Vermiculite is a mica mineral and has a laminar structure. When heated the vermiculite may expand to about 15~25 times its original volume. The product formed has a golden luster and density of only few kilogram per cubic meter.

It is a lightweighted sound resistance material and low thermal conductivity (normal about 0.0047~0.051Wm.K), lightweight and chemical stable. No toxic and good for constant temperature, resistance, sound absorbant and vibration resistance. Common suitable temperature is -30~1000℃ (The fusion point is about 1370℃). It is non-inflammable and humidity absorption. Well for mill factory, power supply, petrol manufacture and building construction. It is also good conditioner for planting of the landscape works.
