Initiating Products

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 MEGAPRIME is a Pentolite cast booster with a plastic protective outer shell.
MEGADET® detonators are a series of high strength non-electric detonators with millisecond delay intervals ranging from 0 ms (instantaneous) to 1000 ms.
JOHNEX EZIPRIME provides directional firing with twice the detonating pressure of cartridge emulsion.
