product information :
Vermiculite, chemical formula M g × (H2O) [Mg3 × (AlSiO3O10) (H2O)], is a magnesium water inclouded aluminum silicate
secondary metamorphic minerals of layered structure. It likes mica in form, and usually come from weathered or hydrothermal
alterated black (gold ) Mica. It will present a deflection shape after heat expansion and water loss, liking a leech pattern in form ,
so it gets the name vermiculite .
Vermiculite features
Raw vermiculite will be expanded to many times when heated at 850-1100 °C,
poisonless, odorless , corrosion-resistant, Non-combustible , natural refractory properties , Good thermal insulation , low density , Heat-resistant ,sound-proofing .fire-proofing etc .

Applications
Raw vermiculite is widely used for Foundary Insulation and Steel Industry
Expanded vermiculite is used in various industries as a packing material due to its highly absorbent nature. It is also a lightweight
aggregator for plaster, proprietary concrete, compounds, fire stop mortar and cementious spray fireproofing. It can also be used as
loose fill insulation and can be molded into shapes, bonded with cement and other bonding materials for insulation, refractory
insulation, fireproofing of structural steel and pipes industries. Exfoliated vermiculite is also widely used as a component of the
interior fill for fire stop pillows, and is also used in commercial hand warmers.
Vermiculite is used for Horticulture :lawn of golf,seed preservation agent,soil conditioner ,wetting agent,plant growth
substance,feed additive ,any other applications
