Non-asbestos raw/unexpanded/crude vermiculite
We engaged in manufacturering &supplying Raw vermiculite in difference size 0.3-1mm 0.5-1.5mm 1-2mm 1.5-2.5mm 2-4mm 0.3-0.6mm ) with 5.5-10times expansion ratios ,
special size can be produce as customer's requirements .
1.Vermiculite
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.
