Abstract：
Diphenylamine antioxidant AO 45, 4, 4'-Bis (alpha, alpha-dimethylbenzyl) diphenylamine (CAS No. 10081-67-1), is a highly effective non-discoloring aromatic amine type antioxidant finding utility as a thermal stabilizer in a wide variety of applications, including polyolefins, styrenics, polyols, hot melt adhesives, lubricants and polyamides. Excellent performance at processing temperatures, and strong synergy with other types of antioxidants such as phenolics and phosphites, makes AO 45 an excellent choice as a component of your thermal stabilizer package.
Applications and Performance：
Diphenylamine antioxidant AO 45, 4, 4'-Bis (alpha, alpha-dimethylbenzyl) diphenylamine (CAS No. 10081-67-1), is especially effective in polyisoprene, Neoprene, nitrile, EPDM, HNBR and acrylic rubbers. The combination of high amine antioxidant activity, good color and low volatility makes it an ideal antioxidant and heat stabilizer for rubber and plastics.
Another advantage of AO 45 is very slightly staining and discoloring in sunlight with its relatively non-discoloring during heat aging.
