Compared with common phosphite antioxidants, this product has higher phosphorus content (antioxidant functional group) and higher antioxidant activity. It is a high-performance phosphite antioxidant. The addition of SONOX 626 allows the polymer to be effectively protected under high temperature processing conditions and allows the polymer to achieve excellent multiple processing stability.
Packed in a carton lined with plastic bags, 20KG/carton; not suitable for exposure, heat and moisture during storage and transportation. Store in a cool, dry and ventilated place, and store and transport according to the general chemical products.
This product is a high-performance antioxidant. The antioxidant activity of this product is better than other phosphites. It can make the polymer better processed under the condition of adding half of the common phosphite antioxidant. stability.
This product is generally not used alone, and is often used in combination with a phenolic primary antioxidant such as antioxidant 1010. This product is widely used in PP, PE, PS, PA, PC, ABS and other polymer materials after compounding with phenolic antioxidants. The general dosage is from 0.1% to 0.3%.
