Antioxidant 1425 AO-1425 65140-91-2

It is an efficient and high-temperature resistant white powdery phenolic antioxidant with a melting point of ≥ 260 ℃. It has the advantages of low volatility, strong extraction resistance, and no discoloration, making it particularly suitable for photo thermal stability protection of materials such as polypropylene fiber, polyester (PET), nylon, etc. It can significantly inhibit oxidative degradation and reduce acetaldehyde production. It can also be used as an esterification catalyst in the synthesis of rosin esters, shortening reaction time and improving product thermal stability. Widely used in engineering plastics, synthetic fibers, and high-temperature processing systems to ensure long-term material performance.
