Compound parts polymer, 100 Naugard 445 (substituted diphenylamine), 2 Armeen 18D (octadecylamine), 0.5 stearic acid, 1.5 Vanfre VAM (complex organic aUsyl acid), 1.0 FEF Carbon Black (N550), 60 DIAK 1 (hexamethylene-diamine carbamate), 1.5 and DOTG, 4. 

Naugard HMll is a granular blend of hindered phenolic and diphenylamine antioxidants. This blend provides synergistic short and long term thermal protection against oxidation in polypropylene. 

Naugard 438L is a liquid nonylated diphenylamine antioxidant finding use in carbon black pigmented styrenic (ABS) and polyethylene formulations. Its liquid form allows for easy handling and incorporation into various matrices. 

The best heat resistance may be obtained with a combination of 1-2 phr zinc 2-mercapto-toluimidiazole (Vanox ZMTI) and 1-2 phr 4,4 -bis(a,-dimethylbenzyl) diphenylamine (Naugard 445) or diphenylamine-acetone reaction product (AgeRite Superflex). 

Examples of alkoxy and peroxy radical trap antioxidants are hindered amines (i.e., octylated diphenylamine, Octamine) and phenols (i.e., butylated hydroxytoluene, Naugard BHT).
