GlassBeads are bubble-free glass grinding media with a density of 2.5 kg/l. They are especially recommended for wet grinding applications in the low to medium viscosity range. This is also true for applications for which the use of high-quality zirconium oxide grinding beads is no real alternative due to the high costs.
