PRODUCT FEATURES AND APPLICATIONS
 AN 168 is secondary antioxidant with excellent resistance to extraction by water, low volatility and high heat stability. It reacts during processing with hydroperoxides formed by autoxidation of polymers preventing process induced degradation and extending the performance of primary antioxidants
 AN 168 has better synergist effort with Primary Antioxidant  AN 1010.
 AN 168 is of good compatibility with most Polyolefin like ABS,PC,PVC,PU, Polyester, PP,PS PBT,PET,PMMA,TPE and etc
