Product Description
Hollow Glass Bubble Description
Buoyancy materials are extensively used in flotation applications for boats, docks, and other structures requiring long-term buoyancy. These materials must support the structure's weight while maintaining buoyancy, durability, and resistance to water and environmental factors.
The addition of hollow glass bubbles reduces material density while maintaining volume, resulting in lighter materials that provide the necessary buoyancy to support structural weight.
Hollow Glass Bubbles Applications
- Oil and gas exploration: Used in buoyancy materials to support equipment and instrumentation in offshore drilling and exploration activities.
- Recreational watercraft: Improves safety and performance of kayaks, canoes, and paddleboards by enhancing stability and control.
