Application areas

  • Dry blast abrasive
  • Filling beads
  • fine blasting media
  • Reflex glass beads

Glass beads are a mineral, iron-free reusable abrasive with a wide range of applications. Due to their (round) grain shape, they have a low abrasive effect and are therefore ideally suited for a gentle cleaning. Our customers appreciate the special ability of the glass beads to create a silky matte surface finish. We will be happy to help you.
