Abstract:

Aging studies and the effectiveness of antioxidants for elastomers are discussed. Cumene oxidation indicates antimony oxide and chlorinated paraffins protect materials by altering the path of oxidation. Ethylene propylene copolymer can be protected with Hypalon 40 and antimony sulfide polyurethanes are not protected by Sb2O3 and chlorinated paraffins. Aging of protected polyethylene in a mild gamma field at 450 F in air causes severe degradation. Steam and water aging of materials containing Sb2O3 and Hypalon absorb sizeable amounts of water. Materials protected with Sb2O3 and chlorinated paraffins should not be employed in contact with Fe or Cu, unless air is precluded from the area of contact these metals reduce the level of protection.
