Detonation cord
Detonation cord has a laminated cotton-fiber sheath, the outermost is a PVC sheath, with good water resistance
- Introduction
The detonation cord has a multi-layer cotton fiber sheath, the outermost is a PVC sheath, has good water resistance. The low energy explosive wire type 5 g/m is mainly used as inner blasting band open mines or explosion network connection in the blasting of underground structures, it transmits the detonation through the joints and detonates the non-electric detonator very well. The 10 g/m and 12 g/m detonation cords are used to detonate multiple mines when connected together. - Specifications

Detonation cord is rolled into rolls of 50m, 200m or 250m (depending on each type), stored in a sealed PE bag, then stored in a paper box or wooden box. When the product is used, open the box to get enough materials that are needed only, the left-over must be stored in PE bags and in a paper box or wooden box. Detonation cord is an explosive material with high explosion rate, it must be stored in dry, cool, termite-free, rat-free, leak-proof warehouses with guaranteed lightning protection system.
