SB Cord™ (8g/m) detonating cord is used for secondary blasting. SB Cord™ detonating cord does not exhibit the tensile and abrasive resistant properties of the other Primacord® detonating cords due to the exclusion of the outer layers of protective yarns and wax, however is compatible with all cap sensitive products and can be used with detonating relays.SB Cord™ detonating cord will detonate through standard knots and will initiate other detonating cords. B Cord™ detonating cord is not recommended for underground use or applications. 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.
