In the pursuit of creating durable and long-lasting materials, the role of effective antioxidants cannot be overstated. Tris(2,4-di-tert-butylphenyl) phosphite, often referred to by its designation Antioxidant 168, is a cornerstone additive that significantly contributes to material longevity across numerous industries. Its primary function as a secondary antioxidant is to protect polymers and other organic substrates from the detrimental effects of oxidation and thermal degradation.

Antioxidant 168 operates by efficiently neutralizing hydroperoxides, which are transient species formed during the autoxidation of materials. By intervening in this process, it prevents the formation of free radicals that would otherwise propagate a chain reaction, leading to material breakdown. This crucial action ensures that polymers maintain their structural integrity and mechanical properties even when subjected to heat, stress, and exposure to oxygen. This makes it an ideal candidate for applications requiring high thermal stability.

The benefits extend beyond simple protection. Tris(2,4-di-tert-butylphenyl) phosphite boasts low volatility, meaning it remains effective within the material matrix without significant loss during processing or use. This low volatility, combined with its high heat stability, ensures consistent and reliable performance over time. Furthermore, it exhibits a powerful synergistic effect when used in conjunction with primary antioxidants, such as hindered phenolic antioxidants. This combined approach offers superior protection against degradation, significantly extending the service life of the final product.

The versatility of Tris(2,4-di-tert-butylphenyl) phosphite is evident in its broad compatibility with a wide spectrum of polymers, including polyolefins, ABS, PVC, and many others. This adaptability makes it a valuable additive for manufacturers in the plastics, rubber, coatings, and adhesives industries, where material performance and longevity are critical.
