Muscovite mica is a natural mineral composed of aluminum, silicon, and potassium, belonging to the phyllosilicate family. It is characterized by its layered structure and perfect cleavage. In addition to its brilliance and whiteness, it offers notable mechanical and physical properties. Excellent electrical insulation and low thermal conductivity make it particularly valued for thermoelectric and thermomechanical applications.
At CAVISA's facilities, mica is extracted and processed into more than 40 different particle sizes, marketed under the MICAVI brand across many sectors.
Mica is widely used in the production of extinguishing powders, fireproof, and refractory coatings, leveraging its fire resistance and heat tolerance properties. Furthermore, it is appreciated in the production of industrial and residential paints and coatings as a technical filler that enhances aging resistance, provides a barrier effect against gases and corrosive agents.
In the plastics industry, finely micronized mica imparts rigidity, dielectric properties, and resistance to weathering and wear to thermoplastic polymers. It reduces deformation and adds sound-absorbing properties.
In cosmetics, CAVISA mica is extensively used as a filler in natural makeup formulations, such as face and eye powders, where it modifies coverage, opacity, and adhesion to the skin.
