Expanded Perlite

Expanded Perlite is an internal honeycomb structure of the white granular material made by preheated, baked and expanded perlite ore. Principle is: By preheating,fire,rapid heating(1000? above),then the moisture vaporizing,the crushed special size ore is expanded in softened ore to be porous structure,become original 10-30 times.
