Expanded vermiculite
Exfoliated vermiculite in the process of high temperature roasting, they can expand many times, and the average density of the expanded vermiculite is about 100-130kg/m3, they have small air separation layer, so they are good construction materials of heat preservation, thermal insulation sound absorption, and corrosion proof, and also industry loading material, coating, anti-fire materials. Expanded vermiculite can extensively used in many industries such as construction, metallurgy, chemical industry, light industry, machinery, electric power, petroleum, environment protection communication, transportation and horticulture
