Glass Microsphere

Product Name: CenospherePlace of Origin: ChinaCenosphere is a kind of borosilicate raw material with the granularity of 1-250 microns. It is of light weight, low heat conduction, high strength, and good chemical stability. Its surface, after special process, is lipophilic and water hatred to extremely easy to disperse in the organic materials. This product is already used in manmade agate, marble and fiberglass reinforced plastic bowling. It obviously reduces product weight with good heat preservation and insulation effects. Remarkably enhancing emulsified blasting explosive performance, cenosphere lengthens preserving time for civil emulsified blasting explosives. Furthermore, it can be used in the atomic ash to increase volume to improve polishing performance, and to enhance acidproof and antalkali performances.
