7The invention is an insensitive energetic composition that is an explosive and the related articles and systems. The composition has HMX or RDX as an energetic filler, a nonenergetic binder and an energetic plasticizer. The plasticizer is a nitrato-nitramine or a liquid nitrate ester. This provides a matrix with a glass transition temperature below minus 45 degrees Centigrade. In another variation, the composition can also include aluminum powder. Generally, the materials have particularly strong blast effects.
An insensitive energetic composition for use as an explosive in munitions, said composition being clusters of coated powder where the powder is a crystalline heterocyclic nitramine and the coating is a combination of a normally solid cellulose acetate ester and at least one member selected from alkyl nitrato nitramine and a liquid alkyl nitrate ester, and where: (a) the crystalline heterocyclic nitramine is HMX or RDX and is the principal energetic filler in the composition and is present in about 85 to about 87% by weight, (b) the acetate ester function...
