Nonel is a shock tube detonator designed to initiate explosions, generally for the purpose of demolition of buildings and for use in the blasting of rock in mines and quarries. Nonel is a contraction of "non electric". [1] Instead of electric wires, a hollow plastic tube delivers the firing impulse to the detonator, making it immune to most of the hazards associated with stray electric current.
It consists of a small diameter, three-layer plastic tube coated on the innermost wall with a reactive explosive compound, which, when ignited, propagates a low energy signal, similar to a dust explosion. The reaction travels at approximately 2,000 m/s (6,500 ft/s) along the length of the tubing with minimal disturbance outside of the tube. The design of nonel detonators incorporates patented technology, including the Cushion Disk (CD)[ buzzword] and Delay Ignition Buffer (DIB)[ buzzword] to provide reliability and accuracy in all blasting applications.[ citation needed]
Nonel was invented by the Swedish company Nitro Nobel in the 1960s and 1970s, [2] under the leadership of Per-Anders Persson, [3] and launched to the demolitions market in 1973. [4] (Nitro Nobel became a part of Dyno Nobel after being sold to Norwegian Dyno Industrier AS in 1986.)
