IRGRIT^® is very pure and is of a consistent quality with negligible variations in the chemical composition of key constituent viz. Iron Oxide, Silica (combined), Calcium Oxide etc.IRGRIT^® for use as a blasting medium containing less than 0.5% free silica and 25ppm of chloride and for disposal based on negligible leaching out of heavy metals. Every batch of the finished product is sieve analyzed to ensure that the particle size mix is within ±10% of the recommended grading curve. 

Hardness:

IRGRIT^® has a hardness of 7 on the Moh’s scale which ensures fast and easy removal of mill scale, rust and old paint coatings from steel and concrete on steel up to the highest level of cleanliness (Sa3).

Sharpness:

IRGRIT^® is composed of multifaceted grains with sharp edges which cut into the surface ensuring fast and efficient cleaning and uniform anchor profile.

Toughness:

IRGRIT^® due to the content of Iron Oxide exhibits high toughness and low particle breakdown on impact. This characteristic combined with the dust free product results in very low dust generation during blasting.

Density:

IRGRIT^® has a high density of 3.5 which results in higher impact energy per particle (than with abrasives of lower density e.g. sand, coal slag) thereby lowering the consumption per square meter.
