Raw vermiculite is a natural mineral, non-toxic, will expand at high temperature under the action of mineral. It is alternatively rare mineral, which belongs to the portland. The crystal structure is monoclinic, from the shape it looks like mica. Certain granite hydrated vermiculite is generated. The ability of ion exchange vermiculite, its soil nutrition has a great role.Vermiculite can be used as construction materials, adsorbents, fireproof insulation, mechanical lubricant, soil conditioner and so on, a wide range of uses.

Processed Vermiculite
Vermiculite may be milled before or after exfoliation according to the range of particle sizes required. Such milled or ground material may be used for the production of sound-absorbing coatings; Condensation control paints; High performance gaskets and seals and for upgrading the fire resistance of organic foams and other polymer based system. Exfoliated vermiculite can be colored to suit its end use.
