Hollow glass microspheres are a ultra-lightweight, inorganic, non-metallic, hollow alternative to conventional fillers and additives. They find applications in many demanding industries such as paints, coatings, adhesives, sealants, cast polyester, compounding and many more. The low-density material is used to reduce weight, lower costs and enhance product properties.

The unique spherical shape of the hollow glass microspheres offer a number of important benefits, including higher filler loading, lower viscosity and reduced shrinkage. It further makes it more adaptable to a variety of production processes including spraying, casting and molding.

The chemically stable soda-lime-borosilicate glass composition provides excellent water resistance to create more stable emulsions. They are non-combustible and non-porous, so they do not absorb resin. The hollow glass microspheres also create stable voids, which result in low thermal conductivity and low dielectric constant.

Hollow glass microspheres are available in a variety of sizes and grades to help you meet your product and processing requirements.

The physical characteristics of HG hollow glass microspheres lead to the following advantages:

1. The alkali lime borosilicate component of the glass microsphere makes its chemical property stable and inert, so that it can be safely used as a filler or additive without worrying about its reaction with the substrate or other substances, and can withstand other chemical corrosion except strong alkali.

2. The perfect sphericity endows it with excellent isotropic consistency, so that it will not warp and shrink due to stress inconsistency after processing.

3. The hollow glass microsphere is a small round ball. In the liquid, it acts like a miniature ball bearing, and has better fluidity than the fillings of sheet, needle or irregular shape. The resulting microsphere effect reduces the viscosity of the mixture, and the filling performance is naturally excellent; Good processing performance can improve the production efficiency by 10%~20%.

4. The perfect sphericity makes it have a small specific surface area of Z, so its oil absorption is low. Compared with the conventional filler calcium carbonate, the oil absorption rate/amount of hollow glass microspheres is much lower. The oil absorption rate of different models of products per 100g is between 7 and 40mg, while the oil absorption rate of light calcium carbonate per 100g is as high as 120 to 130mg, and that of heavy calcium carbonate is as high as 50 to 60mg. The amount of resin is reduced. At the same time, because it can increase the fluidity of resin, the resin is processed only as a base material rather than a filler, thus reducing the amount of resin.

5. Due to the particle size distribution of glass microspheres, small microspheres fill the pores of large microspheres, thus increasing their solid content. At the same time, their volatilization is very low, which reduces VOC

6. The color is white, so it has good color compatibility.

7. Its low true density and strong compressive strength result in its high compressive strength density ratio, which makes it not only play the role of filler or additive with reduced density, but also have a good survival rate and stability in the processing process in some applications requiring high compressive strength, such as extrusion, die or petroleum industry

8. The particle size is small, which will not reduce its toughness when mixed with resin for processing.

9: The interior of the hollow glass microsphere is a vacuum thin gas. Two different materials have different densities and thermal conductivity, so it has the characteristics of sound insulation, heat insulation and low thermal conductivity. It is an excellent filler for various heat insulation and sound insulation products. The thermal insulation properties of the microspheres can also be used to protect the products from thermal shock caused by alternate changes between hot and cold conditions

10: The closed space ratio is very high. At the same time, the sphere is tight and perfect, and it is insoluble in water, which makes its application in water very stable. Water will not enter the interior of the sphere, so it does not cause the problem of density increase. At the same time, because it is insoluble in water, its application in water, such as yachts, rowing, etc., is also extremely stable.

11: Some tests have shown that hollow or low hardness fillers will absorb and digest the impact strength when impacted, so as to improve the impact resistance of materials. Therefore, as a filler, it can improve the physical and mechanical properties of plastic products. At the same time, the hardness and elastic modulus of the material can be greatly increased, and the stiffness and stress damping capacity can also be improved.

12: It can maintain its stability below 600 ℃, so it is stable in some applications requiring slightly higher temperature.

Syntactic foam is a solid insulation material, featuring a foam-like structure. It’s a composition of hollow glass microspheres and a polymeric matrix material. In this study it consists of hollow glass microspheres and an epoxy resin matrix.

The present paper deals with the influence of modified inner interfaces (achieved by silane-coated hollow glass microspheres in order to improve the adhesion quality between the hollow glass microspheres and the epoxy resin matrix) on the electrical properties of the material. The experiments show that the silane-coating (also known as silanization) has a positive influence on the breakdown field strength under electrical ac and dc short term stress. The experiments are conducted for different degrees of filling of the hollow glass microspheres (10 vol.% … 50 vol.%).

It is shown, that the influence of the silanization becomes more significant with higher degree of filling. The life time of the material under electrical ac as well as dc stress can also be improved by a silanization. The dielectric properties (loss factor and relative permittivity) are not influenced by a silanization. Measurements of the viscosity of syntactic foam verify that a silanization reduces the viscosity of the uncured, liquid material during the manufacturing process. Hereby, an improvement of the material’s production quality can be achieved at high hollow glass microspheres’ filling degrees.

