Who we are

Target shooters or hunters who demand absolute precision depend on ammunition they load themselves. The right propellant plays a key role among reloading components. Uniform quality and burn performance enable precise, highly repeatable hits – under the most varied weather conditions.

Reload Swiss RS®, the new brand from Nitrochemie, offers the perfect powder for perfect hits - thanks to pure Swiss-made precision!

The development and production of Reload Swiss RS® propellant powders are based on almost 100 years of experience of internationally renowned Nitrochemie Wimmis AG with high-performance powders.

Constant quality assurance from production to packaging ensures uniform fabrication quality for the most demanding shooters.

A high-performance distribution network throughout Europe provides for reliable availability.

Nitrochemie and its distribution partners are always at our customers’ service when it comes to sharing load data, tips and experience, so as to continually expand and spread the knowledge base of Reload Swiss RS® products.

Reload Swiss RS® products have already earned the confidence of some of the world’s top competitive shooters.

The Nitrochemie-Group

The Nitrochemie Group is a leading manufacturer for propellant charges whose core competence lies in the development and manufacture of propellant charges for military and civilian use.

The offerings of this business line also include all types of single- and multiple-base propellant powders with and without surface treatment for the entire ammunition spectrum, including propellant powder for hunting and sport applications in small calibres. Nitrocellulose and propellant pastes are additionally manufactured and sold as intermediate products for military use.


The knowhow acquired in the military segment is also used for special applications in the automotive and aeronautics industries as well as for medical and fastening applications. We supply major automotive suppliers with products for seatbelt tensioners and for airbag safety components.

In the area of chemical intermediate products for the civil and pharmaceutical industries, silanes (silicone hardeners) make up the largest product group; these are used as additives in silicone-based sealants for example for windows, doors or in sanitary facilities.

Paper preservation is a further competence sector. For this purpose, we maintain the world’s largest and most modern deacidification system of its type. Using a special mass deacidification process, this system is able to deacidify books of different types, newspapers and other written matter.

With pioneering investments in modern production equipment and future-oriented technologies, Nitrochemie is already one of the global leaders in its product areas. Intensive cooperation with customers, market-oriented research and short paths between sales, development and production make Nitrochemie a competent partner for development projects anywhere in the world.
