Perlite is a volcanic and glassymineral and contains water particles inside its structure.
During the production, perlite is heated up to 800-1200°C at special ovens and due to flash evaporating water particles inside it pops like popcorn and forms a high porosity granular structure. At the end of this process it expands up to 4-20 times of its volume and its density decreases.
Thanks to the porous and volcanic structure of expanded perlite, it can be used in many fields mainly in construction, aggregate, horticulture and filtering.
While its benefits and fields of use are still being discovered, 65% of the reserves of this mineral is in the territory of Turkey.
