Glass Beads

Glass beads, produced from crushed glass and flat glass materials, are processed into spherical shapes through high-temperature melting. Known for their low thermal conductivity, high strength, and excellent chemical stability, glass beads feature smooth surfaces, uniform sizes, high hardness, and abrasion resistance.

Properties

  • High roundness of the beads: >90%
  • Roundness: >90%
  • Refractive index (glass beads for marking): 1.5-1.9
  • Size: 0.045 to 30mm

Applications

  • Industrial applications include sandblasting, where the roundness and high purity of glass beads leave surfaces bright and polished. Common sizes: 40#, 60#, 80#, 100#, 120#, 150#, 180#, 220#.
Glass Beads
  • Glass beads serve as common retroreflective materials for road markings, enhancing visibility and safety at night due to their high reflectivity. Common types: BS6088A, BS6088B.
Glass Beads
  • Widely used in the textile industry as a common filling material for items like weighted blankets, plush toys, and eye masks. Common sizes: 0.8-1.2mm, 1-2mm, 2-3mm, 3-4mm…
  • Larger glass beads, such as 10mm/11mm/12mm, find applications in aerosol and perfume bottle mouths, bearings, and perfume sprayers.
  • Glass beads are also utilized in water filtration systems. Common sizes: 3mm±0.03, 5mm±0.03, 8mm±0.03...
