Industrial Minerals (NZ) Ltd Glass Beads are manufactured at an ISO 9000 registered plant. Each batch of beads is tested to ensure that they meet the exact specification that this abrasive media demands.

Industrial Minerals Glass Beads are packaged in double lined bags and transported in a humidity controlled environment to ensure that they arrive in a dry, free flow, clump free, condition.

Some glass beads may be manufactured from recycled glass and consequently contain unsafe levels of contaminates. This is not the case with Industrial Minerals Glass Beads. These have been tested, by independent laboratories in New Zealand, and found to be within published TCLP parameters. Freely available elements have also been found to be within acceptable levels. Copies of all test results are available upon request.

Industrial Minerals Glass Bead customers are amongst New Zealand's Leading Industrial Companies.

As a general rule, when using glass beads:

  • The larger the bead the brighter the surface finish.
  • The smaller the bead the more matt surface finish.
  • The larger the bead the deeper the clean / peen.
  • The smaller the size the faster the clean.
  • Never blast Glass Beads over 80psi.
  • Replace worn blast parts immediately paying special attention to nozzles.
