GSR Series (Soda Lime-Rotating Oven)

High Quality solid Glass spheres.
Made from superior quality raw material (Soda Lime)
Produced using state of the art Rotating ovens.

The unique rounding, washing, polishing and sieving process has been developed by our European parent company over the past 40 years. The environmental friendly process eliminates the use of products such as Hydro-fluoric acid to give our beads a very shiny but uncontaminated surface.

Advantages
  • Chemically inert
  • Consistent quality
  • High polished surfaced
  • High roundness with no sharp edges
  • Low abrasive wear
  • Narrow ranges
