Product Detail
The exfoliation process is carried out commercially by passing crude vermiculite through a furnace chamber in a controlled manner. The crude vermiculite then expands at right angles to the cleavage planes, producing concertina-shaped particles many times their original volume.Exfoliated vermiculite size ,includes 0.3-1mm1-3mm1-2mm2-4mm2-3mm3-5mm3-6mm4-8mm6-8mm,special size can be done as per customer’s demands .
