Crafted to perfection, road reflective glass microbeads are engineered using high-temperature melting of glass sand, primarily sourced from waste glass. These tiny spheres, which are colorless and transparent under a microscope, boast a refractive index of 1.50 to 1.64 and vary in diameter from 44 microns to 1400 microns. In China, the flame floating method is the predominant technique for their production. Employed as a reflective agent in road marking paints, these luminous microbeads significantly enhance the night-time driving safety by improving the markings' reflective capabilities. This reflective magic occurs when headlights hit the beads, making them shine brightly, thus illuminating the path ahead for drivers. As confirmed by global transportation authorities, these glass microbeads stand as an essential, irreplaceable component in road safety materials, ensuring superior visibility and safety for all night-time travelers.
