SILICA FLOUR


Silica sand of high quality and purity, through a very specific grinding process, decreases its particle size and is classified to obtain granulometries of less than 100 microns.

This treatment of silica sands receives several denominations;

Silica flour
Micronized quartz
Ground silica sand

Silmin Iberica is specialized in the commercialization and distribution of silica flours, micronized quartz or high purity ground silica sand for the industry.

We sell and distribute siliceous flours, micronized quartz or ground silica sand, very pure with SIO2 contents of more than 99%. This raw material is inert and its high dielectric strength makes silica flours, micronized quartz or silica sand ground an excellent charge in electrical compounds, or as a charge, they are white and have great qualities of chemical and mechanical resistance.

The granulometric diversity that we can supply allows us to distribute the appropriate size of the product according to its final application. Our sands or micronized or ground quartz are available in distributions with sizes that vary between 10 and 100 microns, adapting to the needs of the client.


They are supplied dry, by tank truck or bagged. Silmin Ibérica ensures the logistics supply for all silica flours,quartz Micronized or ground silica sands.
