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 serve as common retroreflective materials for road markings, enhancing visibility and safety at night due to their high reflectivity. Common types: BS6088A, BS6088B.

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...
