What is Perlite ?

Chemically, it is an amorphous mineral consisting of fused sodium potassium aluminium silicate. Perlite are siliceous volcanic rocks around whole world. Perlite’s unique property is expansion in its specific volume in 20 times when heated up to softening point.( 850 - 1150ºC) The expansion of Perlite takes place due to the presence of 2 to 6 per cent combined water in Perlite Ore. Combined water vaporizes and creates countless tiny bubbles that create a light weight product and other exceptional physical properties of Expanded Perlite. 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 - its white colour irrespective of the colour of crude Perlite Ore which could be from light gray to glossy black.

Perlite means pearl stone and it is glassy volcanic rock with different colors from gray to black tones. Perlite takes the name of ORE PERLITE from here. Breaking rough perlite in desired dimensions and sizing them by sieving is named as CLASSIFIED PERLITE.

EXPANDED PERLITE is perlite which lost its water because of fire shock applications and perlite with expanded grain volume up to 20 times as a result of this application. Expanded perlite is produced in different grain sizes in accordance to their sectors of usage. Expanded Perlite can be manufactured to weigh as light as 32 kgs./cu.m., making it suitable for many exciting applications.
