초록

The invention relates to Insensitive Munition (IM) energetic materials particularly IM propellant compositions, and yet further to nitrocellulose-free IM propellants. An energetic composition suitable for use as a propellant comprises the following components in the following relative proportions: component A; from 5% to 25% by weight of an IM energetic filler; component B: from 50% to 80% by weight of a highly energetic filler comprising at least one nitramine compound; component C of from 5% to 20% by weight of a binder; and component D of from 3% to 1...
