Hollow Glass Microspheres is a type of hollow silicate-aluminum 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 automotive coating, Heavy-duty anticorrosive coating, marine protecting coating, adhesive, plastic, rubber, oil drilling and insulation, auto and construction industries.
Application:
Hollow Glass Microspheres is widely used in protecting coating, marine protecting coating, insulating paint, anticorrosive paint, high-temperature fire-resistant paint, architectural paint, car putty, floor paint, putty, plastic, rubber, adhesive, etc.
