For decades Nitrochemie is specialized in high-performance propellants for the military and civilian market as well as in the development and manufacture of chemical intermediates. Another field of expertise is the preservation of paper.

Thanks to forward-looking investment in state-of-the-art production facilities and advanced technologies, Nitrochemie has emerged today as an international leader in its field.

Reliable partner to the chemical and defence industries

In addition to artillery and mortar charge systems, charges for artillery and propellant powders for the large, medium and small calibre range, Nitrochemie does produce combustible cartridge cases. These include the MTLS modular propelling charge system (MTLS), developed for long-range self-propelled howitzers and field howitzers with high rates of fire, high-performance components for ammunition systems and the unique El propellant which was developed specifically for use in modern mortar charge systems.Furthermore, our range of products encompasses every variety of single- and multi-based propellants, with and without surface treatment and for all types of ammunition, including propellants for small-calibre hunting and sport rifles. The portfolio is rounded off by nitrocellulose and NG-paste, both important precursors in the defence technology industry.


Nitrochemie applies its defence technology expertise to special purposes in the automotive and aviation industries as well, and in medical and fastening applications. Major automotive component makers for instance turn to the Nitrochemie Group for products used in seat belt tighteners.

In the segment of chemical intermediates for civilian applications and the pharmaceutical industry, the most notable product group is silane, which is added to silicone-based sealants that are used, for example, in windows, doors and bathrooms.


Another field of expertise in the nonmilitary sector is the preservation of paper, for which the world's most advanced and largest deacidification plant is available. Using a special process of mass deacidification, it is possible to deacidify books of varying condition, newspapers and other publications.
