ANTIOXIDANT HONOX-626 is a highly effective ste antioxidant which is superior to the other ste antioxidants in the protection of polymer's color. It provides exnt color stabilization during compounding, fabrication and end use. It is an exnt stabilizer for reducing polymer degradation during processing.
It is often blended with nolic 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
