Antioxidant 168 is a phosphite antioxidant supplied in the form of a white powder and is widely used in the plastics and polymer industries. This product offers excellent thermal stability, low volatility, and outstanding hydrolysis resistance. It is readily soluble in organic solvents such as benzene, chloroform, and cyclohexane. Due to its low toxicity and effective performance, Antioxidant 168 is considered one of the most important additives used in polymer processing.

Antioxidant 168 protects polymers against oxidation and thermal degradation during processing, helping to maintain material quality and stability. It prevents discoloration, quality deterioration, and the loss of physical properties in plastics, thereby extending the service life of polymer products. It is also highly effective in decomposing hydroperoxides generated during thermal processing.

This product is widely used in polyethylene (PE), polypropylene (PP), polyamides, polycarbonates, PVC, ABS, polystyrene (PS) resins, and other engineering plastics. In addition, it is used in the production of adhesives, natural and synthetic resins, rubber compounds, and certain petroleum-based products, improving their resistance to heat and oxidation while enhancing long-term stability.
