Glass micro-beads are a new type of silicate material, generally called micro-beads with a diameter of less than 0.8 mm. With the continuous development of science and technology and users' increasingly demanding requirements for product performance, the diameter of glass micro-beads has also increased. It is getting smaller and smaller, and has developed from a few millimeters to a few microns in the past, and there are more and more varieties, there are solid glass beads, hollow glass beads, colored beads, colorless beads, colored beads, and high, medium And low refractive index micro-beads. Because glass micro-beads have many unique properties, the hardness is between 1.54 and 1.50 on the Mohs scale, and they have excellent chemical resistance, impact resistance, good roundness of glass beads, uniform size, light transmission and reflectivity. Good electrical insulation and heat resistance. It has good heat insulation, sound insulation, insulation and extremely low water absorption. It is widely used in resins, plastics, rubber, paints, coatings and so on.
