High reflective index glass beads are perfect retro-reflective materials.
They are widely used for manufacturing reflective sheet materials for
Road sign, and they are also used for reflecting cloth, billboard, screen,
airport Runways, shining painting materials etc.
May be considered as spherical lens and it can returns incoming light to
the original light source when reflecting layer is set in its focus point.
The position of focus point of the glass beads is relied on its reflective
Shaped like perfect spheres with a smooth and shinning surface.
Remarkable strength, hardness and chemical stability.
Reflective index to control it¡¯s focus point.
Uniform particle distribution.
Made of Tio2, BaO glass, and their refractive index is approximately1.93
No lead, No harmful to human.
