Road reflective glass microbeads are extraordinary tiny glass spheres crafted through the high-temperature melting of glass sand (recycled glass) as the raw material. Under a microscope, they appear as spherical, colorless, and transparent gems. Their refractive index spans from 1.50 to 1.64, and they boast diameters ranging typically from 44 microns to 1400 microns. In China, the leading method for producing these beads is the flame floating process. As a pivotal reflective material in road markings, these luminous microbeads significantly enhance the anti-reflective properties of road paint, thereby boosting nighttime driving safety, a fact attested by transportation authorities worldwide. When a vehicle travels at night, headlights illuminate road markings embedded with these glass microbeads, causing the light to reflect back in parallel. This reflection enables drivers to clearly discern their travel path, tremendously improving their night driving safety. Today, reflective glass microbeads are indispensable in road safety solutions.
