Thioether Antioxidant

Secondary antioxidants, such as phosphites and thioethers, decompose hydroperoxides into non-radical, non-reactive, and thermally stable products. Therefore, auxiliary antioxidants are also called hydroperoxide decomposers. Phosphites and thioethers antioxidants are widely used hydroperoxide decomposers. Phosphites are most effective at the high temperatures of melt processing operations, while thioethers work best in the solid phase at long-term use temperatures. Secondary antioxidants are used together with primary antioxidants to increase the stability of polymers.

Although thiosynergists do not improve the melt stability of polymers during polymer processing, they are very effective for long-term heat aging applications. Sulfur-based hydroperoxide decomposers are mainly used in combination with hindered phenolic antioxidants.

For more than 30 years, TINTOLL has been committed to providing innovative high-performance light stabilizers and primary and secondary antioxidant solutions to meet the growing and changing technical needs of the global plastics market.

TINTOLL's primary and secondary antioxidants play an important role in inhibiting and delaying the oxidation and degradation of polymeric materials. TINTOLL is available in a variety of physical forms as well as standard and custom blends. The choice of primary antioxidant and secondary antioxidant in polymer depends on factors such as compatibility, color and thermal stability, volatility and stabilizer efficiency.
