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.

We offer standard packaging options in cartons and ton bags. Package dimensions vary based on model and density. Customers can discuss custom packaging requirements with our team.
Founded in 2011 with government-backed research, we've achieved significant technological breakthroughs and earned recognition including "High-Tech Enterprise" and "Outstanding Enterprise in Shanxi province." Our products are used in major national projects by CNPC and CNOOC.
Unpackage in well-ventilated areas with minimal vibration to reduce dust. Those with dust allergies should use protective eyewear and gloves. Keep packages sealed when not in use.
HGBs enhance thermal insulation, fluidity, stiffness, strength endurance and chemical resistance while reducing product weight and production costs.
Current annual capacity is 15,000 tonnes, expanding to 35,000 tonnes by 2026 with our second production line.
Store in dry, cool areas away from direct sunlight. Keep packages tightly sealed to prevent particle emission.