1. The alkaline lime borosilicate ingredients of the glass microspheres make it stable and inertia for its chemical properties, which gives them safely as a filler or as an additive, without worrying Can resist other chemical corrosion other than strong alkali.
2. The perfect spherical shape gives them excellent consistency, so that after processing, it will not cause warning and contraction due to inconsistent stress.
3. The hollow glass micro -ball is a tiny ball. In the liquid, the action -like micro -rolling bearing bearing should be more liquid than the fillers of the chip, needle, or irregular shape. Decreasing the viscosity of the mixture, the performance of the model is naturally excellent; good processing performance can increase production efficiency by 10%to 20%.
4. The perfect spherical shape makes it have a small ratio of Z, so its oil absorption is low. Compared with the conventional filling material calcium carbonate, the fuel absorption rate/volume of hollow glass microspheres is much lower, and different types of products are 100 grams per 100 grams The oil absorption rate is between 7 and 40 mg, while the oil absorption rate per 100 grams of light calcium carbonate is as high as 120 to 130 mg, and the heavy calcium carbonate is as high as 50 to 60 mg. The amount of resin is reduced, and at the same time, because it can play a role in increased liquidity of the resin, the resin can only be processed as a substrate rather than the filler, which also reduces the amount of resin.
5. Due to the particle size distribution of glass microspheres, small microspheres fill the gap of large microspheres, which increases its solid content. At the same time, its volatile capacity is very low, which reduces VOC.
6. The color is white, so it has good color compatibility.
7, very low real density and strong compressive strength, resulting in its high compressive strength density ratio, which makes it in some applications that require high pressure resistance, such as squeezing, pressing, or pressurizing, or pressing, or pressing, or pressing, or pressing, or pressing, or pressing, or pressing, or pushing, or pushing, or The oil industry can not only play the role of fillers or additives that density density, but also enable it to have a good survival rate and stability in the processing process
8. The particle size is small, and it may not reduce its toughness when mixing with the resin.
9: The interior of the hollow glass microsphere is a vacuum and thin gas. There are poor density and heat conduction coefficients in two different materials. Therefore, it has the characteristics of sound insulation, heat insulation, and low heat conduction. Fill. The thermal insulation characteristics of microspheres can also be used to protect the heat shock caused by alternating changes between the products and the cold conditions of the product.

10: The closed rate is very high, the spherical shape is tight and perfect, and it is insoluble in water, so that its application in the water is also very stable, and the water will not enter the inside of the microsphere. Therefore It is insoluble in water, and its applications in water such as yachts and rowing are also extremely stable.
11: As a test shows that the fillers of hollow or low hardness will absorb and digest the impact intensity when they are impacted, which improves the impact performance of the material. Therefore, it can improve the physical and mechanical properties of plastic products. At the same time, its filling plastic can greatly increase the hardness and elastic modulus of the material, and the ability of stiffness and stress damping has also improved.
12: It can maintain its stability below 600 degrees, so it is also stable in some applications that require a slightly higher temperature.

Strain hardening cementitious composites (SHCCs) with superior tensile strength and ductility have been utilized as an effective repair material. A corrosion-resistant binder, calcium aluminate cement (CAC)–ground granulated blast-furnace slag (GGBFS) blends, has been introduced into SHCC to expand its application in the concrete sewage network rehabilitation.

As a repair material, the lightweight property is particularly favorable as it can broaden its functionality. This article presents a study on developing a novel lightweight CAC-GGBFS-blended SHCC using hollow glass microsphere, namely, HGMLW-SHCCs. The fine silica sand content was substituted with hollow glass microsphere at 25, 50, 75, and 100 vol% in HGMLW-SHCC.

We examined flowability, density, uniaxial compressive behavior, direct tensile behavior, and pseudo strain-hardening indices. Microstructure analysis was also conducted to understand the meso-scale behavior of this new lightweight composite. The newly developed HGMLW-SHCC had a 28-day density of only 1756 kg/m3. Compressive and tensile strengths were determined in the range of 62.80–49.39 MPa and 5.81–4.19 MPa, respectively. All mixtures exhibited significant strain-hardening behavior.

Even though the increased hollow glass microsphere content negatively affected the tensile strength of HGMLW-SHCC, it had a positive effect on its ductility.

In addition, hollow glass microsphere can reduce crack width and tensile stress fluctuations significantly. The results showed that hollow glass microsphere was a promising material for producing strong and lightweight corrosion-resistant SHCCs to be used as a retrofitting material in the wastewater industry.

The high-performance hollow glass microspheres, a kind of ultra-light inorganic non-metallic powder with hollow “ball-bearing” shapes, have been developed into a new type of high performance lightweight material and have been widely applied in recent years. It will be the main direction for new-type compound materials in the 21st century. Its true density is 0.20-0.60 g/cm3; particle size is 2-130μm; Due to its excellent advantages of light weight, bulk density, lower thermal conductivity, higher compressive strength, improved dispersion and liquidity, and excellent chemical stability, it can be used as filler in painting, rubber, plastics,frp, artificial marble, putty, exploitation of oil and gas and other materials.

