1. Product Description
Hollow glass microspheres, a kind of ultra-light inorganic and
non-metallic powder, have been developed into a new type of high
performance lightweight material and widely applied in recent
years. It will be the main direction for new-type compound
materials in the 21st century.
Its true density is 0.12-0.70 g/cm 3 ; particle size is 2-120μm;
Due to its excellent advantages of light weight, low density,
higher compressive strength, improved dispersion and liquidity, it
can be used as filler in painting, rubber, plastics, FRP,artificial
stone, putty, exploitation of oil and gas and other materials.

4. Properties of Hollow Glass Microsphere Bubble
1)Color and shape: pure white flowable powder.
2) Low density, reducing the products’ basic weight greatly after
filling.
3) High loading volume, which can substitute and save more resins,
reducing cost accordingly.
4) High dispersion and good fluidity.
5) Dimensional stability, reduced warpage and shrinkage.
6) Heat insulation, sound insulation, mostly used as heat
insulation paints and coatings, automotive sealants.
7)Corrosion resistant, fire resistant, non-conducting.
8)Stable chemical properties.
5. Application of Hollow Glass Microsphere
Hollow glass bubbles can be used in marine resource development,
aerospace, vehicle lightweighting, 5G communications, oil and gas
exploitation, adhesives, coatings, wood substitutes, rubber, sports
equipment, resin grinding wheels, emulsion explosives, artificial
stone and other industries.
