In the chemical industry, specialized additives play a crucial role in enhancing the performance, durability, and longevity of materials. Among these, antioxidants are vital for protecting polymers from degradation. Ningbo Inno Pharmchem Co., Ltd. is pleased to offer a detailed overview of Antioxidant 616, scientifically known as Poly(dicyclopentadiene-co-p-cresol) and identified by CAS number 68610-51-5. This compound stands out as a high-performance polymeric phenolic antioxidant with a broad spectrum of industrial applications.

Antioxidant 616 is characterized by its polymeric structure, which contributes to its low volatility and minimal migration tendencies. This means that once incorporated into a polymer matrix, it remains effectively in place, providing sustained protection against oxidative damage throughout the material's lifecycle. Chemically, it is a sterically hindered phenol, a class of compounds renowned for their potent free radical scavenging capabilities. Its physical form is typically a white to off-white powder, making it easy to handle and incorporate into various manufacturing processes.

The key advantages of Antioxidant 616 stem from its multifaceted protective properties. It is non-staining and non-discoloring, which is a critical feature for applications involving light-colored or transparent materials, such as white rubber goods, clear plastics, and latex products. It offers excellent thermal stability, resisting decomposition at elevated processing temperatures, and demonstrates remarkable resistance to extraction by solvents. This ensures that the antioxidant's protective function is not compromised during product use or cleaning.

The applications of CAS 68610-51-5 are diverse and impactful. In the rubber industry, it is essential for protecting natural rubber, synthetic rubbers (SBR, NBR, BR), and thermoplastic elastomers (SBS, SIS) from premature aging, cracking, and loss of elasticity. It is also a standard antioxidant for various latex products, including gloves, condoms, and foam. In the plastics sector, it provides critical stabilization for styrene copolymers like ABS and MBS, as well as polyolefins, preventing degradation during processing and end-use. Its utility also extends to adhesives, lubricants, and coatings, where it enhances long-term performance.
