摘要： A low energy fuse, comprising a plastic tube with a channel, the channel containing a reactive material able upon ignition to sustain a shock wave within the channel, the tube comprising at least two layers of plastic materials, a first plastic layer closer to the channel and a second plastic layer outside the first layer, at least the second layer containing a major amount of draw orientable polymer resin. The polymer in the second layer is axially oriented to an orientation degree (as defined) of more than 25 % and less than 90 % and that the polymer of the first layer has an axial orientation degree not exceeding 10 % orientation degree units more than that of the second layer. The tube can be manufactured by a) forming, by extrusion of the first layer plastic, the first layer in the form of a tube, b) introducing the reactive material in the tube channel, c) limiting stretching of the first layer to give a low degree of orientation, not exceeding 10 % (as defined), d) forming, by extrusion of the second layer plastic, the second layer around the first tube, while the first layer have said low degree of orientation, and e) cold-stretching the first and second layers together.
