Glassbeads or glass microspheres are fine spherical glasses with
a diameter ranged from 1 to 1180 μ.
Owing to their chemical stability and resistance to water, heat,
acids and bases, they are developed into the most effective and
important elements in traffic safety systems.
Properties
Exhaustive refractive index of 400~500 (MCD/m2/lux),
Minimum roundness of 80%,
Exhaustive transparency,
Specific surface strength owing to their glass texture,
Best types of glass used as raw materials,
Possibility to apply chemical silicone and silane
coatings,
Capacity to improve road safety owing to their high reflection
capacity,
Ideally suited for road marking.
