High-performance propulsions systems for civilian and defence applications
Rheinmetall is an innovative partner of leading ammunition producers both at home and abroad, participating in major defence technology developments and serial production programmes.
In addition to artillery and mortar charge systems, the unit manufactures artillery charges and propellants for large-, medium- and small-calibre applications, as well as combustible cast parts such as cartridge cases.
These include the MTLS modular propelling charge system, 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, its 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 turn to the Nitrochemie Group for products used in seat belt tighteners.
Nitrochemie has been a reliable partner to companies in the chemical and pharmaceutical industries for over forty years. The company’s experience in nitration using mineral acids led to the development of processes for manufacturing chemical intermediates during the 1960s. Ever since, the production of chemical intermediates has been an essential ingredient in Nitrochemie’s success.
Along with well-established products in the field of chemical and pharmaceutical intermediates, Nitrochemie’s core competencies include silanes and silicones, acid chlorides and oxidation products, custom manufacturing and process development.
