BS6088(A.B), EN 1423/1424,AASHTOM247,EKorean Standard, AS/NZS
2009:2002 etc. We also can produce glass bead with the customer?
Reflective glass beads for road marking
The beads make a continuous contribution to road safety (for
drivers and pedestrians alike) with its high visible warning during
darkness, heavy rain and even fog. Glass beads have the property of
sending the incident rays back to its source. This means the light
which comes into glass bead is refracted and then reflected within
the bead, and it hits back with high efficiency to the motorists.
The glass bead is a sphere. This means any directional
stress-resistance of the bead is excellent.
High refractive glass beads
When the light illuminate on the glass beads surface, owing to high
reflective functionality, the light focuses on the special
reflective lay ,strikes the back surface of glass beads and returns
to its source. So you'll see the very bright reflective light.
According to the complex optical formula, only when the refractive
index of the glass bead more than 1.9, 2.2, the glass beads will
have excellent retro-reflective effects.
