Hollow Glass Cenospheres 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 is in Between 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; oil and gas field mining industries can produce high-strength low-density cement slurry and low-density by using its high compressive and low density properties Drilling fluid.

Hollow Glass Microsphere can be widely used in products which have high requirements for looks and colors.
Low density: The density of Hollow Glass Sphere is about one tenth of the density of traditional filler particles. After filling, it can greatly reduce the basis weight of the product, replace and save more production resins, and reduce product costs.

Heat insulation, sound insulation, low water absorption: The inside of the Hollow Glass Sphere is a thin gas, so it has the characteristics of sound insulation and heat insulation, and is an excellent filler for various heat preservation and sound insulation products. The thermal insulation properties of Hollow Glass Microspheres can also be used to protect products from thermal shocks caused by alternate changes between rapid heating and rapid cooling conditions. The high resistivity and extremely low water absorption make it widely used in the processing and production of cable insulation materials. mostly used as heat insulation paints and coatings, automotive sealants.
