EMSIT®
EMSIT® V
The EMSIT® V opencast explosive is a modern emulsion type with a high detonation velocity and outstanding resistance to water. The explosive is packaged by a modern cartridge machine into a thermally and mechanically resistant foil with a high strength weld.
It is used in large diameters as an efficient explosive during blast works, where wet or saturated blast holes occur.
Contrary to the EMSIT® M explosive, EMSIT® V has a stiffer consistency. It is necessary to use an initiating explosive charge for detonation with a velocity of detonation of at least 6,000 m/s
EMSIT® M & EMSIT® 1
Underground blasting agent EMSIT® M and EMSIT® 1 is an explosive of modern emulsion type with a high velocity of detonation and excellent resistance to water. The explosive is packaged by a modern cartridge machine into a thermally and mechanically resistant foil with a very strong weld. It is used in small and large diameters as an efficient explosive during blasting works, where wet or saturated blast holes occur. It has also found application during underground blasting works.
It is cap sensitive.
