Hollow Glass Bubble 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 Bubbles are spheres of glass manufactured for a wide variety
of uses in researching, Rubber Plastic and various industries.
Glass microspheres are usually between 1 and 1000 micrometers in
diameter, although the sizes can range from 100 nanometers to 5
millimeters in diameter. Hollow glass microspheres, sometimes
termed microballoons or glass bubbles, have diameters ranging from
10 to 300 micrometers.

Hollow Glass Bubbles Application:
1.Oil and Gas Industry:
HGMs can be added to drilling fluids and cement slurries to reduce
their density and improve their thermal insulation properties.
2.Cosmetics:
HGM can be used in cosmetics and personal care products to provide
a lightweight, smooth texture.
3. Marine Industry:
Hollow glass bubbles are used in the marine industry to manufacture
lightweight composites for boats,

FAQ:
Question 1:Can you tell me more package details of Hainuo HGBs?
Answer1: We mainly offer customers package options of cartoon and ton
bags, our HGBs packages varies their dimension size based on their
model and density difference, customers can choose their preferred
package plans via contact Hainuo team in advance.
Answer2:For better meet customer’s special requirement of their
diversified application field, Customers can contact in details
with Hainuo team for a feasible customized package service.
Question 2, Can you tell a brief progress history of Hainuo Technology and
what specific achievement and merits rewarded in the HGBs field?
Answer1: The Hainuo Technology’s history can trace back to
2010s,officially founded in 2011s, the Hainuo technology was backed
the research by several renowed Governement owned institutions and
authority agencies and hence get tremendous technology breakthough
in a short time and now rank in the global list of most competitive
manufacturers.
Answer2: The Hainuo Technology has been rewarded for several significant
national prize and honor reward include the title “High-Tech
Enterprises”, “Outstanding Enterprise in Shanxi province”..,Whats
more the Hainuo Glass Bubble is applied in many significant China
national oil and ocean projects by CNPC and CNOOC those Monopolized
Enterprises.
Question 3,What protection steps should users take and be cautious when
remove HGBs exterior package?
Answer1: Before the unpackage,please place cartoon box or Ton bags in
spacious area with effective ventilation conditions,then gently and
slowly remove packaging bands of the cartoon and softly open the
inner small package bags.To better mitigate the dust emission ,lift
and down of bags should be controlled within slight vibration and
shake.
Answer2: Users simply need mind the dust emission during unpackaging ,both
lift and down of bags should be controlled within slight vibration
and shake.for user’s skin who have allergic symptom to dust and
other micro substance contact ,other safety protection kits is
suggested including safety eyeglass and gloves, please contact
local safety kits servicers for professional suggestions.
Question 4, What are advantages of using hollow glass bubbles ?
Answer: Hollow glass bubbles can be applied as a lightweight filler in
various industries,it has multiple advantages not only enhance
products’ Thermal Insulation, Fludity&Stiffness but also hugely
improve the original strength endurance and Chemical Resistance.
Question 5,What are some common applications of hollow glass bubbles?
Answer: Hollow Glass Bubbles covers wide application in
Aerospace,Rubber,Plastic,Marine and Construction industries.HGBs
are used as lightweight fillers which will improve products
performance and effectively reduce original production cost.
Question 6, What is the range of Hainuo HGBs density and size range?
Answer: It varies based on their physical application ,The typical density
range of Hainuo Glass Bubble is 0.11-0.606 g/cm³and the size range
from 10um to 115um .
Question 7,Are Hollow Glass Bubbles products environmental friendly?
Answer: Hollow Glass bubbles are environmental friendly product as its
made from natural sand so will not cause any side effect to both
users and environment ,they can be recyclable reused.The Hainuo
Technology Co.Ltd very stress this code and coherent it throughout
the whole production, this is also the idea and brand image that
Hainuo deliver to the public society .
Question 8,Can Hollow Glass Bubbles be used in 3D Printing?
Answer:Yes, hollow glass bubbles can be added to 3D printing materials,
such as polymers and resins, to reduce their weight and improve
their strength. They can also improve the printability of materials
and reduce warping.
Question 9,Can Hollow Glass Bubbles be used in Concrete?
Answer:Yes, hollow glass bubbles can be used as a lightweight aggregate in
concrete to reduce its weight and improve its thermal insulation
and fire resistance. They can also improve the workability and
durability of concrete.
Question 10,What is the annual total production volume of Hainuo HGBs ?
Answer:The Hainuo is currently able to meet altogether 15000 tonnes
requirement every year and this volume is hugely increasing with
the construction of its second line production project. By year
2026 ,the yearly production volume is expected grows to over 35000
tonnes.
Question 11,Is there anything attention or be noted when storing hollow Glass
Bubbles?
Answer: Yes,there are some imperative measures should be taken to ensure
stored glass bubbles in good condition. HGBs packages should be
placed and stored in dry area where not much damp and moist
affections,whats more,HGBs storage should avoid exposure to direct
sunshine,it is better they are stored in a cool and dark
place.Besides, its necessary to keep all packages tightly sealed in
case its emission as they are very micro particles.
