Immerse yourself in the world of road safety with our high-quality road reflective glass microbeads. Meticulously crafted through a process of high-temperature melting of recycled glass sand, these microbeads are a marvel of engineering. Under the scrutiny of a microscope, they reveal their spherical, colorless, and transparent perfection, boasting a refractive index between 1.50-1.64 and a versatile diameter range of 44 to 1400 microns. Made predominantly through the sophisticated flame floating method in China, these microbeads play a crucial role as reflective agents in road marking paints. Their luminous presence drastically enhances the anti-reflective properties of road markings, significantly boosting night-time driving safety. As headlights illuminate the road markings, these microbeads reflect the light back with precision, clearly delineating the path ahead and ensuring a safer journey. Acknowledged globally by transportation authorities, reflective glass microbeads are indispensable assets in road safety products.
