Heat-resistant, corrosion-resistant, well-ventilation, water preservation, poisonless, odorless, low hardness, burning-avoidness, lighter
2.Vermiculite production
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 t expand to many times 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. Safe and easy to handle
