EM-EX Contour

EM-EX Contour is a cap sensitive emulsion explosive. It is specially developed for smooth blasting in surface excavations, in tunnels during contour construction, in presplitting as well as in cautious blasting where there are problems with vibrations. The small cartridge diameter gives a Low Loading density, resulting in a mild blasting effect. Rock over-break is minimized. The length of 510 mm makes charging fast and easy. As an emulsion explosive, EM-EX Contour has excellent water resistance, and the products of detonation do not contain toxic substances.
