Glass Beads
Starbead® are high quality glass micro spheres resulting from the specialised processing of selected glass cullet.

Glass Beads

Starbead® Roadmarking Beads are solid, spherical glass beads manufactured according to BS6088, Class B. The high quality glass microspheres are obtained from a specialised process using selected glass culet.

FUNCTION:
Starbead® standard glass beads are a major factor in increasing road safety in an economical manner. Thanks to the beads’ retro-reflective action at night, a vehicle’s headlight beam is returned to the driver’s eye. The microspheres not only multiply the visibility of road markings at night, but also increase the marking’s durability in general. Starbead® glass beads are used as a drop-on agent and as premix beads for roadmarking materials.
