Cenosphere/Hollow Ceramic Microspheres
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
