High Index Glass Beads For Airport Paint With Index 2.2 is very common inter standard ,TENROADS is one of the leading manufacturers to supply high index road marking glass beads,our products have sold into several market, including:Southeast area,middle east area,south Africa,Europe and so on,we always keep strictly quality standard from material to final products,so our products are accepted for market.
These glass beads require more higher retro-reflectivity,where top data is above 2.2 is required, we use special glass which is more clear and lower on heavy metal , have high reflective index and more stable performance
High index reflective glass beads are a new type of silicate material with good retro-reflectivity when the refractive index is between 1.9 and 2.2. That is, when a beam of light illuminates the surface of the bead at any angle within a certain range, it is concentrated on a specific reflective layer behind the bead due to the refraction of the bead, and the reflective layer reflects the light back in parallel along the direction of the light source.

High index reflective glass beads are the core components for the manufacture of retro-reflective new optical functional composites. Composite film materials composed of glass beads, are widely used in roads and railways, airports, ports, marine transportation, mining, tunnels, fire, urban construction and other fields as a variety of reflective signs, but also widely used in advertising, film, multimedia and other computer products projection screen.
