Glass micro balls

Micro balls, or Glass micro balls. Your use of the finds as a rule, in the finishing works and in the gentle pre-treatment of the surface. It ranks among the materials, which are chemically unchanging, inert. It can be used for blasting non-ferrous metals and stainless steel, in the renovation of the aluminium products or the unification of the surface of the stainless steel materials after welding or burning. Particularly suited for delicate and final adjustments.

Glass micro balls endurance during blasting

Glass micro balls can withstand up to 10 cycles. After repeated use, the grain shrinks. Can be used repeatedly.
