function of Cenosphere powder :
Low Density: Density ranging from 0.50 g/cm3 to 0.80 g/cm3. Compared to most ground minerals and other resins,Cenospheres are 30-85% lighter.
Low resin demand/High loading potential: spheres have the lowest surface area to volume achievable with their spherical shape,cenospheres produce less viscosity.
High Compressive Strength: Cenospheres can greatly improve the weariness properties of the
end products.
Low Shrinkage: Cenospheres are one of the few products in the filler industry today that can meet the the requirements for low shrinkage.
Low Thermal,Electrical and sound Conductivity: Cenospheres are extremely resistant to heat and typically have a melting point in excess of 13000c. As cenospheres are hollow they have a relatively low co-efficient of thermal conductivity,typically 0.09w/mu
Inertness: Cenospheres can be utilized in solvents,organic chemicals water,acids and alkalies while maintaining their integrity.
Thermal stability: As cenospheres are formed in the boilers ,they are thermally stable in temperature exceeding 10000C
Insulation: Cenospheres can be used in electric filling and sealing materials ,instruments boards,
switches etc.
Cost effectiveness :Cenospheres are 50~200% less expensive than man made hollow glass speheres,in comparison to less expensive fillers.
