Expanded Vermiculite is a natural mineral that belongs to the mica group, primarily composed of iron and magnesium silicates. Its extraction takes place in open-pit mines, where it is processed to remove rocks and impurities, obtaining a mineral classified by size.
Subsequently, the Expanded Vermiculite undergoes a thermal treatment known as exfoliation, which allows the mineral to expand up to 12 times its original volume. This process highlights key characteristics that make this material an ideal option for multiple applications.
Properties of Expanded Vermiculite
Light and clean: Perfect for use in sensitive environments.
Thermal and acoustic insulation: Provides excellent insulation properties.
Non-combustible and insoluble in water: Resistant to high temperatures and humid conditions.
Absorption capacity: Ideal for applications that require managing liquids.
Uses of Expanded Vermiculite
Industry
Used in the creation of mortars and refractory elements, as well as passive fire protection. In metallurgy and foundry, it acts as a cushioning for liquid metals.
Agriculture
It is ideal for tray covers in seedbeds, maintaining temperature and humidity. Additionally, when mixed with organic substrates, it improves aeration. In animal nutrition, it facilitates nutrient loading in feed additives.
Construction
Functions as a basic ingredient in the production of lightweight projection plasters and in the creation of vermiculite boards or panels, providing fire resistance and thermal stability.
The versatility of Expanded Vermiculite makes it an essential product for various industries.
