Mineralia®, Supplier introduction.

August 3, 2020 11:40 am Published by

Mineralia® is dedicated to the extraction and micronization of minerals.

In the next of our supplier introductions, we are pleased to introduce Mineralia® who offer micronization of natural minerals for industrial applications: Barite, Talc, Dolomite, Quartz, Kaolin, Mica and Slate.

Since its inception in 1978, Mineralia® has remained faithful to the original aim of providing a wide range of products in order to fulfil market needs.

In a constantly changing world, mineralia® is always attentive to new developments in the world of micronization of minerals and they continue to develop and improve their technology in order to offer the widest possible range of micronized barite, talc, mica, dolomite, kaolin, quartz and slate to suit all industrial sectors.

This continuous innovation and improvement have made Mineralia® one of the main European producers of micronized natural barium sulphate and talc. MegaChem have great pleasure in offering their range of products to the UK market.

Main focus.


Offering a wide range of micronized barite products for the manufacture all kinds of industrial paints whether in liquid or powder form. Among the most prominent applications are paints: automotive, anti-corrosion, marine, road, pavement, etc. The use of talc, mica or quartz is also common in this sector.

Their products improve both dispersion of solids and chemical inertness. their Blanc Roc® range can replace precipitated barites and extend TiO2, whilst working with greener products. They also provide chemical stability, protection against corrosion, and a good index of refraction among other qualities.

They also have different ranges of silicates in the form of talc, mica or kaolin, which, due to their lamellarity, offer a barrier effect against moisture while also providing very good resistance to burnishing, good brightness, thermal and acoustic insulation, and assisting film levelling.


A large variety of coatings are available for all types of surfaces in the field of interior and exterior decoration: concrete, plaster, wood, metal, concrete, plastic, etc.: all of which can be optimized with the use of suitable mineral fillers.

Their Dolkron® range of natural dolomites provides opacity and chemical resistance to white paints for outdoor use.

The Talkron® talcs and KaoFlor® kaolins provide softness to the touch to water-based interior paints, and the ability to repel moisture to exterior paints. Thanks to their excellent laminarity, they also provide optimal satin finishes in wood paints and primers.

BariStar® natural barites not only provide whiteness and reduce oil absorption: they also help improve the strength and durability of exterior paints exposed to all kinds of weather.


In the complex plastics industry, the use of mineral fillers in extrusion and/or direct injection processes is now widespread.

In Masterbatch production, Talkron® talcs improve mechanical strength, flexibility and dimensional stability, while density and chemical resistance are achieved with the use of BariStar® and BariFlor® barites.

In the world of drainage pipes, the use of their products adds soundproofing and density to the final product. With proper distribution of particles, we help their customers meet the highest quality standards.

As well as our standard products, their technology allows them to adapt to the individual requirements of each manufacturer. In addition, the Blanc Roc ® family helps optimize the use of pigment due to its high level of whiteness.

All their products comply with the main European food contact standards (for packaging) and with EN-71 Part 3 (toy safety).


Due to the characteristics inherent to barite ore and to correct particle size, BariFlor®, BariNit® and BariStone® products manage to create a barrier that prevents the propagation of sound, heat and X-rays in different types of panels and coatings.

It is used within the automotive industry in floor mats and hood coatings, in order to insulate the vehicle’s interior from engine noise.

The MicaFlor® range of micas also provides electrical and thermal insulation.


The main reasons for incorporating natural barites like our Blanc Roc®, BariStar® or BariFlor® ranges to mortar, putties and adhesive formulations are improved mechanical and chemical resistance, as well as their high specific gravity and low oil absorption. All these features allow the manufacture of products with a high concentration of solids while saving resin and thereby reducing costs.

As in the case of insulators, silicones benefit from barite’s ability to reduce noise when used within the automotive and construction fields in metal frameworks and glass assembly.


In the context of growing demand for high-density concrete for large public projects like piers, bridges or hospital X-ray rooms, Mineralia® has developed the BariStone® product range. Due to their high density, these raw materials also have the ability to block UV, Gamma and X-rays.

They offer barite concentrate aggregates in different particle size distributions that meet the requirements of the sector and help improve the efficiency of the concrete manufacturing process.

We have a range of products from Mineralia® products available from our UK warehouse. Grades not stocked are available on an Extended lead-time. Should you have a specific need or requirement for the products from Mineralia®, please do not hesitate the team here at MegaChem.

Please stay tuned for our next supplier focus later this month.
