Hollow glass microspheres ( also known as glass bubbles ) are hollow glass spheres made of chemically stable Soda-lime-borosilicate glass with thin walls(wall thickness 1~3.5μm). We have several grades available with true density ranging from 0.20g/cc~0.60g/cc, Sinosteel hollow glass microspheres can be used as lightweight functional additives for Composites,Thermal insulation paints/coatings, Sealant/adhesives, Low density cementing slurries and many more applications with very competitive quality and price.

Sinosteel Maanshan New Material Technology Co., Ltd., a wholly owned subsidiary of Sinosteel Maanshan Institute of Mining Research Co. Ltd., is a comprehensive high-tech company that specializes in research&development 、production and sales of high-performance Hollow Glass Microspheres.

Established in 1963, Sinosteel Maanshan Institute of Mining Research Co., Ltd (Hereafter, The Institute) used to be a key scientific research institute under the former Ministry of Metallurgical Industry. The Institute has been authorized to grant master’s degree (first-level discipline) by the Academic Degree Committee of the State Council since early times. The Institute, now as a national innovation-oriented company and a key high-tech company under the National Torch Program, is attached to Sinosteel Group Corporation Limited. The Institute has undertaken and completed a number of major national science and technology projects successfully, and won more than 680 awards of scientific and technological achievements at national or provincial levels by far.


Single From a cost perspective, if the hollow glass bubbles per unit mass of the same price, you should use the lowest possible density of hollow glass microspheres, so low unit cost.If just from a performance standpoint, because the larger the lower the density of the hollow glass microspheres diameter, large diameter also reduces the conductivity between the zinc coating, which reduces the resistance to salt spray paint, and therefore should be chosen particle size as small as hollow glass microspheres.There are on the one hand I must mention that, due to the formulation of other fillers such as zinc and iron phosphate high density, when the coating solution is stirred crashed hollow glass microspheres, and in the spray when a low intensity hollow glass microspheres are easily broken failure. Therefore, the density of the microspheres can not be selected too large, the particle size can not be too large, and the strength is sufficient.

Proposal to add the following methods:
In order to take full advantage of the characteristics of the hollow microspheres, recommended adding a last resort, that is added to the beads into the final as low speed mixing equipment dispersed using low shear force, because the spherical beads mobility well, between the friction is not large, so it is easy to disperse. You can complete a short wet, slightly extended mixing time to achieve uniform dispersion.
Beads chemically inert, non-toxic. However, because of a very light, so they need special attention added.Recommended stepwise addition method, which is the amount for each remaining 1/2 beads gradually added, this can be good to avoid beads float into the air and dispersed more complete.
