High-performance glass bubble & hollow glass microsphere GS60 is a kind of ultra-lightweight inorganic non-metallic material with hollow structure, and it is a versatile and high-performance new lightweight material developed in recent years. It will be the new composite materials at twenty-first century. Its true density is 0.15-0.60g/cm3 with 2-120μm in diameter. It owns features with light weight, large bulky, low thermal conductivity, high compressive strength, smoothly mobility etc.
Why should we choose high-performance glass bubble & hollow glass microspheres?
Improving 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%.
More substitute ability for 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 by volume.
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 the density of products .
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.

To solve industrial problems
Application of hollow glass microspheres in paint
Hollow glass microspheres have the smallest surface area and low oil absorption rate, can significantly reduce the consumption of other components in paint.
The vitrified surface of glass microspheres can realize the chemical corrosion resistant, and reflexaction on light. Therefore, the paint can prevent from fouling, corrosion, UV, yellowing and scratching etc.
Thin gas inside the hollow glass microspheres with compact arrangement, makes low thermal conductivity, so that paint coating has a very good effect on heat insulation.
Hollow glass microspheres can effectively enhance the fluidity and smoothness of coating.
Hollow glass microspheres contain gas inside, so it has a good contractility resistance to hot and cold, thus enhancing the flexibility of coating, greatly reducing the cracking and peeling of the coating due to thermal expansion and contraction.
On premise of high filling level, the viscosity of paint will not be significantly increased, thus reducing the usage of solvents. It can reduce toxic gas emissions in the process of painting, and VOC indicator can be effectively reduced.
Dosage recommendation:The addition is normally about 10-20% of the total weight. Adding methods are proposed as follows: Last step. The hollow glass microspheres are proposed to add at the last step, and dispersed with low-speed, low shearing force mixing equipment. Due to its good liquidity,small friction, so it willeasily dispersed into mixture to completely keep wet within a short time. Through slightly extending mixing time can achieve uniform dispersion. Hollow glass microspheres are inert and non-toxic. Due to its light weight, attention should be specially paid when adding. We recommend adding the microspheres by step, that is, the addition quantity is 1 / 2 of the remaining beads each time. It can well avoid the microspheres floating into the air and make it disperse even more completely.
Application of hollow glass microspheres in the plastic
Hollow glass microspheres are used as filler of ultra-high molecular polyethylene. It is not only used as solid lubricant in process, but can modify the comprehensive mechanical properties of the ultra-high molecular polyethylene to improve its strength and abrasion resistance.
Nylon 6 with hollow glass microspheres has a higher tensile strength, impact strength, hardness and other improved mechanical properties and can prevent the material aging caused by the light and heat. With the increase of glass microspheres content, the Martin’s temperature of materials rises. It can used in the production of bearings, cameras, furniture and its accessories;
Hollow glass microspheres are added into rigid PVC to manufacture profiled materials, pipes and plates. These materials have good stability in dimension, then their the rigidity, heat resistance, productivity will be improved;
Filled into ABS，this can improve the size stability of material, reduce shrinkage, improve the compressive strength and flexural modulus, and improve the performance of the surface paint. So it can be widely used in production of TV cabinet, automotive plastic parts;
Filled into epoxy resin，it can reduce the material’s viscosity and improve the mechanical properties. So it can be used in production of composite foam plastic, deep-sea submarine, lifeboat, etc.
Filled into unsaturated polyester. It decreases the shrinkage and water absorption of materials, increase its wear resistance. Meanwhile, less space is produced when laminated and coated. So it can be applied in production of FRP products etc.
Application of hollow glass microspheres in the synthetic foam board
The composite material with hollow glass microspheres and resin is commonly referred as synthetic foam board, its main characteristics is low density. With high mechanical properties, it is a wide set of multifunctional composite materials for vibration damping, insulation, fire prevention. Now it is mainly used in manufacturing of aircraft, spacecraft, and ship etc. The synthetic foam with addition of hollow glass microspheres has not only the porous structure, but also makes core materials own low moisture absorption and high compressive strength due to its closed cell structure.
Application of hollow glass microspheres in the exploitation of oil and gas fields
Hollow glass microspheres itself is inert without pollution. As a continuous medium, low density drilling fluid with addition of hollow glass microspheres was incompressible, and all wells are uniform in density. Sludge cakes formed have good lubrication, reducing the risk of sticking. It is technically infeasible for drilling large deviated wells and horizontal wells since the recycled micro-foam and air drilling technology can not deliver MWD signal. However, hollow glass microspheres have an irreplaceable advantage for it can not affect the system signal.
Hollow glass microspheres have a good rolling performance, and it can increase the drilling rate, and significantly improve the drilling effectively.
Drilling fluid with hollow glass microspheres has feature of high temperature resistance, high pressure resistance, stability, durability, and can be recycled.
With the increase of pressure, low-density slurry cementing with hollow glass microspheres were adopted to consolidate the wells to prevent or reduce leakage, increase the cement top. It plays a significant role in increasing the exploration reserves, improving single well production, and effectively developing underground oil and gas resources so as to solve complex problems.
