Hollow Glass Microspheres (HGMs) are micron-sized, smooth-surfaced spherical bubbles made primarily from soda-lime borosilicate glass. Under a microscope, they appear as hollow, transparent spheres.
These microspheres exhibit a wide range of properties, including low density, high strength, low thermal conductivity, high wave transmission, electrical insulation, heat resistance, and corrosion resistance to acids and alkalis.They also offer excellent flowability and chemical stability, making them a versatile, cutting-edge new material with applications across various fields.
The application of hollow glass microspheres facilitates performance enhancement and optimization in various materials. It plays a significant role in material lightweighting and is of great importance to energy conservation and emission reduction strategies.
