Abstract:
This paper presents the results of investigation of the detonation velocity of an emulsion explosive (HE) sensitized with Expancel polymer microballoons in a wide range of initial density of 0.14–1.33 g/cm$^3$. It is shown that when the density of the emulsion explosive is less than 0.4 g/cm$^3$, detonation with an unstable front characteristic of liquid explosives is possible.
