Road reflective glass microbeads are remarkable creations birthed from the high-temperature fusion of glass sand, primarily sourced from recycled glass. These tiny, spherical wonders are colorless and transparent under microscopic examination, boasting a refractive index ranging from 1.50 to 1.64. Their diameters vary between 44 microns and 1400 microns. In China, the predominant method for crafting these beads is the flame floating technique. As a pivotal component in road marking paints, these luminous glass beads significantly bolster the anti-reflective capabilities of road markings, thus enhancing nocturnal driving safety. Transportation departments across the globe have acknowledged their efficacy. When vehicle headlights illuminate these bead-infused road markings at night, the reflected light guides drivers safely and clearly along their path. Today, reflective glass microbeads stand as an indispensable element in the realm of road safety products.
