DETAILED INTRODUCTION

Perlite Sand


Size and Application of Perlite sand


8-12 mesh
 12-18 mesh
 18-20 mesh

After expanding, it is widely used as the materials of keeping warm and heat insulation in the field of construction.  

20-30 mesh
 30-50 mesh

After expanding, it can be used as covering agent and deslagging agent in the industry of casting steel.

50-70 mesh

After expanding, it can be used as the filtering agent in the field of beer and medicine, and the insulation for cryogenic tanks of oxygen machine.
