Grinding Glass Beads

Glass beads with the quality of clean, transparent, no bubbles and impurity. widely used in blasting, polishing, grinding etc.

Glass beads with the quality of clean, transparent, no bubbles and impurity. Its hardness and spherical form is suitable to remove impurity and metal oxides with no damaging of the treated surface. It also does not react chemically with other materials so that it widely used in blasting, polishing, grinding etc.
