HR (High Refractive Glass Beads) grade reflective glass beads refers to the high-grade products with large particle size, high roundness, high inversion, and visible in rainy nights in the latest international standards for glass beads.
HR grade reflective glass beads are produced by a brand-new “glass melting granulation method” process, which is to melt specially formulated optical materials into glass liquid, and then draw the glass liquid into glass rods according to the required particle size of the glass beads. Due to the high temperature cutting and granulation, the glass beads produced by this process have excellent performance in terms of roundness, purity, transparency, uniformity, coating layer, etc. The retrorefraction coefficient has been greatly improved (up to ≥500mcd/lux/m2) and has a certain visibility in rainy nights, making it a veritable all-weather marking.
The production technology of this process is very complex and the equipment investment is huge. It is the most advanced glass bead production technology in the world. At present, only the United States, Germany, Russia, China and other countries have mastered this technology .
Jinan Junda can supply you this HR grade refractive glass bead for road marking paint, which is widely used in Air port, Highway and rainy and Mountain roads. It can greatly improve the security level of road markings, and overcome the defects of traditional markings. Its reflective is excellent no matter during the day or in rainy nights, which helps to make sure vehicles in line to ensure drivers’ safety.
