introduction of reflective glass beads
Glass beads are developed in recent years, a wide range of uses, a special performance of a new type of material. The product is borosilicate raw materials from high-tech processing, particle size of 10-250 microns, wall thickness 1-2 microns. The product has the advantages of light weight, low thermal conductivity, high strength, good chemical stability, etc. Its surface is specially treated with lipophilic and hydrophobic properties, which is very easy to disperse in the organic material system.
Glass beads are used in the derusting of aerospace machinery, zebra crossing of urban traffic routes, night light reflections on double yellow lines, and night light reflections on traffic signs.
