Glass Beads

Glass beads are sandblasting materials made of high-quality borosilicate glass or soda-lime glass. They have chemical stability and mechanical strength and can be used for cleaning, polishing, deburring, and shot blasting. Widely used in industries that require precise surface treatment without damaging the underlying material, such as soft metals, glass, plastics, rubber, etc.
