Drop on glass microsphere(EN1423) standard glass beads are made of glass as raw materials, processed by special processes and high quality glass beads.
The use of drop on glass microsphere(EN1423) standard glass beads has greatly improved the safety factor of road traffic, which plays an important role in road safety.
With micro glass beads refraction principle, in night car headlight beam is reflected back into their line of sight, which formed the marking shiny effect, these beads not only enhances the visibility of night road marking, and on the whole increased the service life of the marking.
