Product Description

Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above **0.C, the water flashes into steam, and the flakes expand into accordionlike particles. This process is called exfoliation, or expansion, and the resulting lightweight material is chemically inert, fire resistant, and odorless. We expand and sieve well-selected golden & silvery vermiculite with advanced equipment in our own factory,which is located in Hebei Province China. We can process various specifications of vermiculite as per customers' request with large quantity,low density and impurity.
