Our road reflective glass microbeads are precision-engineered small glass spheres, crafted through high-temperature melting of recycled glass sand. Under the microscope, these microbeads reveal their spherical, colorless, and transparent nature, boasting a refractive index ranging from 1.50 to 1.64 and diameters generally spanning from 44 microns to 1400 microns. In China, the prominent flame floating method is utilized in their production. These luminous gems serve as a pivotal reflective material in road markings, amplifying the anti-reflective quality of coatings and significantly boosting night-time driving safety. As headlights illuminate road markings embedded with these glass microbeads, they reflect the light back parallel, guiding drivers safely through the night. Today, reflective glass microbeads stand as an indispensable element in road safety innovations worldwide.
