Glass microspheres for high-refractive-index (RI 1.93) reflective sheeting

Reflective materials, with their bright colors during the day, provide conspicuous visual warnings. At night or in low‑light conditions, their luminous reflective properties effectively enhance visibility, enabling drivers and pedestrians to clearly identify objects, remain alert, and thereby prevent accidents, reduce casualties, and minimize economic losses. As an indispensable safety safeguard on roadways, they deliver significant social benefits.

Reflective‑film glass microspheres are made from high‑refractive‑index glass and exhibit excellent retroreflective performance. The products meet the optical‑performance requirements of the EN 20471 standard and comply with material‑safety standards such as REACH, OEKO‑TEX, and EN 71 for toys. Reflective fabrics—such as reflective cloth, reflective yarn, and reflective tape—are manufactured using these microspheres and are widely employed in personal safety and civilian protective‑wear applications. They feature spherical particles with smooth surfaces, a stable refractive index that facilitates precise focal‑point control, and a uniform particle‑size distribution. Made from titanium‑barium glass, they are lead‑free and harmless to humans.
