Properties
Insensitive explosives are characterized by low porosity and high homogeneity
of the material, which leads to:
Excellent thermal and thermomechanical stability,
Very long life duration,
Low vulnerability to intentional or accidental threats,
Reliability and process reproducibility,
High performance adapted to every type of application: missile
warheads, torpedoes, underwater mines, general purpose and penetrator
bombs, shaped charges, navy shells, mortar, tank and artillery shells…

This new technology brings many useful advantages in comparison with
traditional TNT-based explosive charges. The use of cast PBX technology
allows not only the reduction of vulnerability to threats, but also the
improvement of life duration and reliability (no risk of cracks or exudation),
and facilitates logistics (storage, transportation, handling…) while
providing top level performance.
