ANTIOXIDANT HONOX-626 is a highly effectivephosphiteantioxidant which is superior to the otherphosphiteantioxidants 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 primaryantioxidantssuch as1010and 1076to 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
