Hollow Glass Microspheres
Also called bubbles, microbubbles, or microballoons, are typically made out of borosilicate-sodalime glass blend formulation and provide the benefits of low density, high heat and chemical resistance. The walls of glass microspheres are rigid and typically have the thickness of 10% of the diameter of the sphere. Spherical microparticles are currently available in a broad range of densities from as low as 0.06g/c3 to as high as 0.80g/c3 and sizes from 5um to 180um in diameter. The crush strength of the hollow spheres is determined by the thickness of the walls and, as expected, the higher the sphere density the higher the crush strength. The lightweight hollow glass spheres are chemically stable, noncombustible, nonporous, and have excellent water resistance.
Hollow glass microspheres are also offered with conductive coatings. Conductive coating with optimized thickness provides spherical particles with good conductivity and shielding properties while maintaining the weight-saving benefit associated with hollow-core low-density materials. These conductive microbubbles are suitable for use in military applications, biotechnology, medical devices, electronics, and other specialty industries.
Specification
Product Description
Hollow Glass Microspheres is a kind of hollow spherical powdered ultralight inorganic nonmetallic materials.
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.
