JOHNEX INSTANTANEOUS ELECTRIC DETONATORS contain a priming composition of RDX base charge inside a cylindrical aluminium alloy shell, with red and grey lead wires and have been designed for use in the mining industry.
JOHNEX MIGHTY ATOM is a high density 75g supersonic velocity primer consisting of pentolite which provides the ultimate in primer performance. The JOHNEX MIGHTY ATOM provides directional firing with 4 times the detonation pressure of cartridged emulsion.
INTERDET® (inter-hole/inter-row) detonators consist of a single low strength, aluminium delay detonator, attached to a length of hollow plastic shock tube. The
detonator is housed within a colour coded plastic connector block.
JOHNEX MIGHTYPRIME® is a high density supersonic velocity primer consisting of pentolite which provides the ultimate in primer performance. JOHNEX MIGHTYPRIME® provides directional firing with four times the detonating pressure of cartridged emulsion.
