INSENSITIVE EXPLOSIVES
NTO
AND COMPOSITIONS
Low Sensitivity High Explosive
Leading worldwide specialist in the field of high explosives, EURENCO offers its customers a complete
range of high explosives and compositions thanks to high-tech manufacturing capabilities. Always in the
forefront of innovation, the company also develops and produces NTO, a very low sensitivity molecule
for insensitive explosive compositions.
Application and user’s advantages
• Very low vulnerability, enhanced thermal stability, high performance
• Used in low sensitivity melt-cast explosive compositions
• Used in pressed and cast PBX charges for insensitive munitions.
