Abstract: A priming explosive is produced by mixing an aqueous solution of a finely divided explosive substance such as in colloidal form with a plastic polymeric carrier and a plasticizer whereby the explosive substance is rendered mechanically workable and has little sensitivity to mechanical shock and electrical impulses. The resulting plastic product is then molded by conventional molding techniques into sheets or films and used as a primer, optionally, by itself without any metal parts. The molded product may be applied to a main explosive mass as a coating or as a strip or it can be formed as a condensor of alternating conductive and insulative layers which is detonated by electrical impulse.
