Product Description
Hollow Glass Bubble Description: In aviation applications, the pursuit of lightweight and thermal insulation materials while maintaining durability and solidity makes hollow glass bubbles an ideal solution. These additives not only improve acoustical insulation properties but also enhance impact resistance of adhesive materials, reducing risk of damage to aircraft from mechanical stress.
Key Applications
- Lightning strike protection: Improves electrical conductivity in aircraft adhesives, providing conductive paths for lightning currents.
- Thermal management: Enhances thermal conductivity in interface materials and coatings for efficient heat transfer.
