Glass beads 10 (200–300)

Glass beads (microspheres) are inert and chemically stable abrasives designed for fine blasting, sandblasting, and final surface finishing. It is made from fused glass with a high silica (SiO₂) content, which gives it high hardness, long service life, and gentle action on the treated surface.

Glass beads are ideal for applications requiring precision, a smooth finish, and minimal material wear —such as on stainless steel, aluminum, non-ferrous metals, or glass.

Glass beads properties:

• Gentle on the surface: suitable for fine finishing
• Free of harmful substances: safe for users
• Recyclable: ideal for closed-loop blasting systems
• Suitable for both injection and pressure sandblasters

Application specifications:

• Polishing and cleaning aluminum and other non-ferrous metals
• Glass sandblasting —creating a frosted finish
• Fine blasting of stainless steel surfaces
• Final surface finishing for a flawless appearance
• Uniformity and homogenization ofsurfaces
• Polishing defects from electrogalvanized zinc coatings
• Material surface strengthening (shot peening) —without the use of steel abrasives

Advantages of glass beads:

• Precise and gentle blasting, without damaging the surface
• Ideal for closed-loop blasting systems with the option to recycle the abrasive
• Gentle on the material —ideal for fine surface finishes
• High wear resistance and long service life

Glass beads are suitable for:

• Stainless steel
• Aluminum and non-ferrous metals

Note: Glass beads are not suitable for removing larger contaminants, powder coatings, or deep rust. They are best suited for fine blasting, polishing, and matting surfaces. Upon impact, glass beads do not abrade the material like corundum, for example, but create micro-indentations that do not damage the surface but rather strengthen it. The resulting surface thus appears glossy and less porous.
