Reflective powder is the high refractive index glass microsphere hemisphere aluminum, provides self-reflection layer, and less to others such as aluminum paste base, so that the beads have a self-reflective function, reflective way more effective than a bottom aluminum paddle method 4-5 times, widely used in reflective paint, reflective ink and screen printing.
High refractive glass microsphere having predominantly retroreflective properties. The so-called return reflection is an optical phenomenon, when the light shines on an object like a lens, focusing refracted, and then they return light refracted through the lens focus from reflection direction.After the products using high refractive index glass beads and a half after the surface of aluminum as the reflector, with a strong reverse retro-reflective properties, making 85% of the light directly reflected back toward the source.Reflective retroreflective brightness caused by the driver and the night allows workers with a light source in case of poor vision at night or circumstances clearly see pedestrians and obstacles to the goal, to ensure that both safety.
