Antioxidant 802 is a phenolic secondary antioxidant used to improve long-term thermal stability (LTTS) in polymers. This compound is based on Dioctadecyl 3,3'-Thiodipropionate and plays an effective role in preventing thermal and oxidative degradation during processing and use.

It functions as a general thermal stabilizer, used alongside primary phenolic antioxidants and UV absorbers, and significantly enhances the chemical stability of polymers through a synergistic effect.

Properties of Antioxidant 802:

·         Thioester structure with high antioxidant performance

·         High melting point and low volatility

·         Resistance to heat- and oxygen-induced degradation

·         Approved for use in food contact applications

Applications:

·         Polymers requiring long-term thermal stability

·         Polyethylene (PE) power cables

·         XLPE (cross-linked polyethylene) cables

·         HDPE pipes

·         Polypropylene (PP)

·         Polyolefins used in automotive engines

·         Styrene homopolymers and copolymers such as PS and ABS

It is also used as an antioxidant additive in lubricating oils.
