Vermiculite Concentrates:

Vermiculite is one of the world’s most unique minerals. A hydrated Magnesium Aluminum Silicate, it is light weight, inorganic (incombustible), compressible, highly absorbent and non-reactive and is used in thousands of applications including potting soils and grow mixes.
Vermiculite is used in thousands of applications from potting soils, light weight concrete, fire protection construction materials, intumescent applications, as a packaging material for the safe shipment of hazardous liquids, texturizers in paints and coatings, and most recently as nanocomposites for films, coatings and barrier applications. When subjected to heat vermiculite has the unusual property of exfoliating or expanding into worm-like pieces.
This characteristic of exfoliation, the basis for commercial use of the mineral, is the result of the mechanical separation of the layers by the rapid conversion of contained water to steam.
The increase in bulk volume of commercial grades is 8 to *2 times, but individual flakes may exfoliate as many as *0 times. There is a color change during expansion that is dependent upon the composition of thevermiculite and furnace temperature.
The bulk density of crude vermiculite or vermiculite concentrate is in the range of *******0 kg/m³ and exfoliated or expanded vermiculite is in the range of *****0 kg/m³
With such prominent characteristics as being fireproof，heat insulating，sound and moisture absorbing，non-toxic，lightweight and disease free. It is widely used in construction，chemical industry，petroleum，electronics，light industry，environmental protection and as a medium of agricultural chemical products etc.
