NURCHEM AO-626 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 antioxidant (such as AO-1010) to prepare composite antioxidant which improves the thermo-stability of polymer processing.

It is widely applied in PE, PP, PS, PA, PC, ABS and many other polymer materials.
