Sinosteel Ma’anshan New Material Technology Co., Ltd is the first high-tech company that specializes in research&development, production, and sales of high-performance Hollow Glass Microspheres and lightweight composites in China. We own advanced production lines. Our R&D team consists of a number of materials Experts, PHDs, Masters, and some other researchers.
Until now, we have 12 authorized patents and 3 certified high-tech products. Our products are widely used in oil fields, functional coatings, aerospace, deep-sea floating materials, rail transportation, automotive parts, electronics, and many other industries.
Glass bubble & Hollow glass microsphere's applications are in the fields of thermal insulation coating, putty, plastic casting polyester, FRP, SMC(BMC), radome, synthetic foam, adhesives, printed circuit board substrate, RTM, bowling, fan blades, & caulking materials, emulsion explosives, golf, sealant, pipeline insulation materials, artificial marble, PVC, low-density oil drilling, light cement, and other deep-sea buoyancy, etc. Application of hollow glass microspheres in Paint Hollow glass microspheres have the smallest surface area and low oil absorption rate, which can significantly reduce the consumption of other components in paint. The vitrified surface of glass microspheres can realize the chemical corrosion resistance, and reflection on the light. Therefore, the paint can prevent fouling, corrosion, UV, yellowing, scratching, etc. Thin gas inside the hollow glass microspheres with compact arrangement, makes low thermal conductivity, so that paint coating has a very good effect on heat insulation. Hollow glass microspheres can effectively enhance the fluidity and smoothness of coating. Hollow glass microspheres contain gas inside, so it has a good contractility resistance to hot and cold, thus enhancing the flexibility of coating, greatly reducing the cracking and peeling of the coating due to thermal expansion and contraction. On-premise of high filling level, the viscosity of paint will not be significantly increased, thus reducing the usage of solvents. It can reduce toxic gas emissions in the process of painting, and the VOC indicators can be effectively reduced.
