Hollow Glass Bubble Description
Buoyancy materials with hollow glass bubbles are lightweight, which makes them easier to transport and install. This can result in cost savings in terms of transportation and labor costs. Besides, hollow glass bubbles are strong and durable, making them an ideal material for buoyancy applications. They can withstand harsh marine environments and resist degradation from water and UV exposure.
Hollow Glass Bubbles Applications
- Marine buoys and floats: Used to create lightweight and durable buoys and floats for marine applications, such as navigation aids and mooring buoys.
- Offshore oil and gas structures: Used to provide buoyancy to offshore oil and gas structures, such as pipelines, risers, and platforms.
- Underwater equipment: Used to provide buoyancy to underwater equipment, such as remotely operated vehicles (ROVs), diving equipment, and oceanographic instruments.

Can you tell a brief progress history of Hainuo Technology and what specific achievement and merits rewarded in the HGBs field?
The Hainuo Technology's history can trace back to 2010s, officially founded in 2011. The company was backed by research from several renowned government-owned institutions and authority agencies, achieving tremendous technology breakthrough in a short time and now ranks in the global list of most competitive manufacturers.
Hainuo Technology has been rewarded several significant national prizes and honors including the title "High-Tech Enterprises", "Outstanding Enterprise in Shanxi province". Hainuo Glass Bubble is applied in many significant China national oil and ocean projects by CNPC and CNOOC.
What protection steps should users take when removing HGBs exterior package?
Before unpackage, please place cartoon box or ton bags in spacious area with effective ventilation conditions, then gently and slowly remove packaging bands. To better mitigate dust emission, lift and down of bags should be controlled within slight vibration and shake.
Users should mind the dust emission during unpackaging. For users with allergic symptoms to dust, safety protection kits including safety eyeglass and gloves are suggested.
What are advantages of using hollow glass bubbles?
Hollow glass bubbles can be applied as a lightweight filler in various industries, enhancing products' Thermal Insulation, Fluidity & Stiffness while improving original strength endurance and Chemical Resistance.
What are some common applications of hollow glass bubbles?
Hollow Glass Bubbles cover wide application in Aerospace, Rubber, Plastic, Marine and Construction industries. HGBs are used as lightweight fillers which improve products performance and effectively reduce original production cost.
What is the range of Hainuo HGBs density and size range?
It varies based on their physical application. The typical density range is 0.11-0.606 g/cm³ and the size range from 10um to 115um.
Are Hollow Glass Bubbles products environmental friendly?
Hollow Glass bubbles are environmental friendly product as they are made from natural sand and will not cause any side effect to users or environment. They are recyclable and reusable. Hainuo Technology stresses environmental responsibility throughout production.
Can Hollow Glass Bubbles be used in 3D Printing?
Yes, hollow glass bubbles can be added to 3D printing materials to reduce weight and improve strength. They can also improve printability and reduce warping.
Can Hollow Glass Bubbles be used in Concrete?
Yes, they can be used as lightweight aggregate in concrete to reduce weight and improve thermal insulation and fire resistance. They also improve workability and durability of concrete.
