Profile: Shanghai Green Sub-Nanoseale Material Co., Ltd. produces cenosphere. We also produce zeeosphere, nanometer calcium carbonate, microcrystalline powder, glass beads, microgla glass flake and high refraction glass beads. The zeeospheres are light gray/white, light, inert and nonmetallic hollow ceramic spheres in the range from 15µm to 100µm. With N ₂ /CO ₂ inside, the material has excellent fluidity as well as sound electric and heat insulation. These are mainly used in fire and water-proof materials, processed asphaltum, high-level road pavement & in concrete repair materials. These are also used in floors, boards, wires & lines, insulating devices, sole, conveyor belt, vehicle parts & bodies and fender-guard. Microcrystalline powder is a new-type of inorganic multifunctional powdered filling material. It is of high content, good whiteness, high activity, and easy to be dyed & modified. It is anti-acid and alkali-resistant, anti-corrosion, heatproof of strong insulation, has small thermal expansion coefficiency, strong weather resistance, good suspensibility & smoothness. It has functions such as anti-solidifying and anti-cracking, ultraviolet-proof, anti-aging & reinforcement. It is the ideal new-type filler. We produce glass beads of various kinds with an annual production capacity of 3000 tons. These are used in road marking, peening processes, metal cleaning and polishing & used as filler materials in plastic, paint & rubber manufacturing. We apply the high white glass beads for arts, lamp and luxury light. The round rate of this kind of glass beads is as high as 90% and more; impurity content is very low.
