High Refraction Glass Beads

High-refraction reflective powder.
Reflective powder product characteristics:
　　high-refraction glass beads (reflective powder) mainly with the return of the main characteristics of reflection. The so-called return reflection is a optical phenomenon, when exposed to light lens like objects, gathered after the refraction, reflection and re-focus from the lens by the return of light refraction direction. Products using the second half aluminium-plating surface of high refractive index glass beads as a reflector to the post, which are very reverse of the retro-reflective performance, to 85% of the direct reflection of light back to the light source. The return reflection creates reflection brightness will enable the driver and the night-time operation personnel with light source at night or in the case of poor vision clearly see the pedestrian and the barrier goal, ensure both to security.
　　reflective powder is high-refraction glass beads, refractive index :nd ≥ 1.93 and nd≥ 2.2, the rate of opacity: ≤ 1%, the rate of the whole roundness: ≥ 95%, solubility:insoluble. According to the color can be divided into the white and the gray two kinds. Reflection brightness changes along with the amount of adding powder.
　　reflective powder application:
　　 reflective powder is the core composite material of a new type of optical functions,such as: reflective fabric, reflective film, reflective coatings, reflective signs, advertising materials, clothing materials, the standard field runway, shoes, hats, bags, life-saving supplies and so on.it has the characteristics of return reflection which resulting strong retro-reflective effect without additional power, can be used in areas such as: roads, ports, mines, fire etc. As the safety mark, enhanced user's security reliability greatly. Widely used in screen printing, reflective paint, reflective ink, traffic signs, reflective materials and other fields.
