Road reflective glass microbeads are ingeniously crafted from glass sand (recycled glass) through a high-temperature melting process. These microbeads are perfect spheres, boasting a transparent and colorless appearance when observed under a microscope. With a refractive index ranging from 1.50 to 1.64, and diameters varying between 44 microns to 1400 microns, these beads are the pinnacle of precision. The predominant production method in China is the advanced flame floating technique. These luminous glass microbeads significantly enhance the reflective performance of road marking paints, revolutionizing night driving safety. Countries worldwide have acknowledged their vital role in road safety, as they enable headlights to reflect vividly, ensuring drivers a clear vision and safer journeys at night. Today, these reflective glass microbeads are indispensable in the realm of road safety products.
