Cenosphere is a kind of borosilicate raw material with the granularity of 1- 250microns. It is of light weight, low heat conduction, high strength, and good chemical stability. Its surface, after special process, is lipophilic and water resistant, so extremely easy to disperse in the organic materials.
This product is already used in man- made agate, marble and fiberglass reinforced plastic bowling. It obviously reduces product weight with good heat preservation and insulation effects.
Remarkably enhancing emulsified blasting explosive performance, cenosphere lengthens preserving time for civil emulsified blasting explosives. Furthermore, it can be used in the atomic ash to increase volume to improve polishing performance, and to enhance acid proof and antalkali performances.
In cementing, cenosphere 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
Cenosphere is a HIGH PERFORMANCE Light weight product, it has below characters:
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.
