3M™ polishing film belt 971X was engineered as an economical alternative to conventional polishing processes. Conventional polishing processes may be messy, requiring multiple steps and compounds to get the job done effectively. The micron graded aluminum oxide mineral and film backing work together to polish the workpiece in fewer passes and with less mess. 3M™ polishing film belt 971X comes in narrow belt converted form. That means it is especially equipped to polish parts with narrow widths. It's commonly used for roll finishing, superfinishing and other fine polishing industrial applications. 3M™ polishing film belt 971X is a flocked abrasive, which means the fibers are electrostatically coated to the film. Micron graded aluminum oxide is adhered to the film backing with a slurry coating. Slurry coated abrasives have abrasive mineral embedded in the resin that binds the mineral to the backing. A slurry coated abrasive tends to produce a finer finish than coated products in similar grades, because - rather than standing straight up or protruding the minerals lie inside the resin. A slurry coated abrasive offers two fold benefits. As the mineral is not protruding, the abrasive delivers a finer and softer finishes, grade for grade. Additionally, the slurry coating can take the place of compounds and lubricants, minimizing mess. Instead, this belt can be run with water to keep both the abrasive and the workpiece cool. Aluminum oxide mineral on the 971X gives it the ability to cut fast and finish fine. Popular among industrial professionals, aluminum oxide is a versatile synthetic mineral that can be used on a variety of substrates in both woodworking and metalworking. 3M™ understands that every application from initial deburring to final polishing is integral to your work. That's why each polishing film features a unique combination of backing and mineral tailored to meet your application and to produce consistent, uniform results. Moreover, these films are available in many converted forms. 3M™ polishing film belt 971X is one of many polishing films designed to help you achieve a lasting gleam with less mess in less steps. 3M™ 7010359962, 40 in Belt Length, 4 in Belt Width, 1 micron Grit, Aluminum Oxide Abrasive, Film Backing, Green, Applicable Materials: Metal and Wood, 5 mil Backing Weight, Wet Wet/Dry Operation
