PERLITE, AGRIPERLITE 0/3 mm (about 13,5 Kg - 150 lt).

Agri-perlite is an inorganic and stable, chemically inert, sterilized product.

Perlite is a specific variety of effusive volcanic rock included in the range of rhyolites and dacites which has the exceptional property of expanding up to 20 times its original volume.

Under the effect of the high temperatures (between 850 and 1,000°C) reached in contact with a flame in the expansion furnace, the water contained in the granule dissociates and turns into steam, swelling the surrounding glass walls and causing the characteristic increase in volume of the granule itself.
This irreversible process determines the formation of micro-cavities which give expanded perlite its extraordinary insulating power.

Furthermore, expanded perlite cannot be attacked by microorganisms due to its sterility and inorganic nature and does not activate the development of microbiological pollutants.
