Reflective Glass Beads for Road Marking with BS 6088A BS 6088B Standards and Effective Nighttime Reflection
Glass beads are used as high-performance, organic materials that reduce surface adsorption of dust in the air. Due to specific coupling agents, these beads improve cohesive force with coatings and prevent tiny glass beads from sinking into the coating. Their flotation function allows them to remain on the surface, providing a large surface area that increases utilization by over 30%. Reflective glass beads have become an irreplaceable material in road safety products.
We provide glass beads with different refractive indices including 1.53, 1.72, and 1.93. We can also supply glass beads meeting various national standards or customized size distributions according to customer requirements.
