Hollow Glass Microspheres
Hollow Glass Sphere is a kind of hollow spherical powder ultra-light inorganic non-metallic material, particle size is 2-120μm, wall thickness is 1-2μm, compressive strength is between 300-30000psi, and it has the characteristics of light specific weight, large volume, low thermal conductivity, high compressive strength, good fluidity, etc. It is a product filler and reducing agent for paint coating, rubber, modified plastic, glass fiber reinforced plastic, artificial stone, putty and other industries. Oil and gas field mining industry can produce high strength and low density cement slurry and low density drilling fluid by using its high compressive and low density properties.
The Properties of Hollow Glass Microsphere
Pure white color, Hollow Glass Microsphere can be widely used in products which have high requirements for looks and colors.
Low density
The true density of hollow glass sphere is about one-tenth of that of traditional fillers, and this property can reduce the specific gravity of the filled product.
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.
