Exel™ MS detonators are a series of full strength nonelectric detonators with millisecond (MS) delay intervals between successive firing times. Exel™ MS detonator assemblies consist of a non-electric detonator and a length of Exel™ signal tube. The detonator incorporates delay elements and >EU#3 strength base charge inside an aluminum shell. The Exel™ signal tube is a high strength, high abrasion resistant tubing which transmits the initiation signal to the detonator. One end of the signal tube is crimped into the detonator shell, and the other end is closed off by a waterproof seal.
Exel™ MS detonators provide a series of delay times suitable for surface mining, quarrying and underground operations.
Exel™ MS detonators will directly initiate cap sensitive boosters and packaged explosives. Refer to the relevant Technical Data Sheets for details.
