Lightweight Cenosphere Powder Ceramic Hollow Microspheres
Lightweight Cenosphere Powder Ceramic Hollow Microspheres
Name: Cenosphere,Hollow Ceramic Microspheres,Aluminosilicate Microspheres
Material: fly ashes formed at coal-fired thermoelectric power stations.
Particle Shape: Hollow Sphere
Particle Size:75-850microns(most often 100-500microns).
Colors range from gray to light gray.
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. They are 75% lighter than other minerals currently used as a filler or extender.
Advantages of Using Cenosphere:
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
