Crafted with precision, our road reflective glass microbeads are innovative creations formed from high-temperature fusion of recycled glass sand. These miniature, spherical marvels appear colorless and transparent under the lens of a microscope, with a versatile refractive index ranging between 1.50 and 1.64. Their diameters span a spectrum from 44 microns to a substantial 1400 microns. In the heart of China, the flame floating method dominates as the leading production process for these essential road safety components. When these glass microbeads are incorporated into road marking paints, they transform into luminous beacons that significantly enhance the reflectivity of markings, thereby bolstering night-time driving safety-a claim verified by numerous global transportation authorities. As vehicles navigate the nocturnal roads, headlights illuminate these beads, reflecting light back to the driver, ensuring clear visibility and improved safety. Today, reflective glass microbeads stand as indispensable elements in the suite of road safety materials.
