Home - Glass Beads Product Portfolio | RBH Ltd Glass Beads High performance silica based spherical glass beads used as inert functional fillers to improve flow, surface finish and dimensional stability in coatings, composites and plastics formulations. CAS NUMBER: 65997-17-3 Request A Sample Names Glass Beads | Spherical Glass Media | Soda Lime Glass Beads Chemical formula SiO₂ Product Overview Glass beads are solid, spherical inorganic particles produced from silica based soda lime glass and supplied in controlled particle size distributions. Their rigid, inert nature and smooth spherical morphology make them suitable for use as functional fillers in coatings, composite systems and thermoplastic formulations. In coatings, glass beads are used to support controlled flow behaviour, surface finish and wear resistance without significantly increasing viscosity. In composite and plastics systems, their spherical geometry aids processing by improving filler packing efficiency and contributing to dimensional stability while maintaining mechanical integrity. Selected grades may be supplied with surface treatments to improve compatibility with specific polymer matrices. Glass beads are used where predictable processing behaviour, inert filler performance and consistent end-use properties are required.
