Cenosphere(Hollow Ceramic Microspheres) are lightweight, inert, hollow, nonmetallic spherical materials,composed largely of silica (SiO2) and alumna (Al2O3) compositions,similar with glass and ceramic.

Compared to irregular-shaped and partially-spherical fillers, the 100% spherical shape of Ceramic Microspheres,

provides improved processing and performance. Being inert it is not affected by solvents, water, acids or alkalis. 

75% lighter than other minerals currently used as a filler or extender.

Color: range from gray to light gray.

Features:

• Spherical Shape                          • Ultra Low Density                • Heat Resistance

• Improved Flowability                    • High Insulating                    • Low-Cost

• High Strength                               • Chemical Inertness             • Good Sound Isolating

• Low Thermal Conductivity           • Low Shrinkage                     • Reduced Resin Demand
