217EA uses proprietary microreplication technology where micron-graded aluminum oxide particles are formed into tiny pyramids of abrasive mineral and then coated on a J weight rayon backing. As these pyramids wear, fresh, sharp mineral is continually exposed to produce a consistent cut and a predictable, fine finish. Self-sharpening pyramids start sharp, stay sharp, and run cooler than conventional abrasives. Flexible backing flows over contoured surfaces for consistent finishing. For intermediate finishing and fine polishing prior to plating or buffing. Ideal for light pressure applications, allows abrasive to break down and maintain cut and produce consistent finishes. Produces finer finishes than conventional electrostatically coated abrasives.
