Product Introduction
UNIBEADS with a refractive index of 2.2
Features
- These glass beads are suitable for use in closed-type retroreflective materials, where the glass beads are embedded within a resin layer.
- With a high refractive index of 2.2, they maintain retroreflective performance even when covered by the resin.
- Closed-type retroreflective materials are commonly used in traffic signs, license plates, and other applications requiring high visibility.
