Vermiculite is the geological name given to a group of hydrated laminar minerals which are Aluminium iron – magnesium silicates, resembling mica in appearance. Rock and other impurities are removed from the crude ore which is then crushed and sorted into sizes.

Vermiculite is a safe inert material and is light in color. When heated it expands (exfoliates) upto 14 times its original volume. The exfoliation process converts the dense flakes of ore into lightweight porous granules containing innumerable minute air layers. Exfoliated (expanded) vermiculite is light and clean to handle, has a high insulation value, acoustic-insulating properties and will absorb and hold a wide range of liquids.

These granules are non-combustible, and are insoluble in water and all organic solvents. Expanded vermiculite is easily poured, is light, clean, highly absorbent and provides baffle against impact shock when used for packing.

Exfoliated vermiculite is used in the friction brake linings market, high temperature insulation, loft insulation, various construction products, animal feeds, horticulture and many other industrial applications. Vermiculite with its layered structure and surface characteristics, is utilized in products such as in tumescent coatings and gaskets, the treatment of toxic waste and air-tight packaging of hazardous goods.

0-1 mm
