JOHNEX EZICORD detonating cord consists of a continuous core of Pentaerythritol Tetranitrate (PETN) enclosed by tape, wrapped with natural and/or synthetic yarns and sheathed in plastic. Nominal core loads are 4, 5, 6, 10 and 11 grams per linear metre (g/m).
JOHNEX LP DETONATORS are a series of non-electric, long period delay detonators featuring 16 delays for use in the mining industry. (25 to 9000 milliseconds) JOHNEX MS DETONATORS are a series of non electric, millisecond period delay detonators featuring 19 delays for use in the mining industry (0 to 2000 milliseconds).
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 MEGAPRIME is a Pentolite cast booster with a plastic protective outer shell.
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.
