Heavy EM-EX LC is a booster sensitive explosive which belongs to the new generation of emulsion explosives. It is based on an ammonium nitrate solution, densely dispersed in a continuous oil phase, emulsifier and other ingredients. Because none of the ingredients is an explosive itself, Heavy EM-EX LC is very safe from the handling point of view compared to other explosives. Its water resistance is excellent and the products of detonation are free of toxic substances.
