Technical Data

Glass microspheres are an abrasive product without free silicon, obtained by solidifying tempered sodium glass. It is usually used in spherical form and less often in angular form. The field of application is vast, but it is mainly used for finishing metal surfaces in order to improve their final appearance. Being, unlike other sandblasting abrasives, chemically inert, it does not contaminate the sandblasted material.

Glass microspheres are used for cleaning delicate parts where the surface should not be damaged: in fact, they do not change the size, shape or any sharp edges of the parts being treated, leaving a surface with minimal roughness and a softened profile. They are particularly suitable for the deburring and pretreatment of cutting tools, surgical instruments and electronic components and for the surface finishing of glass, jewelery and dental equipment.
The good crushing resistance makes them particularly suitable for sandblasting, especially in recirculation systems.
They are also used for tempering or graining to increase the fatigue resistance of treated parts.

It can be used with free jet sandblasting, in sandblasting booths with compressed air, pressure or vacuum, both dry and wet:
- the dry jet (suctioned or pressurized air) shortens processing times and allows obtaining high yields;
- the wet jet makes the impact of the abrasive "softer", giving rise to finishes with minimal roughness values.
