Cenospheres
(Thin Wall Hollow Ceramic Microsphere)

SinoSi is dedicated to collecting, processing cenospheres for our customers world wide. As the by-product of power plant, cenosphere is widely used as filler material in various industries such as cement, rubber, plastics, resins, concrete, lightweight construction
prefabrications, etc.
Cenosphere is a glass hard, inert, hollow silicate sphere. Cenosphere is generally used to
reduce the weight of plastics, rubbers, resins, cement, etc.

Characteristics

Lightweight, Free-flowing, Gray or Off-white Color, Spherical, Inert, heat resistant and fire proof.

Consistency of properties

SINOSI has taken every possible measure to ensure consistency of physical and comical properties for specific customers. As we know majority of applications require relatively narrow range of fluctuation of properties such as density, color, size distribution, etc.

Applications

Refractory, PVC flooring, oil-well cements, brake linings, Phenolics, Epoxies, Cast Polyesters, synthetic marbles, syntactic foams. Low density cements, shotcrete and gypsum board joint compounds. Automotive sound-dampening sheets.

Advantages

Reduced weight, increased filler loadings, better flow characteristics, less shrinkage and warping. Improved physical properties in moldings, castings and laminates, reduced water absorption, improved flame retard, improved chemical resistance.

Zeeospheres
(Thick wall hollow ceramic microsphere)

Zeeosphere is a series of separated products directly from fly ash in dry conditions at the fly ash disposal area. With the advanced technology of bulk conveying, more and more power plants have adopted the method of fly ash dry disposal. This makes separation of cenosphere impossible. However, the dry fly ash presented us a chance to separate many other different glass particles with comparatively lower cost than wet material.
