Hollow glass microspheres have a hollow internal structure with a density of only 0.2-0.6g/cm³, which is 1/3 to 1/5 of that of solid glass beads. This characteristic makes them an ideal choice for lightweight materials. In the automotive industry, adding them to resin matrix to make composite materials can reduce the weight of parts by 20%-30% while maintaining sufficient mechanical strength, helping to improve vehicle fuel efficiency. In shipbuilding, the use of FRP materials containing hollow glass microspheres can reduce the weight of the hull, increase navigation speed and reduce energy consumption. These microspheres also have excellent thermal insulation performance. When added to thermal insulation coatings, they can reduce the thermal conductivity of the coating to below 0.03W/(m·K), which is suitable for the thermal insulation of building exterior walls and industrial equipment. In the production process, the hollow rate can be accurately controlled by improving the nucleation technology to meet the differentiated needs of different fields for density and strength. With the pursuit of lightweight in new energy vehicles, the market demand for hollow glass microspheres is growing at an annual rate of 15%, and the application scenarios are constantly expanding.
