* Antioxidant YD-136 is carbon free radical scavenger and efficiently trap radicals and play an important role for stabilization of polypropylene(PP) in the processing. * Compared with traditional Phenolic and phosphite antioxidants, YD-136 is of lower dosage and higher antioxidant performance. * It performs as a better synergist with phenolic antioxidant YD-1010 and Phosphite Ester Antioxidant YD-168 * Antioxidant YD-136 is particular effect for extrusion processing of Polypropylene at high temperature in extrusion equipment. It could effectively anti-yellowing and protect the material by trapping the carbon and alkyl radical that easily formed in hypoxic condition |
