Fields of activity

Limestone fillers have a wide range of uses. The quality of the deposits in our partner’s quarry meets all the physical and chemical criteria and standards required by the industrial, construction and public works sectors.

Agri-industry, animal feed, chemicals, construction and public works : our micronized limestones are much in demand

Micronized limestone has to meet specific criteria, which differ from one sector to another. Our laboratory analyzes it to make sure that the intrinsic properties of the raw material in question is in line with the standards required by the relevant sector.

Consistency and uniformity, particle size, whiteness, calcium content, flowability, Methylene Blue Value, oil absorption value - our fillers are selected for their ability to perform all functions required of them in a range of industrial applications.

Our limestone fillers can be used for a variety of applications :

filler moquette latex

Carpet backing, rubber and compounds

Our products increase viscosity when mixed with rubber and other compounds or plastic composites.

We sell top-quality limestone fillers extracted from the Carrières de la Vallée Heureuse quarry in France’s Pas-de-Calais area. The intrinsic physical and chemical propertiesof our limestone and our micronization techniques are of major benefit to many industries. We shift our focus and adapt our products to keep pace with ongoing technological progress thanks to our partner CVH’s laboratory.

Our products

Our limestone has a content of over 96% CaCO3. This extremely high level allows us to meet the specifications of the industrial and agricultural sectors. The particle size of our fillers meets all relevant product requirements and complies with all standards and regulations currently in force.
