Hollow glass microspheres size H20-H60 for thermal insulation
coatings
Description of hollow glass microspheres:
Hollow glass microspheres is also called hollow glass beads, it is
hollow and tiny spherical materials containing inert gas in it.
It is hollow particle with unique and stable properties. And has
the advantages of light weight, large volume, low thermal
conductivity, good dispersion, good fluidity and great stability.
In addition, it also has excellent properties such as insulation,
self-lubrication, sound insulation, non-water absorption, corrosion
resistance, radiation protection, and non-toxicity. Due to its
unique hollow structure, physical and mechanical properties and its
stable chemical properties, as a non-metallic material additive, it
is non-toxic, colorless and tasteless, and has a wide range of uses
as filler agent and lightening agent.
Applicable for thermal insulation coatings, solid floating
materials, oilfield cementing mud and drilling liquid, and 5G board
modified plastic, etc....

Properties of hollow glass microspheres:
Color: pure white.
It can be widely used in products that require appearance and
color.
- Light weight and large volume
The density of hollow glass beads is about one tenth of the density
of traditional filler particles. After filling, it can greatly
reduce the basis weight of the product, replace and save more
production resins, and reduce product costs.
- High dispersion, good liquidity
Because hollow glass beads are tiny spheres, they have better
fluidity in liquid resin than flake, needle or irregular shape
fillers, so they have excellent mold filling performance. What's
more important is that the small microbeads are isotropic, so there
will be no inconsistency in the shrinkage rate of different parts
due to orientation, and the dimensional stability of the product is
guaranteed without warping.
- Heat insulation, sound insulation, insulation, low water absorption
The inside of the hollow glass beads is a thin gas, so it has the
characteristics of sound insulation and heat insulation, and is an
excellent filler for various heat insulation and sound insulation
products. The thermal insulation properties of hollow glass beads
can also be used to protect the product from the thermal shock
caused by the alternating between rapid heating and rapid cooling
conditions. The high resistivity and extremely low water absorption
make it widely used in the processing and production of cable
insulation materials.
The particles of the sphere determine its smallest specific surface
area and low oil absorption. During use, the amount of resin can be
greatly reduced, and the viscosity will not increase much even
under the premise of high addition, which greatly improves the
production and operating conditions. Increase production efficiency
by 10%-20%.
Application of hollow glass microspheres
Hollow glass microspheres is a product filler and lightening agent
in paint coatings, rubber, modified plastics, glass fiber
reinforced plastics, artificial stone, putty and other industries;
the oil and gas field mining industry can produce high-strength
low-density cement slurry and low-density by using its high
compressive and low-density properties Drilling fluid.
