Product Description
2.4-2.6g/cm³ Glass Beads For Road Marking ≥650kg/cm³ For Expressways
Glass beads are used as high-performance, organic materials applied externally to enhance road marking visibility. These beads reduce surface adsorption of dust in the air due to containing specific coupling agents that improve cohesion with coatings. This prevents tiny glass beads from sinking into the coating, allowing them to float on the surface where they provide maximum reflectivity. With their large surface area, these reflective glass beads increase utilization rates by more than 30%, making them an irreplaceable reflective 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 according to customer-specified size distributions.
