DFL Vermiculite
Vermiculite is the generic name for laminar, hydrated ferromagnesian-Aluminum-Silicate minerals that resemble mica in the crude form. It has a great number of industrial uses by virtue of its expansion behavior on heating.
When heated rapidly to 900-1,000 D.C, its interlaminar water turns to steam and causes the minerals layers to exfoliate or sepreate into worm-like pieces. This forms a material with Lower Density, Excellent Insulation properties, Good Absorption, Iron Exchange Capacity, Chemically Stable and Non-toxic.
The above properties make it widely used in Construction, Agriculture and Horticulture and Industrial application.
