Title: Flexible, self supporting, plastic bonded high explosive compositions
Inventor: BULLOCK ALAN RICHARD HOWARD
IPC: C06B21/00
Filed: 1984-09-27
Abstract: A plastic bonded high explosive which is flexible, self supporting and water resistant. This comprises an intimate and uniform mixture of between 60-92% by weight of a particulate high explosive and 8-40% by weight of a thermo-elastomeric binder system. The elastomer referred to in this system is a block copolymer of polyether and polyamide. This may be used alone or in conjunction with polyisobutylene to act as an extender/tackifier and may be up to 50% by weight of the binder system. If desired further plastisizers may be employed. Amongst the explosives that may be used in this invention are PETN, RDX and HMX. The explosive formulations may be made by dissolving the binder in a suitable solvent and then adding the explosive followed by a drying step. Alternatively the formulation may be made "dry" in a suitably heated vessel.
