Det Cord

Our detonating cords with PETN are robust and reliable

Dyno Nobel manufactures the world's most well known brands of detonating cord (det cord), available in a wide variety of coreloads (from 7.5 to 400 gr/ft) and either a textile jacket (Primacord®) or a plastic jacket (Primaline®), for a wide variety of mining explosive needs.

Primacord® Detonating CordDyno Nobel Det Cord

PRIMACORD det cords are flexible linear explosives with a core of PETN explosive encased in a textile outer jacket.  PRIMACORD detonating cords are designed for use as trunklines and/or downlines in various mining, quarrying and construction applications.

Primaline® Detonating Cord

PRIMALINE det cords are flexible linear explosives with a core of PETN explosive encased in a plastic outer jacket. PRIMALINE detonating cords are designed for use as trunklines and/or downlines in abrasive mining, quarrying and construction applications.

Primashear™ Linear Explosive

PRIMASHEAR is a low velocity, linear explosive designed for downhole use in dimension stone splitting and shearing applications.  The lower detonation pressure and velocity of PRIMASHEAR allow the user to reduce crack generation between closely spaced holes, resulting in reduced radial cracking as well as improved rock displacement.

Additional specialty cords are available.  Contact a Dyno Nobel team member for more information (800) 473-2675.
