Hainuo Hollow Glass Microsphere (HGM) is a kind of hollow spherical powder which is inorganic and non-metallic. It is a new kind of lightweight material with wide applications and excellent properties. Its true density is 0.15-0.60 g/cm and particle size is between 10-130μm. Due to its advantages of light weight, large volume, low thermal conductivity, high compressive strength, good fluidity and stable chemical properties, Hollow Glass Microsphere is widely used in coatings, rubber, plastics, glass steel, artificial stone, atomic ash, emulsified explosives and oil and gas field mining industry products.
