Antioxidant 168
Antioxidant 168 belongs to the group of phosphite antioxidant and it has excellent performance. It has high extration resistance, is stable to hydrolysis, and can increase the light stability. Antioxidant 168 can be used together with different phenolic antioxidants. By using together with hindered amine antioxidants 1010 and 1076, it has good synergistic effect, and also improve polymer materials’ stability during thermal processing. In addition, there are more kinds of formulations compounded with phenolic antioxidants, and they are largely applied in polyolefins (such as polyethylene, polypropylene) and polyamides, olefin copolymers, PS resins, polycarbonates, engineering plastics, PVC, rubber, ABS resin, petroleum products, and other polymer materials
