Glass beads

Product characteristics

Glass beads also known as glass microbeads are one of the most popular and pure, mineral, non-metallic abrasives. Dust generated in abrasive blasting is free of respirable crystalline silica (SiO2) and does not cause a hazard to workers and the environment. Glass beads are reusable abrasive. As a filler glass beads lower the shrinkage of coatings while drying, improve their smoothness, flow properties and wetability. Glass beads have also decorative values.

Glass beads are used in compressed air dry- and wet-blasting applications., produce a much smoother and brighter satin finish, polishing, deburring and uniforming the surface of steel, stainless steel, non-ferrous metals, aluminium, stone. Glass beads are used for shot peening - improving the stress-resistance of metal products. Glass beads are also used as a filler in chemical and construction branch and for road marking as high reflective microbeads.
