  • Applications

    Cyclotetramethylene tetranitramine, wet with ≥10% water (CAS 2691-41-0), is a high-energy explosive used primarily in defense and security applications in its damp form. In the mining and construction industries, it serves as a high-energy explosive component for rock blasting and excavation charges. In the manufacture of plastic explosives, it is used as a main energetic ingredient or additive to boost detonation performance. It is also employed as a booster charge in detonator systems and in research and development of energetic materials. Additional applications include demolition of structures and specialized blasting projects, with compliance to safety regulations and local handling requirements.
