Compounding Elastomers for Use in Armament Applications

Abstract

A commercial masterbatch of a phosphonitrilic polymer proved to be much easier to mill-mix than the gum elastomer itself. Vanfre AP-2 processing aid improved the mold flow of a nitrile-based compound developed for use in the fabrication of oil seals. Antox N was found to be a suitable antioxidant to replace Neozone D that has been removed from the market. The shape factor of 175mm neoprene rubber obturator pads was reduced by the placement of blind holes in one pad surface, hence the low-temperature compressibility was improved. Satisfactory compounds, based on polymer blends, were developed for potential use in the fabrication of obturator pads, barrier bags for the 152mm combustible-cased round, and seals for use in flame-resistant hydraulic fluid.
