Perlite - 325 Mesh Granular | White Color, High Porosity, Chemical Composition 70-75% Sio2, Ideal For Coating And Painting

We are Making and Exporting Perlite For Coating 325 Mesh in Tianjin, China.Perlite is a sort of nature glass volcanic ore with 2%-5% combined water inside Which is formed when acid volcanic lava flow into lakes or oceans and cool rapidly.
When perlite ore is expanded, the internal microporous structure makes it has low
density, good air permeability and water resistance, so perlite is widely used in
horticulture and agriculture etc.
