Specification

Product Description

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

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, 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.

Application Area

a. lightweight cement, low-density oil well cementing slurry & low-density drilling fluids additive.
b. low-density FRP(fiberglass-reinforced plastic), SMC, BMC composites.
c. Nylon, PA, PA6, PA66 for reducing weight.
d. low-density adhesives & sealants.
e. heat insulation paints and coatings.
f. Construction (reducing warpage/shrinkage).
g. Insulation and Buoyancy.
h. artificial marble.

Our hollow glass microspheres can be used in paint and coatings, construction sealant, rubber, plastic, FRP, artificial stone, putty and other products as filler and weight-reducing agent. The glass bubbles can also be used to produce high-strength, low-density cement slurry and low-density drilling fluid in oil and gas extraction industry. more and more industries now trying to testing the hollow glass spheres as additives to improve their products' properties.
