, can severely compromise the structural integrity and aesthetic appeal of finished products. This is where advanced additives like secondary antioxidants play a crucial role. As a leading manufacturer and supplier, we are committed to providing cutting-edge solutions to help you protect your polymer investments.

Secondary antioxidants, such as our high-performance phosphonite type (CAS: 119345-01-6), work by decomposing hydroperoxides, which are key intermediates in the oxidative degradation pathway of polymers. Unlike primary antioxidants that scavenge free radicals, secondary antioxidants act as peroxide decomposers. This dual-action approach, when combined with primary antioxidants, offers superior protection against both short-term processing degradation and long-term thermal aging. This synergy is vital for applications requiring high heat resistance and extended service life.

Our secondary antioxidant is particularly effective in a wide array of polymer systems, including polyolefins (like polypropylene and polyethylene), elastomers, and engineering plastics such as polycarbonate (PC), polyethylene terephthalate (PET), and polyamides (PA). Its excellent color stability during compounding and fabrication is a significant advantage for manufacturers aiming for aesthetically pleasing products. Furthermore, it serves as an efficient processing stabilizer, preventing discoloration and maintaining the melt flow properties of polymers under high-temperature conditions. This makes it an indispensable additive for industries ranging from automotive and electronics to packaging and textiles.

For businesses seeking to enhance their product offerings and gain a competitive edge, integrating a reliable secondary antioxidant is a strategic move. We understand the importance of sourcing high-quality materials. As a dedicated supplier based in China, we ensure that our clients receive not only premium products but also competitive pricing and dependable supply chain management. Whether you are formulating advanced adhesives, durable coatings, or high-performance plastic components, our antioxidant is designed to meet your most stringent requirements.
