Product Description
Vermiculite is a member of the phyllosilicate minerals, similar in appearance to mica. Vermiculite, distributed throughout the world, is basically a hydrated mica that has a remarkable ability to expand to many times its original volume when heated at 850 -1100°C.
Raw vermiculite is composed of gold and silver vermiculite. After careful classification, there are many specifications, including 0.3-1mm1.5-2.5mm0.5-1.41mm1-2mm2-4mm3-6mm4-8mm, etc.

exfoliated vermiculite
The commercial exfoliation process is carried out by passing coarse vermiculite through a furnace chamber in a controlled manner. The coarse vermiculite then expands at right angles to the cleavage plane, producing organ-shaped particles that are many times their original volume.Expanded vermiculite size, including 0.3-1mm1-3mm1-2mm2-4mm2-3mm 3-5mm3-6mm4-8mm6-8mm, special size can be made according to customer requirements.
