2. Product Overview
Vermiculite is a naturally occurring mineral that belongs to the mica group. It is a hydrated aluminosilicate of iron and magnesium with a layered structure. When heated to high temperatures (typically 800°C–1100°C), vermiculite exfoliates or expands, forming lightweight, accordion-like particles with high porosity and excellent thermal insulation properties. This process is known as expansion, and the resulting material is called expanded vermiculite.
Iranian expanded vermiculite is characterized by its low density (150–400 kg/m³), high moisture absorption capacity, excellent thermal resistance, and chemical inertness. It is neutral in pH, rot-proof, and fire-resistant, making it suitable for a wide range of applications. In agriculture and horticulture, vermiculite is used as a soil amendment to improve aeration, water retention, and nutrient holding capacity. In construction, it is used as a lightweight aggregate in concrete and plaster, and as insulation in walls and ceilings. In brake pads, vermiculite serves as a friction modifier and thermal insulator. In fireproofing, it is used in fireproof paints and concretes to enhance fire resistance.
