Quantex® 73

producto exsa

Is the explosive mixture composed of a 70% gasifiable emulsion; Slurrex Q, enhanced with 30% Quantex ammonium nitrate, which is then added a gasifying solution that provides the required sensitivity and density desired according to the blasting design.

The explosive mixture QUANTEX® 73 is specially designed for hard rocks.

The main benefits of QUANTEX® 73 are:

  • Excellent resistance to water
  • Bulk explosive easy to operate in the field (pumped or emptied).
  • It adapts to different types of terrain due to its high density range.
  • It is friendly to the environment by reducing the carbon footprint by 18%, compared to conventional explosives (SGS).
  • Optimizes the blasting which maximizes the result in the rock fragmentation.
  • Its design allows quick identification of whether gasification was optimally achieved.
  • Optimizes storage spaces, the Slurrex Q (inert) does not require safety distances according to current legislation.
