High-Performance HGMs for Green Building and Composite Materials
With low density, high compressive strength and spherical structure, Hollow Glass Microspheres are widely used in construction materials, especially green building materials and composite materials. HGMs can reduce the overall density of finished products, improve thermal insulation, sound insulation, dimensional stability and surface finish.
As an essential functional filler, HGMs optimize material properties and cut production costs for fiberglass reinforced plastics, artificial marble, tooling board, polyester furniture and lightweight GRP core materials.
- Reduce composite and finished building component density.
- Improve thermal resistance and sound absorption.
- Reduce shrinkage and warpage in panels and construction parts.
- Upgrade surface flatness, smoothness, coating and decorative outcomes.
- Enhance fluidity and uniform filling during production.

Engineer Selection Guide for Construction Material HGMs
The selection of HGMs for construction materials depends on density, particle size distribution, compressive strength, surface modification and oil absorption. These indicators directly influence weight control, processability, microsphere survival rate, interfacial bonding and resin consumption.
| PARAMETER | ENGINEERING FUNCTION |
|---|---|
| Density | Control component weight to achieve lightweight design. |
| Particle Size Distribution | Improve fluidity and uniform filling effect. |
| Compressive Strength | Ensure high survival rate of microspheres during mixing and processing. |
| Surface Modification | Strengthen interfacial bonding with resin or adhesive to optimize surface properties. |
| Oil Absorption | Cut resin consumption and lower overall material cost. |
How to Choose the Right HGM Grade?
Start from the construction material system and processing route, then confirm the target density, required surface quality, strength retention and resin cost target.
For artificial marble: focus on density, impact resistance and surface appearance.
For tooling board: focus on CNC machining efficiency and dimensional accuracy.
For polyester furniture: focus on resin saving, smoothness and rigidity.
For repair putty: focus on adhesion, spreading fluidity and sanding behavior.

Construction Materials Do's and Don'ts
Recommended Practices
✅ Define the target product first: artificial marble, tooling board, furniture board, putty or GRP core.
✅ Match density and particle size distribution to the required flow and filling behavior.
✅ Confirm compressive strength before high-shear mixing or machining routes.
✅ Test surface finish, curing behavior, sanding loss and final part weight together.
Common Selection Mistakes
❌ Choosing the lowest density grade without checking breakage rate.
❌ Ignoring oil absorption when resin cost is a key target.
❌ Using one grade for artificial marble, tooling board and putty without separate validation.
❌ Judging only raw material cost instead of finished product rejection rate and processing efficiency.
