Product Description

Hollow glass bubbles, also known as glass microspheres or glass bubbles, are tiny, hollow spheres made of glass. They are typically between 10 and 200 micrometers in diameter and are used in a variety of applications due to their unique properties.

One of the main advantages of hollow glass bubbles is their low density. They are much lighter than other fillers such as sand or talc, which makes them an ideal choice for weight reduction in composite materials. They are also highly compressible, which allows them to absorb stress and reduce the overall weight of a material.

Key Applications

Concrete: Used as a lightweight additive to reduce weight and increase strength in precast concrete, lightweight concrete blocks, and bridge decks
Plaster and stucco: Used as a lightweight filler to reduce weight and improve workability in interior/exterior walls, ceilings, and decorative features

Frequently Asked Questions

Can you tell me more about packaging options for Hainuo HGBs?

We offer carton and ton bag packaging options with dimensions based on model and density. Customers can discuss custom packaging requirements with our team.

What are Hainuo Technology's achievements in the HGB field?

Founded in 2011 with government-backed research, we've achieved significant technological breakthroughs and been awarded "High-Tech Enterprise" status and "Outstanding Enterprise in Shanxi province". Our products are used in major national projects by CNPC and CNOOC.

What safety precautions should be taken when handling HGBs?

Work in ventilated areas, handle packages gently to minimize dust, and use protective equipment (gloves, safety glasses) if sensitive to dust.

What are the advantages of using hollow glass bubbles?

They enhance thermal insulation, fluidity, stiffness, strength endurance, and chemical resistance while reducing weight and production costs.

What is Hainuo's annual production capacity?

Current capacity is 15,000 tonnes/year, expanding to 35,000 tonnes/year by 2026 with new production lines.

How should hollow glass bubbles be stored?
