Dragonox® 245 is a highly effective asymmetric hindered phenol antioxidant with high antioxidant efficiency, low volatility, good oxidation resistance, and good coloring performance. It has a significant synergistic effect with auxiliary antioxidants (such as thioester, phosphite, etc.) and can be used with light stabilizers to give excellent weather resistance to products. This substance is mainly used during polymer processing and for long-term heat stabilization of hips, ABS, MBS, other styrene polymers, POM, PA, PUR, PVC, and thermoplastic polyester. It can be used as an effective chain terminator in the polymerization process of PVC and can be added to the monomers of polystyrene and PVC without affecting the polymerization reaction.
