Our road reflective glass microbeads are a revolutionary advancement in road safety technology. Created through the high-temperature melting of recycled glass sand, these compact, spherical, and transparent beads boast a refractive index ranging from 1.50 to 1.64. Their size ranges from 44 microns to a substantial 1400 microns. The primary manufacturing technique employed in China, the flame floating method, ensures superior quality. These microbeads play a crucial role in road markings by significantly enhancing the reflective properties of road paints. By improving the visibility of road markings, especially at night, they contribute to heightened driving safety, as recognized by global transportation authorities. When headlights illuminate these innovative beads, they reflect the light back parallel, giving drivers clear visibility of the road ahead and thus elevating night-time driving safety. Today, reflective glass microbeads are invaluable in the realm of road safety materials.
