1. The product is a new heat insulation material.
2. The product is expanded by electric furnace in high temperature, and the surface of expanded perlite appears to be micro- circular particles with glass-based shell. The pore is closed and the interior is hollow structure basically.
3. With such prominent characteristics as high strength, low water absorption, easy to disperse, it can improve the fluidity of mortar, and is widely used as lightweight aggregate of insulated mortar for interior and exterior wall, decorative board andinsulation board.
4. Meanwhile, it can be used instead of drift beads partly. It can also be used in construction, metallurgy, industrial kilns。
