2.0 x more powerful than the next best packaged explosive at 5,121 j/g energy capacity

Speed of deflagration
340 m/s – Ensuring minimal vibration impact to surrounding environment

Pressure
500 MPa – With reaction runaway, AutoStem Cartridges reach maximum pressure within milliseconds sufficient to break out the hardest rock

Density
1.1 g/cm3 – Highest packing and mix density makes Gen III Cartridges the most powerful blasting cartridge available worldwide

Vibration
PPV reduction relative to conventional explosives by up to 90% (depending on cartridge size, rock competency and application type)
