Detacord®(3.8g/m) detonating cord is commonly used for surface, quarrying, construction or underground blasting applications. Detacord® can also be used as surface trunklines or lead-in-lines when used in conjunction with shock tube Primadet® accessories.Detacord® detonating cord will detonate through standard knots and will initiate other detonating cords. Most cap sensitive explosives, detonating relays and cast boosters are insufficiently sensitive to be initiated by Detacord®. Confirmation of compatibility should be obtained from the manufacturer. Detacord® detonating cord is flexible, easy to handle, readily ties and holds knots. Primacord® detonating cord is simple in design and use. The high explosive core is encased in various protective coverings developed to withstand the many conditions encountered in the fi eld. The difference between the standard types of Primacord® detonating cord is essentially the core load coupled with a difference in the degree of protection afforded by the encasements. Various combinations of materials such as textiles and plastics cover the raw PETN (Pentaerythritol Tetranitrate) core. The textiles used provide tensile strength and fl exibility, as well as resistance to abrasion and cutting, extremes of heat and cold or water and oil penetration.
