Bright large particle glass bead

Product Name : bright large particle glass bead

Appearance : colorless, transparent, without obvious bubbles and impurities

Roundness : ≥ 90%

Reflectivity : Nd ≥ 1.50

Density : 2.4-2.6g/cm3

Main components : SiO2 content > 68%

Size range : 850-1400 μ M

After construction, the exposed part of the coating surface is higher than that of the common surface, so the reflective performance of the marking is improved, especially for the road marking in rainy and foggy areas. Double layer bags shall be used for

Premixed glass beads
