D2-m-Carborane-Siloxanes. VI. Oxidative Stabilization of Vulcanizates with Ferric Oxide.
Abstract
Ferric oxide produced from iron pentacarbonyl was evaluated as an oxidative stabilizer in D2-m-carborane-siloxane and polydimethylsiloxane vulcanizates. The results indicate a significant improvement in efficiency compared to powdered ferric oxide. Thus a carborane-siloxane vulcanizate retained elastomeric properties after 1000 hours in air at 315 C. The practical upper use temperature for carborane-siloxane vulcanizates was evaluated by heat aging samples at 340 and 370 C. (Author)
