ANTIOXIDANT HONOX-626 is a highly effective phosphite antioxidant which is superior to the other phosphite antioxidants in the protection of polymer’s color. It provides excellent color stabilization during compounding, fabrication and end use. It is an excellent stabilizer for reducing polymer degradation during processing. 


It is often blended with phenolic primary antioxidants such as 1010 and 1076 to prepare composite antioxidant which improves the thermo-stability of polymer processing. It is widely used in PE, PP, PS, PA, PC, ABS, PVC and many other polymer materials.   info at hhochem com
