Irgafos 168, by BASF, is a Tris-(di-tertiary butyl phenyl) phosphite. It is a hydrolytically stable organo-phosphite processing stabilizer. As a secondary antioxidant, it reacts during processing with hydroperoxides formed by auto-oxidation of polymers preventing process induced degradation and extending the performance of primary antioxidants.
The application range of Irgafos 168 – synergistically combined with other BASF antioxidants – comprises polyolefins and olefin co-polymers such as polyethylene (e.g. HDPE, LLDPE), polypropylene, polybutene and ethylene vinyl acetate co-polymers as well as polycarbonates and polyamides.
