Description of hollow glass microspheres:


Hollow glass microspheres is pure white powders, which is hollow and transparent spheres under the microscope, and contains thin air inside. The main component is borosilicate. It is an inorganic non-metallic material.

Due to its hollow characteristics, compared with ordinary glass beads, it has the advantages of light weight, low thermal conductivity, sound insulation, high dispersion, good electrical insulation and thermal stability. It is a new lightweight material with a wide range of uses and excellent performance.

Widely used as an additive in Drilling fluid, Cementing slurry in petroleum exploration, Thermal Insulation Coating, Adhesives, Modified plastics in Lightweight transportation , Low dielectric engineering plastics, copper clad laminates for printed circuit boards in 5G communication, Rubber-plastic elastomer, Marine anticorrosion and solid buoyancy materials, etc.

Properties of hollow glass microspheres:



1. Good economy


Compared with fillers of other shapes, hollow glass beads have a small surface area to volume ratio and low oil absorption, which can reduce the amount of matrix resin and increase the amount of fillers. At the same time, glass beads with a smaller volume can be filled into larger gaps of glass beads, increasing the total filling amount, further reducing the amount of resin, and reducing the cost. Lightweight glass hollow microspheres can occupy more volume than ordinary fillers of the same weight. This means that hollow glass microspheres have more cost advantages when considering unit volume cost rather than unit weight cost.


2. Reduce viscosity and increase fluidity


The appearance of hollow glass microspheres is spherical. Compared with other irregular-shaped fillers, it is easier to flow and can roll like steel balls in a bearing. Therefore, adding hollow glass microspheres to the composite material can reduce the melt viscosity and The internal stress makes the processing and forming easier, which is conducive to the conventional forming of composite materials.


3. Reduce material density


Generally, fillers have a relatively high density and are added to plastics and rubbers as extenders. Although they can achieve the purpose of reducing costs, they tend to increase the density of the products and affect the performance and use of the products. Because hollow glass beads are hollow products, especially floating beads, the density is very small, about 0.40 ~ 0.75 g/cm3. Now some products, such as some hollow glass beads of 3M company, have a lower density, which can reach 0.125~0.16. g/cm3 level. Adding such low-density fillers to plastics can not only reduce costs, but also make products lighter.



Application of hollow glass microspheres


1. Low density drilling fluid and cementing Slurry

Hollow glass microspheres is widely used in deep oil wells to keep the constant stability of the density of drilling fluids; It can reduce friction during drilling process, extend the service life of drill pipes and drill bits, and greatly improve drilling effect as well as drilling performance;

2. Thermal insulation coatings and marine anti-corrosion coatings

The hollow glass microspheres can be directly added to the coating system in the form of filler. As a coating filler, it also has the following advantages: efficient filling, low oil absorption, low density, adding 5% (weight percentage) can increase the finished product by 25% to 35% (volume or coating area percentage), Thereby reducing the unit volume cost of the coating.

Hollow glass microspheres are closed hollow spheres, which are added into the coating to form many microscopic independent thermal insulation cavities. The chemically inert surface of the microspheres is resistant to chemical corrosion. When the film is formed, the particles of the glass microspheres are closely arranged to form a low porosity, so that the coating surface forms a protective film that has a blocking effect on moisture and corrosive ions, which plays a good role in protection

3. Modified plastics

Hollow glass microspheres for filling of ultra-high molecular weight polyethylene materials

The tensile strength, impact strength, hardness and other mechanical properties of nylon with hollow glass microspheres are improved, and it can prevent material aging caused by light and heat.

Filling rigid PVC with hollow glass microspheres to produce profiles, pipes and sheets can make the material have good dimensional stability, improve rigidity and heat-resistant temperature, and improve production efficiency; filling with ABS can improve the dimensional stability of the material , reduce shrinkage, increase compressive strength and flexural modulus, and improve surface paint performance.

Hollow glass beads are widely used in lightweight vehicles, such as car dashboards, car door trims, car door guards, car bumpers, passenger car seats, and engine covers.

4. Adhesive

The common adhesive filler, heavy calcium carbonate, has a density of 2.8g/ml, and the density of hollow glass beads is very low. Only a small amount of mass (1%-2% by mass) can be added to reduce the cost. Hollow glass microspheres are used as adhesive additives, which can improve the chemical resistance of adhesives, reduce shrinkage and warpage, reduce resin consumption, and reduce VOC.

5. Emulsion Explosives

The introduction of hollow glass microspheres in the emulsion explosive overcomes the above shortcomings, greatly improves the detonation performance of the explosive and significantly improves the storage stability. Its main feature is the use of the sensitization effect of hollow glass microspheres. It can significantly improve the detonation performance of emulsion explosives and prolong the storage period.

6. Marine solid buoyancy materials

The density of hollow glass microspheres can be adjusted to better. adjust the specific gravity of buoyant materials, the volume filling rate is higher, and the water absorption rate is reduced. Commonly used marine solid buoyancy materials, such as offshore platforms, offshore oil pipeline systems: oil transportation, exploration pipelines, deep sea carrying equipment, underwater engineering testing instruments, etc.
