High performance pressable explosive compositions

Abstract

High solids pressable explosive compositions containing a liquid energetic polymer and a high performance explosive oxidizer are disclosed. The pressable explosive compositions contain a solids content between 91 and 99 weight percent, with an energetic polymer content less than 9 weight percent. The energetic polymer has a weight average molecular weight greater than 10,000, determined using a polystyrene standard, sufficient to use the polymer precipitation technique in preparing the pressable explosive compositions. Chain-extended PGN (polyglycidyl nitrate) is a preferred energetic polymer. The pressable explosives disclosed herein produce extremely high detonation pressure, high detonation velocity, and excellent metal accelerating capability.
