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. It is used to create explosive effects and to build reliable explosive charges. It is used in conjunction with other high explosive materials to form charges, including linear charges, capable of near instantaneous results.4
