Road reflective glass microbeads are expertly crafted through the high-temperature melting of recycled glass sand, resulting in small, spherical, and transparent beads. With a refractive index range of 150-1.64 and diameters from 44 to 1400 microns, these beads are produced in China using the advanced flame floating method. As a crucial component in road marking paints, these luminous microbeads significantly enhance the anti-reflective capabilities of road coatings, thereby boosting night-time driving safety. When vehicle headlights illuminate these beads, they reflect light back in parallel, ensuring clear visibility of road directions and substantially improving night-driving safety. Reflective glass microbeads have thus become a vital and irreplaceable material in road safety applications across the globe.
