The perlite is an inorganic, stable, chemically inert, sterilized product. Perlite is a specific variety of extrusive volcanic rock in the range of rhyolites and dacites and has the unique property to expand up to 20 times its original volume. Under the effect of the high temperatures (between 850°C and 1000°C) reached at the contact of a flame in the furnace of expansion, the water contained in the granule is transformed into steam, inflating the walls surrounding vitreous and causing the characteristic increase in volume of the granule itself. This process, irreversible, leads to the formation of micro-cavities which give the expanded perlite its extraordinary insulating power. The expanded perlite cannot, moreover, be attacked by microorganisms for its sterility and inorganicity and stops development of microbiological pollutants.
