Road reflective glass microbeads are exquisite, spherical wonders crafted through the high-temperature fusion of recycled glass sand. These tiny, colorless, and transparent pearls, observable under a microscope, boast a refractive index ranging from 1.50 to 1.64 and a diameter spreading from a mere 44 microns to an impressive 1400 microns. In China, the revered flame floating method predominates their production. As the quintessential reflective element in road marking paints, these luminous beads significantly bolster the anti-reflective prowess of road coatings, thereby elevating the safety quotient of nocturnal driving-a fact endorsed by transportation authorities worldwide. When vehicles navigate the darkness, their headlights beam onto markings embedded with these microbeads. This interaction ensures that light is reflecting in a parallel path, empowering drivers to discern their routes with precision and enhancing night-time driving safety. Today, reflective glass microbeads are indispensable in the realm of road safety innovations, unmatched in their reflective efficacy.
