gardening perlite/ foundry perlite

  Perlite comes from volcanic lava. For expanded perlite has low density and low heat conductivity characters. It is a kind of amorphous, glassiness volcano that contains crystalline water inside.     Size: 1,Raw perlite, 18-20mesh,20-30mesh,35-50mesh,50-70mesh,60-120mesh,120-200mesh,325mesh etc. 2,Expanded perlite, 0.01-0.2mm,2-3mm,0.5-1.5mm,1-4mm,2-5mm,3-6mm etc.  
  Bulk Density, For size of 0.5-2MM,1-3MM,2-4MM,3-6MM, the bulk density is around 55-80KG/M3. For filter aid grade, the bulk density is 110KG/M3,130KG/M3,150KG/M3.
