Product Description
Hollow glass bubbles (HGBs) are engineered microspheres used in oil well cementing to enhance cement properties and performance. Their unique combination of low density and high strength makes them ideal for demanding applications.
Key Applications
- Thermal insulation: Reduces thermal expansion and contraction, minimizing cracking risks in wellbores
- Fluid loss control: Decreases cement permeability to improve seal integrity
- Weight reduction: Maintains strength while significantly reducing cement density
