Development of Improved Rubber Compounds for Use in Weapon Applications
Abstract
Two rubber compounds were developed for use with the new flame- resistant synthetic hydraulic fluid, MIL-H-83282. A new rubber compound was developed for use in obturator pads for bag-loaded cannons. The effects of hydrazine on the physical properties of various elastomers were determined, and several compounds were developed for potential use in this medium. Fluorosilicone rubber inserts for machine gun springs were tested and an ECO for their use was initiated. Blending of conventional silicones with fluorosilicone rubber was studied with the goal of preparing vulcanizates having good low temperature performance and elastic recovery with only a small compromise in oil resistance. In general, the poorer properties of the elastomers involved predominated, although one blend (Silastics LS63U and 651) exhibited good potential for attaining the goal. Polyphosphazene vulcanizates exhibited good low-temperature flexibility and resistance to oils, fuels, ozones, and hydrolytic stability. Also, these vulcanizates are nonflammable.
