1. 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.

2. With organic modification (lipophilic) surface
Hollow glass beads are easy to wet and disperse, and can be filled in most thermosetting thermoplastic resins, such as polyester, epoxy resin, polyurethane, etc.

3. High dispersion and good liquidity
Since 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 this kind of small microbeads are isotropic, so there is no inconsistency in the shrinkage rate of different parts due to orientation, which ensures the dimensional stability of the product and does not warp.

4. 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 preservation and sound insulation products. The thermal insulation properties of hollow glass microspheres can also be used to protect the product from the thermal shock caused by the alternating between rapid heating and rapid cooling conditions. High specific resistance and extremely low water absorption make it widely used in the processing and production of cable insulation materials.

5. Low oil absorption
The particles of the sphere determine that it has the smallest specific surface area and low oil absorption. The amount of resin can be greatly reduced during use, and the viscosity will not increase much even under the premise of high addition, which greatly improves the production operation Conditions can increase production efficiency by 10% to 20%.
