Product Description
Hollow glass bubbles, also known as glass microspheres or glass beads, are tiny, lightweight spheres made of glass. They are typically between 10 and 300 microns in diameter, which is roughly the size of a grain of sand.
The glass bubbles are created by heating a mixture of glass and a blowing agent, which causes the glass to expand and form small spheres. The blowing agent is then removed, leaving behind the hollow glass bubbles.
Glass microspheres are usually between 1 and 1000 micrometers in diameter, with hollow glass microspheres typically ranging from 10 to 300 micrometers. Hollow spheres are used as lightweight fill in composite materials such as syntactic foam and lightweight concrete.
Key Applications
- Automotive Industry: Used to manufacture lightweight parts and components, improving fuel efficiency
- Marine Industry: Used in lightweight composites for boats and submersibles
- Adhesives and Sealants: Improves mechanical properties and reduces shrinkage
