Raw material for vermiculite board
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.
We DFL Company, as the only Director member of TVA (The Vermiculite Association) in Asia, running ISO9001-2008 quality management system, dealing Non-metallic minerals products over 20 years more.
