3M™ Microfinishing Film Belt 362L, 40 Mic 3MIL, Config

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.

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.

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.

• High-strength 3 mil polyester film backing can be run with coolant
• Micron-graded aluminum oxide mineral achieves a fast cut-rate and provides a uniform, close-tolerance finish
• Type S (smooth) backsize provides an anti-slip friction coating
• Available in 9-100 micron to help operators achieve goal tolerances
