Description

Blastrite is a specially selected and graded Platinum slag with sharp angular particles, black in colour and particularly resistant to fracturing on impact.

Application

Blastrite is used where expendable abrasives are required for on-site abrasive blasting in shipyards, steel construction, oil refineries, power stations, offshore oil rigs, and any blasting yard designed for diverse and flexible applications. The product is specially graded to optimize production whilst achieving designated surface preparation standards according to industry norms.

Advantages

• Particularly resistant to fracturing on impact.
