Antioxidant 802 is a phenolic co-antioxidant used to enhance long-term thermal stability (LTTS) in polymers. This compound is designed based on Dioctadecyl 3,3'-Thiodipropionate and plays an effective role in preventing thermal and oxidative degradation during the production and consumption process.

It is used as a general thermal stabilizer, along with primary phenolic antioxidants and UV absorbers, and significantly improves the chemical stability of the polymer through a synergistic effect.

Antioxidant 802 Features

•        Thioester structure with high antioxidant performance
