Floating beads for industrial raw material filling

Hollow Glass Microspheres is a type of hollow silicate-aluminium microsphere refined from fly ash in thermal plant, also called cenosphere. The main component are silicate and aluminum oxide. It has very good heat stability, corrosion resistance, strength, insulation property, low thermal conductivity, non-toxic, low moisture absorption, good chemical stability. It has low density, combined with the inert property. It is widely used in oil drilling and insulation, plastic, rubber, coating, auto and construction industries.
