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 .

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.
