Silicon Dioxide for Glass Microsphere/Glass Beads
Hollow glass microsphere is a hollow glass sphere with small size. It belongs to inorganic nonmetallic materials. The typical particle size range is 10-180 microns, and the bulk density is 0.1-0.25 g / cubic centimeter. It has the advantages of light quality, low heat conduction, sound insulation, high dispersion, electrical insulation and thermal stability. It is a new lightweight material with extensive use and excellent performance in 2008.
The color is pure white. It can be widely used in any products that are required for appearance and color.
And the content of SiO2 in glass microphere is more than 65%.It can make the glass beads harder,the hardness up to 6-7 moth, and enough elasticity, can be repeated several times, not easy to break, more than 3 times longer than the life of ordinary glass beads.
