An analysis has been performed on the impact sensitivity of paste explosive materials (PEM) with continuous physical structure containing air cavities of various sizes. It is shown that the sensitivities of PEMs based on ammonium perchlorate are strongly influenced by the extent of oxidizer decomposition during the low‐temperature stages of thermal decomposition. Mechanically non‐uniform PEMs are well sensitized by air bubbles of an optimum size.
