#4 Glass Beads (30-40 mesh size)
RockRidge glass bead media breaks down at a slow rate and can survive multiple impacts.
This allows for continuous recycling and extended blasting time. Glass beads are chemically inert and will not leave any residue on the surface of the workpiece.
RockRidge glass beads meet all Occupational Health and Safety Administration (OSHA) requirements. RockRidge® Glass Beads do not contain free-silica and meet all ISO11126-10:200 requirements.
