Expanding glass microspheres are an inorganic glassy mineral material, processed through a multi-stage silicon carbide electric heating tube production technology. They are irregularly spherical particles with a porous cavity structure inside, a vitrified sealed surface, smooth luster, and stable physical and chemical properties. They possess excellent characteristics such as light weight, thermal insulation, fire resistance, resistance to high and low temperatures, anti-aging, and low water absorption. They can replace traditional lightweight aggregates such as fly ash floating beads, glass microspheres, expanded perlite, and polystyrene beads in various applications. They are an environmentally friendly, high-performance new type of inorganic lightweight thermal insulation material.
