WHY CENOSPHERES?Cenospheres are utilized as a High Performance Filler Material. Cenospheres can replace other fillers such as: Glass Spheres, Calcium Carbonate, Clays, Talc, and various Silicas. Cenospheres can also be utilized as an extender in many resin applications.
FILLER or "HIGH PERFORMANCE FILLER"
Why are cenospheres a High Performance Filler?
- LOW DENSITY: When density counts, cenospheres can be the answer with a density ranging from 0.50 to 0.80. Compared to most ground minerals and other resins, cenospheres are 30% - 85% lighter,
- IMPROVED FLOWABILITY: With the spherical shape of cenospheres, the flow rate will improve greatly for most applications.
- LOW RESIN DEMAND / HIGH LOADING POTENTIAL: Spheres have the lowest surface area to volume ratio achievable. With their spherical shape, cenospheres produce far less viscosity.
- LOW SHRINKAGE: Cenospheres are one of the few products in the filler industry today that can meet the requirements for low shrinkage. When used in high volume loadings, cenospheres can reduce shrinkage.
- STRENGTH: Cenospheres are three to ten times stronger than most man-made hollow glass spheres. Unlike glass spheres, cenospheres can produce a higher compressive strength due to a stronger outer shell.
- INERTNESS: Cenospheres can be utilized in solvents, organic chemicals, water, acids, or alkalis while maintaining their integrity.
- THERMAL STABILITY: Because cenospheres are formed in the boilers, they are thermally stable in temperatures exceeding 1,800 degrees F.
- COST EFFECTIVE: Cenospheres are 50% - 200% less expensive than man-made hollow glass spheres. Compared to less expensive fillers, cenospheres are cost effective based on volume loading and weight reduction.

CONDUCTOSPHERES™ are hollow glass microspheres coated with silver. The silver coating makes the microspheres highly electrically conductive resulting in a filler that is considerably lighter than solid silver particles and which can be used in numerous applications.
CONDUCTOSPHERES can be incorporated into paints, adhesives and composites to provide these materials with electrical conductivity and to shield against electromagnetic interference (EMI).
The CONDUCTOSPHERES range includes products based on borosilicate glass microspheres, aluminosilicate cenospheres and expanded volcanic ash particles. The size, density and silver loading of CONDUCTOSPHERES can also be tailored to meet the customer's specifications.
Please contact us to discuss your requirements.
