Road reflective glass microbeads are ingeniously crafted from high-temperature melted glass sand (waste glass) into minuscule, colorless, transparent spheres. Under the microscope, they shimmer with a refractive index between 1.50 and 1.64, with diameters spanning an impressive range of 44 to 1400 microns. The flame floating method reigns supreme in China for producing these essential road safety components. These microbeads, integrated into road marking paint, dramatically boost the anti-reflective prowess of road coatings, significantly enhancing nighttime driving safety—a benefit acknowledged by global transportation authorities. As a car traverses nocturnal roads, its headlights cast a beam on markings infused with glass microbeads, reflecting light back in parallel and illuminating the driver's path with crystal clarity, thereby elevating the security of night journeys. Reflective glass microbeads have ascended as a nonpareil addition to road safety materials.
