The present invention relates in general to binders for melt castable plastic bonded explosives, and more particularly, to a binder system which desensitizes the explosive fill and which can be used in filling ordnance without the need for a baking step at elevated temperatures. In conventional melt castable explosives, a mixture containing an explosive such as trinitrotoluene TNT, a fuel filler of aluminum powder, and optionally cyclotrimethylene trinitromine RDX is poured into the casing of the ordnance such as a bomb casing. This explosive charge solidifies and becomes very hard. This type of explosive fill is relatively sensitive to shock and does not pass insensitive munitions requirements such as resistance to thermal cook-off and sympathetic detonation.
