High Insulating Cenosphere Microballoons,Ceramic Microspheres
Cenosphere are lightweight, inert, hollow, nonmetallic spherical materials, composed largely of silica (SiO2) and alumna (Al2O3) compositions of Cenospheres are similar with glass and ceramic.Those hollow glass particles have also been called hollow ceramic spheres and micro spheres.
Benefits and Features of Using Cenospheres:
Hollow Sphere Low Bulk Densities Low-cost
High Compressive Strength Low Thermal Conductivity Good Sound Isolating
Good Insulation Stability in Chemicals Thermal Stability
Non Inflammable Resistant to Water Low Shrinkage
