Owing to its stability at high temperature and its excellent performance, HNS has several applications in the aerospace, ammunition and oil & gas industries, where thermal and/or vacuum stability are required.
EURENCO produces HNS in all particle sizes, for different applications:
- HNS Type I for space and military pyrotechnical devices (cap relays, detonating cords, transmission cords and booster charges for I.M. applications): it brings heat resistance, low sensitivity and high performance.
- HNS Type II for shaped charges for the oil & gas industry: thanks to excellent thermal stability, it is used in perforating and cutting charges when the requirement of high temperature resistance is important.
- HNS Type III for artillery ammunition filling: it is used as anti-crack additive in TNT-based compositions.
- HNS Type IV for slapper detonators: due to high sensitivity and good reliability characteristics, it is used as an ignition explosive in slapper detonators (the surface area is above 10 m²/g). A purification process makes it significantly more thermally stable than stipulated in military specifications.
