Perlite Board

Production Technical:

Closed cell perlite is a new perlite product, it is cobbing with a certain granularity will expand inside to outside after reaching a certain temperature under scarped heating of vertical electric furnace, and then the surface of expanded granular gets quick high-temperature vitrification, and becomes continuous vitrescence surface after cooling, inside it maintains a complete multi-pore and hollow structure. The specific production way of this product insures the purity of natural inorganic chemical composition of perlite.
