Hollow Ceramic Microspheres
Hollow Ceramic Microspheres
Cooperation with the material research institution in China, We pioneer in manufacturing hollow ceramic microspheres in various sizes between 10µm to 850µm and has established an annual production capacity of 5000MTS. Due to its unique combination of hollow spherical shape, light weight, high melting point, high compression strength, good sound electrical and thermal insulation, Hollow ceramic microsphere 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.
Hollow ceramic microspheres are light gray or off-white, light, inert and nonmetallic hollow ceramic microspheres in the range from 10µm to 850µm.With N2 or CO2 inside and over 95% spheres, the material has excellent fluidity as well as sound electric and heat insulation, Hence it is called” The Space Era Material”. The hollow ceramic microspheres can be further divided into two kinds: Thin Wall Hollow Ceramic Microsphere and Thick Wall Hollow Ceramic Microsphere.

Characteristics of Hollow Ceramic Microspheres
1. IMPROVED RHEOLOGY: Hollow ceramic microspheres are nonmetallic hollow ceramic microspheres in the range from 10µm to 850µm. With the spherical shape of hollow ceramic microspheres, rheology will improve greatly for most applications.
2. LOW DENSITY: When density, counts, hollow ceramic microspheres can be the answer with a density ranging from 0.50g/cm3 to 0.80g/cm3. Compared to most ground minerals and other resins, hollow ceramic microspheres are 30-85% lighter.
3. LOW RESIN DEMAND/HIGH LOADING POTENTIAL: hollow ceramic microspheres have the lowest surface area to volume achievable. With their spherical shape, hollow ceramic microspheres produce far less viscosity.
4. HIGH COMPRESSIVE STRENGTH: hollow ceramic microspheres can greatly improve the weariness properties of the end products.
5. LOW SHRINKAGE: hollow ceramic microspheres are one of the few products in the filler industry today that can meet the requirements for low shrinkage.
6.LOWTHERMAL,ELECTRICAL,AND SOUNDCONDUCTIVITY: hollow ceramic microspheres are extremely resistant to heat and typically have a melting point in excess of 1300℃. As hollow ceramic microspheres are hollow they have a relatively low coefficient of thermal conductivity. typically 0.09W/mK.
7. INERTNESS: hollow ceramic microspheres can be utilized in solvents, organic chemicals water, acids or alkalis while maintaining their integrity.
8. THERMAL STABILITY: Because hollow ceramic microspheres are formed in the boilers, they are thermally stable in temperatures exceeding 1000℃.
9. INSULTATION: hollow ceramic microspheres can be used in electronic filling and sealing materials, instrument boards, switches, etc.
10. COST EFFECTIVENESS: hollow ceramic microspheres are 50-200% less expensive than man-made hollow glass spheres, in comparison to less expensive fillers.
Main Usage of Hollow ceramic microspheres
1. Paints﹠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.700/mt
