Features and Benefits:

TA-626 can increase the stability of polymer in blend, production and use, reduce polymer degradation on process and raise polymer gas and fading resistance. High-performance, low-input capacity can prepare a more efficient formula. It has higher phosphorus content than other equivalent phosphite antioxidants, and it can be used as a synergist of light stabilizer like benzene and benzotriazole.

Applications: TA-626 is a high performance solid organic phosphite antioxidant, and it can well protect the color of polymer, superior to other phosphite, and generally its not used alone. It is usually combined with phenolic based primary antioxidants like antioxidant TA-1010, and it can improve the thermal stability of polymer on process. The blends of TA-626 with the phenolic antioxidants are widely applied in polymeric materials including PE, PP, PS, polyamide, polycarbonate and ABS, etc.

Storage: Poor hydrolysis resistance. Avoid moisture and heat
