Some of the Important Applications

Raw Vermiculite is extensively used for ladle topping in foundry industries. Exfoliated vermiculite is used in the Friction Brake Linings Market, Packing Industry, High Temperature insulation, Loft insulation, Sound Insulation, Various Construction Products, Animal feeds, Horticulture and many other Industrial Applications. The cation exchange properties of vermiculite, and its layered structure and surface characteristics are utilized in products such as fire resistant coatings and gaskets.

Toxicology

Non-Toxic

Important Properties

The water content, typically around 10%, gives Vermiculite the unusual property of expanding (termed Exfoliation) when heated rapidly, due to the interlaminar generation of steam. Vermiculite is a safe inert material, light in colour.  When heated it expands up to 30 times its original volume converting dense flakes of or into lightweight, porous granules containing innumerable minute air layers.

Exfoliated vermiculite is light and clean to handle, has a high insulation value, acoustic insulating properties and will absorb and hold a range of liquids.  The granules are non-combustible and are insoluble in water and organic solvents.
