Antioxidant PDDP


Antioxidant PDDP chemical name Phenyl Diisodecyl Phosphite, is an alkyl-aryl phosphite that can be used as a color and processing stabilizer in ABS, polycarbonate, polyurethane, coatings and PET fiber.



Antioxidant dppd is mainly used as a chelating agent for PVC. It can inhibit color change and increase oxidation resistance & light stability. It can improve color and weatherability when working with metal soap in PVC processing. In polyolefin, polystyrene, and polyamide, It can be used as a secondary stabilizer. Furthermore, it has ignition resistance and color stability in polyurethane foam.
