Hollow Glass Microsphere H25


Hollow Glass Microspheres is a kind of hollow spherical powdered ultralight inorganic nonmetallic materials.


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 of HGS 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.
