Tailored to Fit: Picking Mineral, Grade and Density Scotch-Brite™ EXL Unitized Block comes in a few variations, making it easy for operators to find an abrasive tailored to their application. Unitized densities, for example, range from 2 to 8. Likely, a density of 2 is a good choice when trying to keep part geometry intact. Flexible and soft, low-density abrasives tend to conform better to the workpiece. Conversely, if a workpiece requires a stiffer, harder abrasive, a density of 8 may be a better choice. Priorities shift depending on the workpiece and application; we created the unitized block in a few different densities for these reasons. In addition to densities, operators can choose from different grades of aluminum oxide and silicon carbide. Aluminum oxide is a synthetic mineral known for its high cut-rate, hardness, strength and low heat retention. It is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys. Silicon carbide is used for creating different aesthetic finishes. It tends to wear faster than aluminum oxide but leave brighter finishes. Built for Strength Scotch-Brite™ EXL Unitized Block does offer uniform benefits, including durability and consistency. Unitized products are produced by compressing and curing multiple layers of abrasive material together. The tough and layered unitized construction gives the abrasive more durability, helping it resist wear and stand up to tough areas like edges and contours. The Many Benefits of Scotch-Brite™ Abrasives Altogether, nonwoven technology makes our Scotch-Brite™ industrial abrasives unique. A combination of fiber strands, resin, and abrasive mineral forms a thick, open web. The spring-like nature of the fibers responds to contours and effectively removes unwanted burrs, soils, and contaminants while maintaining the geometry of the workpiece, which in turn reduces rework and boosts productivity. Gaps in the web allow swarf to escape, so debris does not clog the mineral. Fibers in the web continually break down with use to reveal fresh mineral for consistency, sharp cut and long service life. From aesthetic finishing to weld blending, deburring, and more, Scotch-Brite™ abrasives work fast and deliver consistent results, part after part.
