Glass Beads

​Hi-Brite Glass Beads are APAS approved and are specifically engineered to deliver superior performance on the road. Available in types B, C, D, BHR, CHR and DHR, our glass beads exceed the requirements of APAS0042.

The use of High Reflective (HR) Glass Beads is one of the most economical ways to create safer driving conditions. Only road markings that contain Glass Beads are clearly visible at night and HR beads can significantly enhance the distance of view. 

Hi-Brite Glass Beads exceed the APAS0042 requirements for Colour, Roundness and Optical Quality as set out within the current Australian standards and deliver superior durability and retroreflectivity on the road.

Hi-Brite BHR and CHR beads are proven to deliver a minimum of 450mcd/Lux, whilst Hi-Brite DHR beads will deliver a minimum of 600mcd/Lux when used in conjunction with the correct coating and applied at the correct level of film-build.

Key Facts

  • APAS certified
  • Manufactured to deliver performance exceeding Australian standards for:
    • Roundness
    • Colour
    • Optical Quality
  • High Retroreflectivity reads
  • Holistic range of beads that can be used for intermix or drop on applications
  • Can be applied with standard road marking equipment
  • Complient to EN 1423, EN 1424 and AASHTO M247 specifications
  • Aqua Lux beads comply to EN 1436 and can deliver wet retroreflectivity greater the 300MCD when applied correctly

Physical Characteristics

  • Appearance and Odour: Large particle size white powder, from 100ųm to 2mm smooth spheres, with no odour.
  • Chemical Formula: Na2SiO3 / Na2O / CaO (fused ingredients general formulae, no added heavy metal oxides)
  • Melting Point / Boiling Point: MP: >600°C (softens) BP: Not determined
  • Specific Gravity or Density: 2.5 g/cm3
  • Bulk Density: 500-1000 kg/m2. Bulk density does vary with size.
  • Solubility: Rate of solubility is dependent on environment. Presences of alkali accelerate dissolution particularly above a pH of 9. pH 7 to 9 (of a 5% slurry when left for several hours - estimated)
  • Percent Volatile: <0.5% Octanol/Water
  • Particle Size: Refer to specific grade
