It is a kind of new and developing grinding material with the property of high hardness, high wearability and high micro-strength. In addition, the chemical properties of Glass Beads are not active and its PH is neutral. Therefore, it is an ideal medium material for polishing, grinding and cleaning of metal and high intensity glass.
