Glass Beads For Industrial Purpose

Glass Beads For Industrial Purpose smooth, brilliant surface, chemically inert, widely used in wet or dry method for prest Glass beads abrasive with their hardness and spherical form can remove impurities and metal oxides without damaging the treated surface. Glass does not react chemically with other material so that the micro-beads do not create any corrosion on the treated surfaces with no deposits of foreign substances.
