Product Name: Expanded 2-4mm Vermiculite for Horticulture Insulation Fireprof Model NO.: LJ-2001 Certification: CE, SGS Application: Refractory Bulk Density: 110-150kg/M3 pH: 7-9 Trademark: LJ Transport Package: 100L/Bag 730bag/40hq Specification: 1-2mm2-4mm 3-6mm 4-8mm Origin: China HS Code: 6806200000 Product Description    Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. It is found in various parts of the world, vermiculite is basically a hydrated phlogopite mica which has the remarkable ability to expand to many times than its original volume when heated at 850 °C.Vermiculite is most widely used in its exfoliated form. The concertina-shaped granules of exfoliated vermiculite are non-combustible as well as being insoluble in water and all organic solvents.
