High detonation velocity ideal for initiation of ANFO columns

Senatel™ Ultrex™ is a water resistant packaged explosive designed for priming applications, and as a medium energy column explosiuve, in surface/underground mining and general blasting. The high detonation velocity and the robust nature of Senatel™ Ultrex™ allow the product to be used as a primer for the initiation ANFO columns. Cartridges can be readily split during tamping to maximise coupling and bulk strength within blast holes. Senatel™ Ultrex™ brings greater energy to perform effectively as a column charge in very hard rock or as a bottom charge in soft rock. This robust product’s high detonation velocity makes it an ideal primer for the initiation of ANFO columns.
