Product Name: ANTIOXIDANT 626
Chemical Name: Bis(2.4-di-t-butylphenyl) Pentaerythritol Diphosphite
Formula: C33H50O6P2
CAS No.: 38613-77-3
Structural formula:
Application:
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 AT-10) to prepare composite antioxidant which improves the thermo-stability of polymer processing, thus making it widely applied in PE, PP, PS, PA, PC, ABS and many other polymer materials.
