Points:

1. The new phosphorous antioxidant has high effective phosphorus content, strong ability to decompose hydrogen peroxide, and better initial coloring, transparency and high temperature resistance than ordinary phosphorous antioxidant;

2. The transparency of products is good, non-toxic, tasteless and pollution-free. It can be used as food packaging material to replace antioxidant TNPP, TPP, etc.

3. Excellent thermal stability and color stability. It is a chelating agent and stabilizer in the processing of products, which can effectively inhibit the aging in the processing of products and maintain the transparency of products.

4. No phenol or phenol functional group pollution, good hydrolysis stability;

5. Good synergistic effect can be produced when used together with blocked phenolic antioxidants and ultraviolet absorbers;

6. Usage: this product can be widely used in PVC, PE, PP, PS, polyamide, polycarbonate, ABS and other high molecular materials after mixed with hindered phenolic antioxidant.

7. Storage and transportation package: the product is poor in hydrolysis resistance, and should be moisture-proof and heat-proof. Packed in iron drum, net weight 180KG/ drum.

8. Reference dosage: general dosage is 0.1-0.5%.

9. Validity: 12 months.
