Glass Bubbles
Our meticulously produced Glass Bubbles typically have diameters of 10-250 microns, wall thicknesses of only 1-2 microns, and densities of 0.1 kg/liter to 0.7 kg/liter. This gives them a number of excellent properties:
Tiny size: Hollow glass beads have diameters down to the micron level, allowing them to be easily mixed with other materials to form excellent composites.
Low density: Due to their hollow structure, hollow glass beads tend to be lighter than materials of the same volume, making them ideal for lightweight product design.
Abrasion and compression resistance: Despite their tiny size and hollow shape, hollow glass beads have excellent compression resistance to meet grinding and polishing requirements, resulting in products with high stability and durability.
High Reflectivity: Glass Bubbles reflect external light and produce a fluorescent effect, making them suitable for use at night or in low visibility environments. Also, its ability to reflect visible and infrared light from the sun makes it an excellent thermal insulator and fluorescent agent.
Fireproof and corrosion-resistant: It has excellent fireproof performance, insoluble in most acid and alkali solutions, easy to store, moisture-proof and self-cleaning, and has excellent corrosion resistance.
Strong mobility: the spherical structure of hollow glass beads makes it easy to roll in various fillers, with excellent mobility, easy to be evenly coated and sprayed, and not easy to be agglomerated. At the same time, it also has strong adhesion, not easy to fall off, to ensure a long service life.
Glass Bubbles is these excellent physical and chemical properties that make hollow glass beads have a wide range of application prospects in both traditional industry and new material fields.

Urban road traffic marking: you can spray hollow glass beads on the surface of traffic marking, or mix it with paint and apply it to make all kinds of traffic marking.
Its high reflectivity can ensure the reflective performance at night, while its heat-resistant, wear-resistant and pressure-resistant properties make the markings stay clear for a long time and reduce the maintenance cost.
Filler and reinforcing agent: Hollow glass beads can be used as high-quality filler and reinforcing agent in the fields of medical devices, automobiles, aircraft, engineering plastics and so on.
It not only reduces the weight of the product, but also reduces the amount of resin, lowering the production cost and transportation cost. At the same time, it can also give the product more stable chemical properties and extend the service life of the product.
Mechanical sand blasting and shot blasting: The high hardness and finish of hollow glass beads make it an ideal material for industrial sand blasting and shot blasting.
It can easily treat the surface of stainless steel products, clean molds, remove edge splinters, etc., and at the same time, give the product a unique polishing effect, strengthen the finishing process and cleaning and polishing effect.
Next, let’s learn more about the appeal of hollow glass beads. This hollow glass microspheres with soda-lime borosilicate glass as the main ingredient appear as micron-sized hollow transparent glass spheres under the microscope.
Its smooth surface and white powdery appearance are impressive. But more importantly, with its low density, good fluidity and chemical stability, it has demonstrated its unique advantages in traditional industrial fields such as adhesives and rubber, as well as in new fields such as aerospace and 5G communications.
Light mass and bulk specific gravity, low density: Compared to other traditional industrial filler materials, hollow glass beads have a lower density, usually between 0.2 g/cm³ and 0.7 g/cm³.
This makes it an excellent bulk filler, reducing production costs and product weight. At the same time, its low oil absorption and low viscosity make it a good alternative to resin fillers.
Easy to flow: The miniature regular spherical structure of hollow glass beads makes it easier for the particles to roll with each other, with excellent dispersibility and flowability.
In the actual production process, this fluidity can play lubricating role to improve the production efficiency of the product.
In summary, hollow glass beads, with its excellent performance and wide application prospects, has undoubtedly become a bright pearl in the field of modern industry and new materials.
