Introduction of Perlite:
Perlite is a glassy rock formed by the rapid cooling of acidic lava from volcanic eruptions. After heating, it can be expanded to 12-15 times. lts characteristics are very light, thermal insulation, sound insulation, strong absorption etc. It is used in new building materials, petroleum chemistry，metallurgy casting，agriculture, food filter, and environment protection.
Size and Application of perlite sand
Size | Application |
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. |
