Product Description
Glass Beads
Glass beads are a spherical, iron-free blasting medium. Taking hardened spherical soda lime glass as raw materials, glass beads are a multi-faceted and commonly used media. Micro glass beads are one of the most common reusable blasting media, which is ideal for non-aggressive cleaning and for producing visually attractive surfaces.

Advantages
Does not cause dimensional change to the base material
Environmentally friendlier than chemical treatments
Leave even, spherical impressions on blasted part surface
Low breakdown rate
Lower disposal & maintenance costs
Soda Lime glass does not release toxins (no free silica)
Suitable for pressure, suction, wet and dry blasting equipment
Will not contaminate or leave residue on work pieces
Applications
1. Blast-cleaning–removing rust and scale from metallic surfaces, removing mould residues from casting and removing tempering colour
2. Surface finishing–finishing surfaces to achieve specific visual effects
3. Used as disperser, grinding media and filter material in day, paint, ink and chemical industry
