Road reflective glass microbeads are exquisite, precision-engineered spheres crafted from high-temperature melting of glass sand (recycled glass) as the foundational material. These beads, when examined microscopically, reveal a flawless spherical shape, devoid of color with a crystalline transparency. They possess a refractive index that ranges from 1.50 to 1.64 and vary in diameter from a minute 44 microns to a substantial 1400 microns. Dominating the Chinese production landscape, the flame floating method is the preferred technique for creating these essential road safety components. As a crucial reflective element in road marking paints, these glass microbeads dramatically enhance the anti-reflective characteristics of road markings, thus increasing the safety of nighttime driving—a fact validated by transportation authorities globally. When vehicle headlights illuminate road markings embedded with these beads, the light is reflected back in parallel, significantly improving the driver's visibility and clarity on the road at night. In today's road safety domain, reflective glass microbeads have solidified their status as an indispensable material.
