[1] Ensign-Bickford sold their registered trademark for Primacord to Dyno Nobel in 2003.
[citation needed] Primacord consists of a continuous core of PETN, RDX or other high explosive, bound by textile yarns and finished with plastic and wax as waterproofing agents.
[3] It is produced in eight strengths: Primaline is a related product differing principally in having a plastic jacket instead of textile.
Primaline is also available in higher loadings, up to 85 g/m (400 gr/ft): Primacord is initiated with a blasting cap or by a donor line of detonating cord or other high explosive.
It detonates along its entire length at a velocity of approximately 23,000 feet (7,000 meters) per second.
