Glass granules
Application areas
- Dry blast abrasive
- Filler
- fine blasting media
- Wet blast abrasive
Our glass granules are popular for fine blasting work on wood and facades. Due to their angular grain shape, glass granules behave more abrasively than round glass beads in the blasting process, but are considerably gentler than the various grades of alumina. We will be happy to help you.
