The 3M™ Microfinishing Film 362L quickly cuts, shapes and polishes, delivering high-tolerance finishes. Trust it to effectively finish a variety of a wide range of industrial components that require a close tolerance. It features a 3 mil film backing and a Type S (smooth) backsize coating. Micron-graded aluminum oxide mineral achieves a uniform finish on metals, plastics and composites. Built for Microfinishing and Precision Manufacturing On flat parts such as aluminum oxide die castings, and cylindrical or contoured tooling and machine parts — consistent and predictable finishes are key. 3M™ Microfinishing Film Belt 362L helps produce smooth finishes and achieve close tolerances by way of a smooth, consistent film backing and micron graded aluminum oxide. The abrasive mineral is uniformly distributed over the backing, which helps produce a consistent finish each time you sand. Recommended substrates for this precision abrasive are finishing on metal, plastic and woodworking applications that demand precision. Smooth, High-Strength Polyester Backing Compared to conventional cloth and paper backings, the uniform smoothness of film provides a far more consistent substrate for the precise application of resins and micron-graded mineral. The high-strength 3 mil polyester backing is helpful when close tolerances are important. Micron-Graded Aluminum Oxide 3M engineers the 3M™ Microfinishing Film Belt 362L by adhering micron-graded aluminum oxide mineral to the film backing with a resin bond. In order to achieve an extremely consistent scratch for high tolerance applications, 3M uses micron-graded mineral, which is measured at a very tight tolerance for size. The resin bond ensures reliable, durable performance. The 3M™ Microfinishing Film Belt 362L features precision, micron-graded aluminum oxide, which is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges. Due to its fast cut-rate, hardness, and strength, it is widely used for sanding and finishing applications. 362L film belt is available in a variety of grades, so operators can tailor the grade to their part.
