Product Description

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.

  • Low oil absorption

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%.
