Applications: 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.
Package: cardboard boxes with plastic liners, net weight: 20Kg / box.
Storage: Because of the low performance on hydrolyzing resistance, protection from moisture and heat is needed.
