CA 2689318

The invention relates to a method for determining the sensitive or insensitive nature of a crystallised hexogen. The method comprises the following steps: formulation of the crystallised hexogen in a matrix; and analysis of a sample of the matrix loaded with the crystallised hexogen by means of differential scanning calorimetry, said matrix essentially comprising at least one liquid polymer suitable for the formulation of binders for energetic materials loaded with nitrated organic explosives and at least one volatile organic compound adsorption agent, said agent being stable at the temperature at which the analysis is performed and having low affinity for water. The invention also relates to the hexogen crystallised in one such matrix.

La présente invention a pour objet un procédé de détermination du caractère sensible ou insensible d'un hexogènecristallisé. Ledit procédé comprend : la formulation dudit hexogènecristallisédans une matrice; l'analyse d'un échantillon de ladite matrice chargée en ledit hexogène cristallisé par calorimétrie différentielle à balayage; ladite matrice étant essentiellement constituéed'au moins un polymère liquide convenant à la formulation deliants pour matériaux énergétiques chargés en explosifs organiques nitrés; et d'au moinsun adsorbant de composés organiques volatils, stable à la température de mise en uvre de l'analyse et présentant une faible affinité pour l'eau. La présenteinvention a également pour objet l'hexogène cristallisé dans une telle matrice.
