A low energy fuse is extruded as a single ply primary tube 1 from a plastic resin blend with particulate energetic material 2 being internally distributed in a manner known per se, said resin blend comprising a major amount of an orientable polymer, for example, linear low density polyethylene to provide structural integrity and a minor amount of a modifier to impart enhanced particle retentive properties to the tube and preferably also containing a polymer or copolymer to impart melt strength and aid in tube extrusion.

Low energy fuse and method of manufacture

Low energy fuse and method and manufacture

A non-electric low energy fuse comprises plastics tubing within which there is provided a core loading of mixed particles which are reactive or detonable to provide signal transmission means wherein the plastics tubing is an extruded tubing and has an outer skin of a hydrophilic polymer to enhance the oil resistance of the fuse.
