Expanded Perlite

Perlite are siliceous volcanic rocks which are available in only numbered countries  worldwide. Perlite’s unique property is expansion in its specific volume in 35 times when heated up to softening point. ( 850 - 1150ºC).  

This expansion period can be reached by the help of water in rough mineral. If perlite mineral is heated more than 850° C (16000° F), water starts to evaporate and that cause expansion of rock.

 Small glass pieces brings unique lightness and physical properties of perlite.

Perlite means pearl stone and it is glassy volcanic rock with different colors from gray to black tones. Perlite is called as UNPROCESSED PERLITE ORE after it is extracted from the quarry.  

Crushing perlite ore in desired dimensions and sizing them by sieving is named as CRUSHED AND SCREENED PERLITE.

EXPANDED PERLITE is the form of perlite products which lost its content water when it is heated to the softening point and it has a characteristic to be expanded up to 35 times from its original volume.
