Definitions

  • ABSTRACT OF THE DISCLOSURE Detonating fuse-cord is manufactured by feeding a special grade of free-flowing granular PETN through a die, continuously forming a sheath around the stream of PETN and subjecting the resulting fuse-cord to a pressure sufiicient to consolidate the granules into a core.
  • the special grade of granular PETN is made by treating fine crystalline particles of PETN with a binding agent and aggregating into granules.
