Application
Diphenyl Isodecyl Phosphite is primarily employed as a secondary antioxidant and heat stabilizer in polymer systems, where it effectively scavenges free radicals and decomposes hydroperoxides to prolong material lifespan. It is commonly used in conjunction with primary antioxidants to enhance the thermal and oxidative stability of polyolefins, PVC, and synthetic rubbers. Additionally, this phosphite ester finds utility in lubricant formulations to prevent viscosity breakdown and deposit formation under high-temperature conditions. Its compatibility with a broad range of additives makes it a versatile choice for advanced material development.
