Desensitisation of energetic materials

Abstract

An energetic material comprises an energetic crystalline material substantially coated in an energetic plasticiser material. Advantageously the energetic material comprises from 90 to 99% by weight of an energetic crystalline material and from 1 to 10% by weight of an energetic plasticiser material comprising a plasticiser selected from the group comprising Butane Triol trinitrate (BTTN), Trimethylanol ethane trinitrate (TMETN), Diazidonitrazapentane (DANPE), Glycidyl Azide Polymer (Azide Derivative) (GAP Azide), Bis(2,2-dinitropropyl)acetal/bis(2,2-dinitropropyl)formal (BDNPA/F) or mixtures of two or more of these plasticisers. The inventors have found that the combination of just a small quantity of energetic plasticiser material to the energetic crystalline material prior to incorporation into the bulk plasticiser, binder and filler mixture of an explosive or propellant composition has unexpected and advantageous effects.
