Road reflective glass microbeads are ingeniously crafted tiny glass spheres forged from the high-temperature fusion of glass sand, utilizing waste glass as a key raw material. Under the discerning eye of a microscope, they reveal their spherical, pristine, and translucent nature, boasting a refractive index ranging from 1.50 to 1.64 and diameters spanning between 44 microns and 1400 microns. In China, the predominant production method is the advanced flame floating technique. Serving as an essential reflective component in road marking paints, these luminous beads significantly elevate the anti-reflective properties of road markings, thereby enhancing night driving safety—a fact endorsed by transportation authorities globally. During nighttime driving, when headlights illuminate road markings embedded with glass microbeads, the light is ingeniously reflected back parallel, granting drivers a clear view of their path and markedly boosting night driving safety. Today, reflective glass microbeads stand as a nonpareil reflective material in road safety products.
