Hollow glass microspheres, made of Soda Lime Borosilicate Glass, are hollow spheres which grain size is 10-250microns, wall-thickness 1-2 microns, filled with inert air or gas. They are produced at the high temperature of 700-800 degrees Celsius through complicated chemical and physical transformation. Hollow glass microspheres are white and the specific gravity of them is about 0.25-0.60g/cc. They have much merit, such as lightweight, great buoyancy, hard, rigid, waterproof, innoxious, insulative, low heat conductivity, higher mechanical strength and excellent chemical stability,etc. Their surface was treated by the special way and the products are dispersed very easily in organic materials such as resin.
Hollow glass microspheres are widely used in composite materials such as FRP, man made marble and man made agate. They can decrease the weight of the composite materials and the composite materials have excellent performance of sound insulation and heat preservation, and they can improve the mechanical performance of the composite materials such as strengthened rigidity, enhanced anti-impact property, excellent anti-breaking property and re-processing function. Hollow glass microspheres are applied in a wide range of fields such as aviation, space flight, new bullet train, luxurious yacht, adiabatic dope, bowing balls, in which they play a distinctive role. Hollow glass microspheres are the excellent sensitized of emulsion explosive. They can improve the detonation property of emulsion explosive and prolong the shelf period of emulsion explosive. When used in the resin putty, hollow glass microspheres can increase the volume of resin putty, improve its polishing function. Packing: net 10kgs in Plastic film lined plastic weaving bags or strong cartons.

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 0.15-0.60 g/cm3; particle size is 5-180μm; 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, glass steel, man-made stone, putty, exploitation of oil and gas and other materials.
Glass beads for sandblasting has the features of chemical stability, high mechanical intensity and hardness. They can be blasted onto the object surface with compressed air and can be used on compress glass, rubber, plastic, moulds with metal casting or compressing. The jetting balls would help reduce elasticity of the surface materials and increase wearing capacity.

Someone is moving its glass microspheres into greenhouse films for the agricultural market.
Using microspheres can allow producers to make more amounts of low density and linear low density film with the same amount of resin, application development engineer Fernando Cervantes said at Plastimagen 2016 in Mexico City.
Microspheres also can provide whiteness to films, allowing for the replacement of titanium dioxide, he added. The materials also can spread light over a greater area, which helps plant growth.
Development of microsphere films began last year in the U.S. St, Paul, Minn.-based they now is working with film producers on the new application.
In Mexico, they have operated an innovation center in San Luis Potosi since 2013. Overall, they have done business in Mexico since 1947 and employs a total of 7,000 there.
They microspheres were used in body panels that were honored in November by the Society of Plastics Engineers’ automotive division. The award went to General Motors Co. for body panels made using composite material from Continental Structural Plastics. Auburn Hills, Mich.-based CSP replaced calcium carbonate with hollow glass microspheres and a proprietary surface treatment to achieve mass reduction of at least 28 percent vs. standard materials.
In 2015, they posted sales of just over $30 billion. Its products include adhesives, abrasives and specialty materials.

We can not only produce common glass beads, but also developed coating technology. The coated glass bead is a new product of glass beads developed in recent years,which is used for road graticule surface spreading. With the excellent charcteristics,the great majority of users have paid more attention to it .
The coated glass bead have been treated with high quality organic materials on their surface, thus bearing better features in quality. Our company has developed this unique product after absorbing advanced technology from foreign countries and it has the following advantageous features:
Glass beads surface coating is not easy to be eroded. In the process of storage and usage, glass beads whose surface is easy to be moisture is in humid atmosphere, It leads to light scattering,and therefore influences the direct reflection.
Glass beads coated material is a kind of organic material which may have better consolute with road coating material. While being spread on the road graticule surface,it is not easy to come off, It has stronger adhesion force specially used on coating material graticule of constant temperature (including water soluble coating material)and may maintain light reflection effects for a long time.
Coated glass beads has better adhesiveness with road coating material,particle sedimentation can be controlled after surfacer spreading through reasonable galss beads particle grading so as to ensure better reflection effect of the graticule.
Coated glass beads has good fluidity,with the characteristic of non-blocking. mean spreading,easy construction and good reflection effect.It is proved practically that it can save about 15%usage amount.

Improve flow properties
Hollow glass microsphere is a tiny sphere with high ball-type rate. Its ball-bearing effect can improve its mobility and reduce the viscosity and internal stress of resin mixture. Therefore, during processing, less heat is produced in composite materials so as to prevent inadequate lubrication and partial thermal decomposition. It is more likely to extrude when molding, which can not only reduce defects in products, but also improve the production efficiency by 15% -20%.
A superior substitute of resin
Hollow glass microspheres occupy less surface area, low oil-absorption rate, and evenly disperse in mixture. Its easy compression and integration permit high filler loadings. It significantly reduces the consumption of resins, increases the amount of filler, and effectively reduces VOC indicators, and costs as well.
Low shrinkage and warpage
Hollow glass microspheres have the feature of isotropism and high-filling, hence the dimensional stability of the product will be very high and it will reduce the shrinkage and warpage. With an appropriate filling ratio, the toughness of the products, impact-resistance and surface hardness can be significantly improved.
More economical
The density of high performance hollow glass microspheres is only a fraction of that of the resin. A small amount of hollow glass microspheres will be able to replace heavier materials. When considering the cost per unit volume, rather than cost per unit weight, high-performance hollow glass microspheres can significantly reduce costs.
Adjusting product density
The density of hollow glass microspheres is usually 0.20 ~ 0.60g/cm3, and the density of mineral filler is generally around 2.7 ~ 4.4 g/cm3 (The data adopted is the true particle density). In order to obtain the equal size, 14 kilograms or more of talc must be used to obtain the same effect of 1 kg of hollow glass microsphere. Hence the desired ideal density can be obtained by adding appropriate proportions of hollow glass microspheres.
