Characteristics and Uses: 
Antioxidant 626 is a high-effective solid phosphite ester antioxidant, which is superior to other phosphite ester in the effective protection of polymers' color. It can be dissolved in toluene and dichloromethane. It is often blended with phenolic principal antioxidant (such as AT-10) 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.
 

Storing and Packing: 
Because of the low performance on hydrolyzing resistance, protection from moisture and heat is needed. The package should be cardboard boxes with plastic liners, net weight: 25Kg / box or base on customer's demand.