The high-performance hollow glass microspheres are alternatives to conventional fillers and additives such as silicas, calcium carbonate, talc, clay, etc., for many demanding applications. These low-density particles are used in a wide range of industries to reduce part weight, lower costs and enhance product properties.

The unique spherical shape of hollow glass microspheres offers a number of important benefits, including: higher filler loading, lower viscosity/improved flow and reduced shrinkage and warpage. It also helps the hollow glass microspheres blend readily into compounds and makes them adaptable to a variety of production processes including spraying, casting and molding.

The chemically stable soda-lime-borosilicate glass composition of hollow glass microspheres provides excellent water resistance to create more stable emulsions. They are also non-combustible and nonporous, so they do not absorb resin. And, their low alkalinity gives hollow glass microspheres compatibility with most resins, stable viscosity and long shelf life.

This paper will focus on recent experiments having 2 primary objectives: demonstrating appropriate formulating with hollow glass microspheres and developing experimental data that directly compared standard SMC to low-density, hollow glass microsphere filled SMC.

The purpose of this paper is to investigate 2 issues involving the use of hollow glass microspheres in sheet molded compound (SMC): 1) demonstrate the value of using volume fraction over weight fraction formulating to evaluate materials with significantly different densities and 2) directly compare physical property data of low density SMC to standard density commercially available SMC. The primary benefit of using hollow glass microspheres in SMC, for the automotive industry, is reducing the weight of SMC parts.

Hollow glass microspheres have been used commercially as a filler to produce low-density SMC parts for many years. These parts are primarily used in specialty applications on low volume vehicle platforms. In the past, experiments have been conducted using hollow glass microspheres as a low-density filler in SMC with mixed results.

The strategy of combining the traditional reinforcement of glass fibers (GF) with lighter hollow glass microspheres can afford to fulfill the need for potential light-weight and high-strength modern materials required in various sectors, such as automotive and aerospace industry applications.

This work fabricated composites of PA6/GF/HGM by melting blending in a co-rotating twin-screw extruder, and subsequently, injection molded. The effects of hollow glass microsphere content on the density, morphological and mechanical properties were investigated and the PA6/GF/HGM composites properties were compared to the properties of the traditional PA6/GF (70/30) wt% composite, widely used today in automotive industries.

With the increase of hollow glass microsphere amount in the formulations, a reduction of between 3 and 12% in density was achieved with a slight reduction in its mechanical properties, showing that this new strategy can be applied to replace the PA6/GF (70/30) wt% composite, providing a considerable weight reduction for these materials.

Glass microspheres have a very important role in production and life. The glass micro -balls are not only light quality, low heat conduction, high strength, and good chemical stability, but also have the performance of hydrocariasis on the surface, which is easy to scattered in the organic material system. So what are the main characteristics of glass microspheres?
Main features of glass microspheres
1. There is a scattering effect on visible spectral range light. The glass material is actually colorless and transparent, but because the glass ball has a scattering effect on the full visible spectral range of the spectral range, it looks white. However, when it is added to the color material, it is also scattered with the light of the material color, so it can be widely used in any material required by the appearance and color without affecting the color of the original material.
2. Lear density. The density of glass microspheres is about one -third of the density of traditional filling particles. After filling, it can greatly reduce the base weight of the product, and the large volume makes it replace a large amount of other raw materials and reduce the cost of the product.
3. It has parental oil. Weting and decentralizing hollow glass microspheres can be filled in most thermal thermoplastic resins, such as polyester, epoxy resin, polyurethane, etc.
4. High decentralization and good liquidity. Because the glass micro -ball is a tiny ball, it is more liquid than the fillers of the liquid resin than the chip, needle, or irregular shape, so the model is excellent. What’s more important is that this small micro -ball is different, so it will not produce disadvantages of inconsistent contraction rates caused by different parts of the orientation, ensuring the size of the product stable and not warpage.
5. Low water absorption. The interior of the glass microsphere is thin gas, so it has the characteristics of sound insulation and heat insulation. It is an excellent fillers for various insulation and sound insulation products. The heat insulation characteristics of glass microspheres can also be used to protect the heat shock caused by alternate changes between the products and the conditions of rapid heat and cold. The high ratio resistance, the extremely low water absorption rate allows it to be widely used in processing and production cable insulation materials.
6. Low oil absorption. The particles of the sphere determine that it has the smallest surface area and low oil absorption rate. During the use process, the amount of resin can be greatly reduced. Even if the amount of high addition is added, the viscosity will not increase much, which greatly improves the production operation conditions. Increase production efficiency by 10%to 20%.
