Glass beads for abrasives

Glass Bead/Glass Sphere is a glass type round abrasives for sand blasting and shot blasting made of glass sand. It\'s a transparent, but appears white. Our glass bead is pure and with low silica content. Standard for Glass Beads are EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.

Glass Beads has certain level of hardness,strength and elascity, can be reused and not easy to break. Our Glass Beads has fine particle distribution and high roundness rate which make sure that surfaces of working pieces are evenly cut or polished. Also high chemical stability and clean surfaces do no harm to metal surfaces.
