| Product name: | Antioxidant 168 | ||
| Chemical Name: | Tris-(2.4-di-t-butylphenyl) - phosphate | ||
| CAS： | 31570-04-4 | ||
| Molecular weight: | 646 | ||
| Molecular formula: | C42H63O3P | ||
| Usage: | The product is a kind of high-effective solid phosphite ester antioxidant, which is superior to other phosphite ester in the effective protection of polymers’ color. It is often blended with phenolic principal antioxidant (such as 1010) to prepare composite antioxidant which improves the thermostability of polymer processing, thus making it widely applied in PE, PP, PS, PA, PC, ABS and many other polymer materials. | ||
