Detonating card consists of a core of high explosive contained in polythene and wrapped in various layers of cotton/jute yarn. The detonating cord is then coated with PVC, giving it a high tensile strength and making it water proof. The structure of detonating cord assures its efficient field performance as it is unaffected by both heat and cold within a wide range from - 60oC to 30oC. It falls under Class 6, Division 2 of Pakistan Explosive Rules.
Velocity of Detonation
6000 - 7000 m/s
In carton boxes 1000m = 4 reels X 250 m
Water Resistance can withstand pressure of 25meter-water load for 48 hours
