Hollow glass ball  : Hollow glass beads are a loose, free-flowing white powder. Hollow glass beads were first produced in the 1950s and are a by-product of the development of solid glass beads.

Its main ingredients are borosilicate glass and soda-lime glass, which is a high-strength polymer filler. When observed under a microscope, hollow glass beads are hollow sealed spheres with a diameter usually between 10-250 microns. The larger the diameter of the hollow glass beads, the higher the hollowness.

Hollow glass beads have high chemical stability, good electrical insulation, low oil absorption, low density and high strength.

Among them, low density is the most significant characteristic of hollow glass microspheres.

This characteristic allows hollow glass microspheres to replace a large number of high-density materials with lower quality and price.

For example, using the same volume of solid filling material and hollow glass beads, the weight of the hollow glass beads per unit volume can be half or even a quarter of the solid filling material.

There are also differences in the quality and price of different types and grades of hollow glass beads, which mainly depend on the raw materials, density, strength, particle size and distribution, functionality, cleanliness and volume of the hollow glass beads.

Hollow glass beads have been widely used in many fields such as lightweight concrete, engineering plastics, and synthetic wood, and can exhibit superior properties to other materials in different fields.
Hollow glass beads can be used to make fiberglass, which can reduce the weight of the product and make it easier to process and manufacture, and enhance the rigidity, impact strength and bending strength of the product.

FRP made of hollow glass beads has higher chemical stability, more stable product dimensions, good reprocessing performance, and is easy to cut, drill, nail, etc. More importantly, hollow glass beads can replace expensive resin and reduce the cost of FRP production.

These lightweight products are widely used in various industrial fields, such as vehicles, ships, sandwich composite panels for construction, sports equipment, models, etc.

Hollow glass beads can be used to make various lightweight putties such as primers, architectural coatings, adhesive cement, mortar, etc. It has the characteristics of low fluidity, wear resistance, opacity, and high pressure resistance.

The putty made of hollow glass beads has the advantages of light weight, strong adhesion, easy application, low shrinkage, and good stability. It can shorten the curing time of putty and significantly improve the processing performance of products such as sanding and polishing.

It can be widely used in various vehicles, especially high-end cars and ships.
Hollow glass beads can also be used to make synthetic wood. Synthetic wood made of hollow glass beads can have the same texture and structural properties as wood.

While saving costs, it can also play the role of heat insulation, reduce specific gravity, and reduce thermal expansion. The manufactured products can be used in repair operations such as high-end sanitary ware, furniture castings, decorative panels, lightweight floors, ships, and machine tools.
With the continuous advancement and development of science and technology, hollow glass beads are also constantly developing, innovating and evolving, with higher sphericity, tighter tolerances and narrower particle size distribution.

In addition to traditional industrial manufacturing fields, hollow glass beads can also be used in new material fields such as military, biotechnology, medical equipment, and high-tech equipment.

For example, hollow glass beads have smaller particle sizes and strong compressive strength, which can reduce the dielectric constant of 5G materials, increase wave transmittance, and meet the strict requirements for product particle size and compressive strength in the field of high-tech equipment.
Hollow glass beads can also be used to make emulsion explosives. Hollow glass beads are excellent sensitizers for emulsion explosives.

The emulsion explosives produced using hollow glass beads have high sensitivity and strong explosive power, and even after long-term storage, their performance is far superior to that of expanded perlite, chemical Explosives produced using foaming and other sensitizers provide a strong guarantee for improving the level of emulsion explosives in China and entering the international market.
