DADNPO is a new explosive which can tolerate temperatures about 40°C higher than HNS, with the same degree of degradation. This explosive can therefore be used in hotter holes than HNS shaped charges for oil well completion, with equal performance.

EURENCO can provide sample quantities of this compound through small-scale production.
