Product Description
Reflective Glass Beads for Pavement Markings
Reflective glass beads are high-performance organic materials designed for pavement markings. The specialized coating on the beads reduces surface adsorption of airborne dust, while the specific coupling agent enhances cohesive force with coatings, preventing tiny beads from sinking due to flotation function. This results in increased surface area and over 30% higher utilization rate, making reflective glass beads an irreplaceable material in road safety products.
We provide glass beads with various refractive indices including 1.53, 1.72, and 1.93, and can manufacture according to different national standards or custom size distributions specified by customers.
