1. Quartz-containing blast-cleaning abrasives

Due to its high hardness and its favourable splitting characteristics quartz sand is a reliable blast-cleaning abrasive for mechanical surface treatment. Quartz-containing blast-cleaning abrasives are available on easy terms and can be disposed of with domestic refuse in general. However, as crystalline silica can be generated and inhaled when using quartz-containing blast-cleaning abrasives, present regulations, restrictions, prohibiting stipulations and regulatory occupational limits have to be respected. Please note our blast-cleaning abrasives substitute "Stralofix" at the bottom of this page.

The following table shows selected quartz sands which are used as blast-cleaning abrasives for various applications.

2. Stralofix blast-cleaning abrasives

Stralofix blasting grits are free of crystalline silica and can be used as a substitute for quartz-containing blast-cleaning abrasives without silicosis risk. Stralofix blast-cleaning grits are synthetic mineral abrasives of melted slag or copper refinery slag.
