Product features and uses
Antioxidant DHOP is a high molecular weight phosphite antioxidant with very high phosphorus content. As an antioxidant, DHOP has a strong ability to decompose hydrogen through oxides, and its hydroxyl value is about 20mg KOH/g. The combined use of hindered phenolic antioxidants and UV absorbers will produce a good synergistic effect.
The combination of antioxidant DHOP and hindered phenolic antioxidant can be widely used in polymer materials such as PVC and polyurethane.
