New material glass beads 2019-04-12 Glass beads are a new type of material with a wide range of uses and special properties developed in recent years. The product is made of borosilicate raw materials through high-tech processing, with a particle size of 10-250 microns and a wall thickness of 1-2 microns. The product has the advantages of light weight, low thermal conductivity, high strength, good chemical stability, etc. Its surface has been specially treated to have lipophilic and hydrophobic properties, and it is very easy to disperse in organic material systems. Glass beads are used in the derusting of aerospace machinery, the night reflection of the zebra crossing, the no-stop line, the double yellow line of the urban traffic road, and the night reflection device of the traffic sign.
