Multi-Applications Detonating Cord
Pyroalliance designs and manufactures a complete family of detonating cords dedicated to transmit a pyrotechnic signal, induce an ultra-short time delay or used for structure weakening / breakage.
Those can be made of different metallic materials and various explosive types depending on the application requirements. Pyroalliance has the ability to propose detonating cords with specific plastic coating and/or armoured braiding.
More generally, Pyroalliance delivers complete pyrotechnic chains adapted to its customers’ needs. They are designed and manufactured under Pyroalliance design authority.

Benefits of pyrotechnics
- Many references of detonating cords can be made available that will be selected on the basis of the targeted application and their associated environmental conditions.
- Geometrical section can vary in diameter from ~1.5mm to ~5mm for detonating cords with traditional circular section. Flat section is also possible for specific applications.
- Depending again on the considered application, detonating cords can be delivered in different conditioning sets from simple straight strands of few centimetres to ~300 meters long rolls.
- The metallic envelope can be made of lead or aluminium and the explosive core is most generally made of RDX, HMX or HNS.
- For transmission functions, detonating cords are covered by a specific plastic coating and/or armoured braiding to form a transmission line.
Defence applications
- Detonating transfer lines
- Pyrotechnic delays for military warheads
- Canopy severance
- Frangible joint assembly
- Structure weakening or breakage
