Application

Antioxidant PDP is a secondary antioxidant for organic polymers. It is an effective liquid polymeric phosphite for many types of diverse polymer applications including PVC, ABS, Polyurethanes, Polycarbonates and coatings to provide improved color and heat stability during processing and in the end application. It can be used in rigid and flexible PVC applications as a secondary stabilizer and chelating agent to give brighter, more consistent colors and improve the heat stability of PVC. It can be also used in polymers where regulatory approval for food contact is not required. Typical use levels range from 0.2- 1.0% for most applications.
