Vermiculite
With the process of removing sand and impurity, crashing, filtrating, vermiculites become exfoliated, they can be divided into different sizes: 0-1mm, 1-2mm, 2-4mm, 1-3.5mm, 3-5mm, 4-6mm and so on, we can produce many sizes as clients required. There are two kinds of vermiculite in our country golden vermiculite and silvery vermiculite, they have different chemical components.
Golden vermiculite

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.
