Hollow Glass Microsphere Hollow glass Microsphere is a kind of hollow spherical powdery ultra-light inorganic non-metallic material. Its true density is 0.15-0.65g/cm³, particle size is 2-120μm, wall thickness is 1-2μm, and its compressive strength ranges 3-125MPa, it has the characteristics of light weight, large volume, low thermal conductivity, high compressive strength, and good fluidity. It is a product filler and lightening agent in paint coatings, rubber, modified plastics, glass fiber reinforced plastic, artificial stone, putty and other industries; In oil and gas field mining industries it can be used to produce cement slurry and drilling fluid with properties of high strength, high compressive,low density. Properties: Pure white color, Hollow Glass Microsphere can be widely used in products which have high requirements for looks and colors. Low density, reducing the products’ basic weight obviously after filling. (the density is one out of a dozen of traditional filler particles’ density). Relatively large volume, which can substitute and save more resins, reducing cost. High dispersion and good fluidity, dimensional stability, reduced warpage and shrinkage when used as additives. Heat insulation, sound insulation, mostly used as heat insulation paints and coatings, automotive sealants. In addition, corrosion resistant, fire resistant, non-conducting.
