Floor Plan

The spherical powder is a nitro-cellulose smokeless powder manufactured according to an original process developed in the years 30s, by the “Olin Mathieson Chemical Corporation” -USA.

The wet process technique is used for the manufacture of this powder, which is in fact its most essential and typical feature. The process combines increased safety with high flexibility and adaptation to numerous applications.

The spherical powder is generally a double base smokeless powder, coated with a burning modifier that ensures a progressive combustion and consequently optimal ballistic properties. The grains are graphited and may have their surface covered by a flash-less agent and, in some cases, a copper less-agent. The bulk density can range between 500 and 1050g/l.

The spherical powder is perfectly suitable for the loading of all types of military ammunitions (including blank) for calibre up to 40 mm, as well as for mortar bombs. It satisfies the most severe specifications. It meets the NATO requirements, as well as the national ones (Europeans, Russians, ...).

Spherical powder is also perfectly suitable for the loading of civilian ammunitions for rifle or handgun satisfying the CIP and
/or SAAMI requirements.

Beside shotshells for sport or hunting, ammunitions for competition or peace keeping forces, it is also used in many other applications like: power tools, breaking charges in spatial application, ammunitions for cattle killing, cartridges for furnaces cleaning in cement industry, cartridges for gas generators in the automotive industry, ...

Spherical powders present superiority over conventional
powders:

A better physical and chemical stability
A better storage guarantee
Less barrel wear due to a lower flame temperature
Reduced hygroscopicity
Higher bulk density
Improved loading density in connection also with the excellent free flowing characteristics
Ballistic uniformity at extreme utilisation temperatures

Created in January 2004 to bring together the French, Belgian and Swedish Explosives & Propellants activities, EURENCO inherited its prestigious predecessors’ (SNPE and Bofors) centuries of in-depth knowledge of energetic materials.

In December 2013, Groupe SNPE (owner of EURENCO) was acquired by GIAT Industries (parent company of the NEXTER Group).

Ranges of EURENCO products are marketed through specific brands:

Bofors Powders: propellants for hunting, sporting and law enforcement
MANUCO: energetic nitrocellulose for propellants and propelling charges
PB Clermont: spherical powders for small and medium caliber ammunition
VeryOne: 2-EHN cetane improver for diesel fuels

From its headquarters based South of Paris (Massy •), EURENCO operates 4 modern production plants in France (Bergerac •, Sorgues •), Belgium (Clermont •) and Sweden (Karlskoga •).

EURENCO is also present in the United States, through a commercial office in Washington DC • (for explosives, propellants and combustible items) and a distribution company in Houston • (for fuel additives).

In order to meet the strong market demand, EURENCO also runs a number of storage facilities worldwide, among which one of the largest storage parks for pyrotechnics in continental Europe.

PB Clermont, standing for “Poudrerie Belge de Clermont”, was founded in 1850 and is one of the world’s most experienced propellant manufacturers.

PB Clermont produces exclusively spherical propellants, a nitrocellulose smokeless powder suitable for:

small and medium caliber (up to 25 mm) ammunition
civil applications (power tools)
mortar rounds secondary charges Spherical powders provide an improved loading of cartridges due to an excellent flowability, excellent physical and chemical stability, as well as lower barrel erosion.

Faced with an extensive and highly diversified worldwide market, PB Clermont has made a point of listening carefully to customer requirement and trends, in order to constantly enhance, optimize or innovate.
