Discover the marvel of road safety with our Road Reflective Glass Microbeads. These extraordinary, tiny spheres are crafted through the high-temperature melting process of glass sand, primarily derived from recycled glass. Their spherical, colorless, and transparent nature is evident under a microscope, boasting a refractive index range of 1.50 to 1.64 and a size spanning from 44 to 1400 microns. In China, the predominant method of production is the flame floating technique. As an essential reflective material in road markings, these luminous glass microbeads significantly enhance the anti-reflective prowess of road marking coatings. This enhancement is crucial for improving night driving safety, a fact acknowledged by transportation authorities worldwide. When a vehicle's headlights illuminate road markings embedded with these glass microbeads, the light reflects back in parallel, ensuring drivers can clearly perceive their path and bolstering nighttime driving safety. Today, reflective glass microbeads stand as an irreplaceable component of road safety products, underscoring their vital role in maintaining roadway security.
