Detailed product description

WATER-RESISTANCE DETONATING CORDS

Water-Resistance Detonating Cords can be initiated by a #6 or #8 plain detonator, electric or nonelectric detonator attached to the side of the cord. Cordtex detonating cord with PETN core loads of 10 g/m and 12 g/m are most frequently used as downlines in blastholes either for directly initiating AD-1 explosives, emulsions or ANFO by means of boosters. Low energy detonating cord is used for reasons of economy. Low energy detonating cord of 5.0 gm/m PETN coreload is recommended for use in conjunction with Millisecond Delay Non-Electric Detonators.
