Sibirit-P™ is a substance intended to be applied in cartridges as a booster at initiating detonation in borehole charges for the blastholes with any degree of water presence and as charges for secondary crushing of oversize rock, with the following parameters:
- cartridge diameter - 50 mm, charge weight - 800+50g;
- cartridge diameter - 50 mm, charge weight - 300+50g;
- wrapping - polyethylene film or other polymeric material.
The product will perform in temperatures ( free-air temperature) from +40oC to -35oC.
Main physical-chemical and explosive properties of Sibirit-P™ are given in the Table below.
