Product Specifications / Features
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.
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.

These glass beads are the substitute of sand or rice in Incense Burner.
The incense can be easily put in Incense Glass Beads. Also the beads are unbreakable and used permanently because they don’t absorb moisture like rice and sand.
The best benefit of Incense Glass Beads is that they are helpful for health because they emit the ultrared rays at a certain temperature degree.
The use of Incense Glass Beads can also be made for crystal vases with artificial flowers in a Buddhist Sanctum. Incense Glass Beads make Sanctum more elegant and dignified.

Weight reduction filler Hollow Glass Microspheres 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%.

Bioactive glass is a promising osteoconductive silica-based biomaterial for guidance of new bone growth. On the basis of several in vitro studies, the material appears able to promote osteoblast functions. In our in vivo study, the osteopromotive effect of bioactive glass microspheres seemed to surpass the osteoinductive action of direct adenovirus-mediated human bone morphogenetic protein 2 (BMP-2) gene transfer in a noncritical size bone defect model. The current study was initiated to elucidate the molecular mechanism behind bioactive glass action with or without adjunct BMP-2 gene transfer. A standardized bone defect of the rat tibia was filled with bioactive glass microspheres and injected with adenovirus carrying the human BMP-2 gene (RAdBMP-2). Control defects were left empty or filled with bioactive glass microspheres with injection of adenovirus carrying the lacZ reporter gene or saline. Quantitative polymerase chain reaction confirmed the expression of the transferred human BMP-2 gene at the defect area at 4 days, but not in intact reference tissues. Bone matrix components (collagens I, II, and III, osteocalcin, osteonectin, and osteopontin) and resorption markers (cathepsin K and MMP-9), determined by Northern analysis, showed a completely different pattern of gene expression in defects filled with bioactive glass compared with control defects left to heal without filling. Bioactive glass induced a long-lasting production of bone matrix with concurrent upregulation of osteoclastic markers, a sign of high bone turnover. Combining RAdBMP-2 gene transfer with bioactive glass decelerated the high turnover, but did not influence the balance of synthesis and resorption. This molecular analysis confirmed not only the highly osteopromotive effect of bioactive glass microspheres, but also the accelerated rate of new bone resorption on its surface. At least in noncritical size defects this impact of bioactive glass seems to saturate new bone formation on its surface and thereby overshadow the effect of BMP-2 gene transfer.
