Hollow borosilicate glass...
The hollow microspheres in borosilicate glass are a type of inorganic, non-metallic, ultralight high performance powder for the application of...
They are used in sand blasting machines, both dry and wet, for sandblasting, shot peening and paint stripping of excellent finish:
a. The dry jet (suction or pressure air) shortens the processing time and allows to obtain high returns;
b. The wet jet makes the impact of the abrasive "softer" giving origin to finishes with minimum roughness values.

It is an abrasive, exempt from free silica and lead, obtained by solidification of tempered sodium glass. It is usually used in spherical form and more rarely in an angular form.
The Glass Microspheres are for cleaning and finishing of: molds, matrices, gears, small parts, mechanical parts, removal of oxides, deburring, aesthetic finish on stainless steel, brass, copper, aluminum, titanium, plastic, ceramic, glass and fabrics.
The use is intended for metal surfaces in order to improve their final appearance, and for the delicate cleaning of sensitive surfaces. Furthermore, being chemically inert, they do not contaminate the sanded material. They carry out their action effectively and completely so they can be used 6-10 times.
Glass microspheres are used to clean delicate pieces where the surface is not to be damaged: they do not alter the dimensions, shapes or any sharp edges of the parts subjected to treatment, leaving a surface with a minimum roughness and a softened profile.
The non-abrasive shot-peening has a good resistance to crushing and therefore makes them particularly suitable for sandblasting operations, especially in recirculation systems.
