Thin composite explosive products and preparation thereof

Abstract

A composite explosive product, wherein its composition expressed as percentages by weight includes 85% to 92% of organic energetic charges; the organic energetic charges a) being selected from charges of octogen (HMX), hexogen (RDX), hexanitrohexaazaisowurtzitane (CL20), penthrite (PETN), and mixtures thereof, and b) presenting a grain size distribution with a value for D90 less than 15 μm and a value for D50 less than or equal to 5 μm; and 7% to 12% of a polymer gum selected from polyurethane-polyester gums, polyurethane-polyether gums, and mixtures thereof, of number average molecular weight greater than 20,000 g/mol and of Mooney viscosity lying in the range 20 to 70 ML (5+4) at 100° C.; and wherein the composite explosive product has a thickness lying in the range 0.4 mm to 5 mm.
