Essential component in the manufacture of rubber products derived

Rubber industry makes extensive use of mineral fillers during its production process. For example, vulcanization is a chemical process that, with the addition of sulfur, changes the molecular structure of a polymer, allowing to obtain the required properties (lower abrasiveness, greater elasticity, lower adhesion and greater resistance to traction). The addition of mineral loads such as kaolin helps to obtain the required characteristics (e.g. abrasion resistance, improved mechanical properties, etc.).

The highly laminar characteristics of kaolin particles provide excellent properties when incorporated into compounds for tire interior coatings.

We have different names of kaolins and micas for this market:

Product Denomination Industrial use
CAOLIN G-35M Rubber
MICAVI M-20, M-45, M-150 Tires


It is a mineral of natural origin, whitish appearance, clay, inert, of great thermal resistance, used in many sectors as filler or as an excipient, which is part of the group of industrial minerals. It is distinguished from other clays mainly by its whiteness, whiteness and easy dispersion in water and other liquids.

Moscovite Mica

Moscovite Mica

It is a mineral belonging to a large group of micas, alumina silicates, in particular with presence of potassium, high thermal resistance, dielectric and considerable aspect ratio, which gives it highly appreciated properties.
