Low thermal conductivity hollow glass microspheres HL15 HL20 HL25 for thermal insulation putty and coatings
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.
