traffic safety--New glass bead reflective material reflective belt

1. refraction index: 1.93
2. size:10-106 um
3. brightness over 550 for high intensive grade reflective sheet

Because of the perfect characteristics of  retro-reflection, the  high  refractive  index  glass  beads of ND1.93 series can be used for reflective sheets, such as high-intensive grade, engineering grade, commercial (economic) grade, number plate grade, which used in the fields of billboards, traffic sign boards, vehicle number plates, reflective stick sheets or industrial safe sign boards and so on.
