The mining of perlite ore takes place in open-pit mines located in volcanic areas in different regions of the world. The ore is milled and sifted in different sizes so that it can be transformed later.
The processed ore is calcined at 1000°C which causes the water molecules inside to evaporate, exploding and expanding up to 20 times its original volume, producing the expanded perlite.
Perlite is a volcanic mineral with a high water molecule content within its structure.
The expanded perlite is a white granular material that is extremely lightweight, the new structure gives it remarkable thermo-acoustic qualities. The countless micropores of dry air in the new structure makes the material behave as a very efficient natural insulator.
The expanded perlite retains the original qualities of the natural mineral, it is chemically neutral, inert to atmospheric agents and the passage of time, non-combustible, non-toxic, insoluble and non-hygroscopic. That makes the perlite as an efficient natural insulation for the construction industry and agriculture.
