Reflective Glass Spheres for Road Marking with Refractive Index 1.53-1.93 and 30% Increased Utilization Rate
Glass beads serve as high-performance, organic materials that reduce surface adsorption of dust in the air. Due to the inclusion of specific coupling agents, these beads enhance cohesive force with coatings, preventing tiny glass beads from sinking into the coating. Their flotation functionality allows them to remain on the surface, providing a larger reflective area and increasing utilization rates by over 30%. Reflective glass beads have become an indispensable material in road safety products.
We provide glass beads with various refractive indices including 1.53, 1.72, and 1.93. Our products comply with multiple international standards and can be customized according to customer-specific size distribution requirements.
