Plasticized Ethylene - Vinyl Acetate Binders for Insensitive Booster Compositions

摘要

Plasticizers have been incorporated into RDX ethylene-vinyl acetate (EVA)compositions prepared by the solvent slurry coating technique. The effect of plasticizers on impact sensitiveness, shock sensitivity, cookoff behavior and integrity of pressed pellets has been examined for compositions with EVA binders of varying vinyl acetate content. A compatible EVA plasticizer combination gave an appreciable reduction in cookoff response and impact sensitiveness. Plasticizer migration is likely to affect the long-term stability of these compositions.
