Besides the features of Permissible Instantaneous Electric Detonator, the Permissible MS Delay Electric Detonator has the function of time delaying. It can meet the requirements of delay time at the range of 0-100ms is accurate for delaying action. The product is suitable for use in blasting operations site where explosion hazard of marsh-gas, coal-dust or other inflammable mine dust exists and can also be applied to blasting operations of general mining, tunneling, road-building, bridge-construction and building water conservancy projects. The performance of safe application in marsh-gas can meet the requirements of national standard. The product has good safety and strong resistance to stray current and moisture and can be used to achieve the effect of large-area millisecond blasting. The blasting cord with different lengths and materials can be determined as required by customer.
