FIREWORK FUSES / IGNITER CORDS

Firework fuses are used in pyrotechnics to ignite pyrotechnic compositions, in rockets and firecrackers. They must not be used for blasting work. In military products they are used as ignition delays. The structure and manufacture of the firework fuse is similar to that of the typical safety fuse, from which it differs in that the raw cord (powder core with textile braiding) is coated with special glue for reinforcement and stabilization. It can also be supplied in a waterproof version. Thanks to the exact recipe variations of the fuse powder, an exact burning time as well as a strong spark output can be achieved. These sparks ensure reliable and precise ignition. The firework fuses are not supplied in rolls but in cut length that correspond to the desired burning time.

In the military field, WANO meets the high demands of the technical delivery conditions (TL) of the Technical Terms of Delivery of the Federal Office of Bundeswehr Equipment, Information, Technology and In-Service Support (BAAINBw), as well as various national and international standards. This makes WANO a reliable supplier in demand to defense industry companies worldwide.

Igniter cords consist of a special black powder core, encased in a layer of fine textile threads and a plastic film and are finally impregnated with glue. A thin metal wire in the middle accelerates heat conduction while providing the necessary strength and allowing for easy twisting. Their flexural rigidity allows them to be easily routed into almost any structure and ensures they stay in place. Foils burn with an open flame and at a much higher speed than firework and safety fuses. They are ideal ignition and flame transfer agents when burning large fireworks.
