Hollow Glass Bubble Description
The use of hollow glass bubbles in structural sealants can improve their fire resistance properties by reducing heat transfer, creating a barrier to oxygen, providing inertness, and reducing flammability. These benefits help improve the overall safety of structures and reduce the risk of fire-related damage.
Key Applications
- Vibration damping: Improves ability to dampen vibrations, particularly important in machinery and equipment applications.
- Sound insulation: Enhances acoustic performance by reducing noise pollution.
- Reduced shrinkage: Maintains dimensional stability during curing, reducing risk of cracking or deformation.
