Glass beads

Blasting agents

Glass beads are used as an additive in plastics and resin systems.
Glass beads have various benefits as a blasting agent. Thanks to their hardness and ball shape, they can remove dirt and metal oxides without damaging the treated surfaces. Since glass does not react chemically with other materials, the microbeads do not cause any corrosion on the treated surfaces, and therefore also no deposit of foreign material.
