3.Other sizes could be produced as requested.
DETAILED INTRODUCTION
Perlite Sand
Size and Application of Perlite sand
8-12 mesh | After expanding, it is widely used as the materials of keeping warm and heat insulation in the field of construction. |
20-30 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. |
