Hollow Glass Bubble Description
Hollow glass bubbles provide excellent buoyancy properties, with a typical buoyancy of around 200 kg/m³. This makes them an ideal choice for marine and offshore applications where buoyancy is critical. It provides a cost-effective and customizable solution for a wide range of buoyancy applications, from marine floats and buoyancy aids to subsea equipment and offshore oil platforms.
Hollow Glass Bubbles Applications
- Marine floats: Used to mark the location of underwater structures, such as pipelines and cables.
- Buoyancy aids: Used to manufacture life jackets and buoyancy vests, providing excellent buoyancy properties to keep wearers afloat.
