Road reflective glass microbeads are meticulously crafted from glass sand (recycled waste glass) through a sophisticated high-temperature melting process. These exquisite glass beads boast a spherical, colorless, and transparent appearance when viewed under a microscope. With a refractive index ranging from 1.50 to 1.64, and diameters spanning from 44 microns to 1400 microns, they are a marvel of optical engineering. Predominantly produced in China using the advanced flame floating method, these beads serve as a vital reflective material in road marking paints, significantly enhancing the anti-reflective properties of coatings. Their ability to amplify visibility for night driving is endorsed by transport authorities worldwide. As vehicle headlights illuminate road markings embedded with these microbeads, light is exquisitely reflected back parallelly, empowering drivers with a crystal-clear view of their path, thus fortifying night-time driving safety. In contemporary road safety solutions, reflective glass microbeads are an essential and irreplaceable component.
