Reflective Materials Glass Beads for Road Signs

Product Description

Product Description
Glass beads are made of non-alkaline sodium calcium glass materials, which have good chemical stability and mechanical strength, a hardness of 6-7 Mohs, and sufficient elasticity for repeated use.
The roundness is greater than 80%, and the particle size is uniform, which can effectively ensure that the brightness coefficient of sandblasted parts remains uniform and not easy to leave traces.
Smooth and free of impurities - appearing as spherical particles with no impurities; Smooth surface with good smoothness, meeting international and domestic standard levels.
