Cenosphere:

cenosphere is one of the best filling materials for paint, printing ink, carbon, fiber, GRP, leatheroid, rubber, plastic, petroleum field(anchoring, pipeline, anticorrosion and warm keeping),and so on.

 Cenospheres are light are light gray or off-white, light, inert and nonmetallic hollow ceramic spheres in the range from *0um to **0um.With N2 or CO2 inside and over *5% spheres, the material has excellent fluidity as well as sound electric and heat insulation.

Chemical Composition

Physical Properties of Cenosphere

Characteristics of Cenosphere

1. IMPROVED RHEOLOGY: Cenospheres are nonmetallic hollow ceramic spheres in the range from *0um to **0um. With the spherical shape of cenospheres, rheology will improve greatly for most applications.

2. LOW DENSITY: When density, counts, cenospheres can be the answer with a density ranging from 0.*0g/cm3 to 0.*0g/cm3. Compared to most ground minerals and other resins, cenospheres are ****5% lighter.

3. LOW RESIN DEMAND/HIGH LOADING POTENTIAL: Spheres have the lowest surface area to volume achievable. With their spherical shape, cenospheres produce far less viscosity.

4. HIGH COMPRESSIVE STRENGTH: cenospheres can greatly improve the weariness properties of the end products.

5. LOW SHRINKAGE: cenospheres are one of the few products in the filler industry today that can meet the requirements for low shrinkage.

6.LOWTHERMAL,ELECTRICAL,AND SOUNDCONDUCTIVITY: cenospheres are extremely resistant to heat and typically have a melting point in excess of ***0C. As cenospheres are hollow they have a relatively low coefficient of thermal conductivity. typically 0.*9W/mK.

7. INERTNESS: cenospheres/HG-spheres can be utilized in solvents, organic chemicals water, acids or alkalis while maintaining their integrity.

8. THERMAL STABILITY: Because cenospheres are formed in the boilers, they are thermally stable in temperatures exceeding ***0C.

9. INSULTATION: Can be used in electronic filling and sealing materials, instrument boards, switches, etc.

*0. COST EFFECTIVENESS: cenospheres are *****0 less expensive than man-made hollow glass spheres, in comparison to less expensive fillers.

Main Usage of cenosphere

1.     Paints and ink: ink, bond, vehicle putty, insulating, antiseptic, fireproof paints.

2.     Plastics: the products of POM ,PA,PBT,PET,PP and so on. Like panels, boards, vehicle decorations, glass fiber products.

3.     Rubber: floors,boards ,wires and lines ,insulating devices, sole, conveyer belt, vehicle parts and bodies, fender-guard, etc.

4.     Construction materials: fire and water-proof materials, processed asphaltum, high-level road pavement, concrete repair materials.

5.   Encapsulation material: transformer filling material ,electric encapsulation material, electric encapsulation materials.

6.     Glass steel products: glass steel furniture, boats, etc.

7.     Space or military products: explosives, invisible paints for planes, ships and even soldiers, heat and compression insulating compounds, deep-water submarine.**0/mt
