Application Description A polymer type phosphite antioxidant with high molecular weight and high phosphorus content, mainly used to partially replace organic tin stabilizers in non-toxic products such as PVC materials, films, and sheets. It can also be used as an oxygen heat stabilizer in PE, PP, ABS, SBS, and as a co antioxidant. It has a strong ability to decompose hydrogen through oxides. It has a good synergistic effect with main antioxidants such as "1010", which can improve the antioxidant effect and reduce product costs. It can be used in polymer materials such as PVC and polyurethane when compounded with hindered phenolic antioxidants. Suggested dosage: 0.1~2.0%
