3M 268L Aluminum Oxide Film Disc For Consistent Finish

3M 268L 5" PSA 30 Micron No Hole Aluminum Oxide Sanding Disc on Film is a film-backed abrasive disc that delivers a precise and consistent uniform finish, so repeat passes produce predictable surface quality on every part. The disc uses fast cutting abrasives, which remove material efficiently and help keep cycle times controlled on production work. Its premium micron graded mineral provides tightly controlled 30 micron cutting action, which supports uniform scratch patterns from disc to disc. The abrasive layer is bonded to a high strength polyester film, giving a stable backing that resists tearing while maintaining consistent contact across flat and contoured surfaces. This construction is well suited for solid surface finishing, where controlled stock removal and repeatable finish level are critical. As a PSA disc, it bonds to compatible backup pads with a pressure sensitive adhesive, helping changes stay quick during sanding sequences.

Key Abrasive Disc Details That Support Production

• The 5 inch diameter disc size provides a broad sanding face, so each pass covers more area on solid surface panels and similar workpieces.
• Aluminum oxide abrasive delivers efficient cutting action, which supports steady stock removal in industrial sanding operations.
• Premium micron graded mineral at 30 micron keeps cut size controlled, which helps maintain a consistent finish from one grit step to the next.
• The high strength polyester film backing resists damage during use, so the disc maintains contact and finish quality across its service life.
• Fast cutting abrasive construction reduces time per sanding step, which supports throughput on repetitive finishing jobs and batch work.
• The PSA attachment style allows the disc to adhere to compatible pads under pressure, which supports quick disc changes between micron grades.

PSA Film Disc Setup For Reliable Sanding Results

This disc uses a pressure sensitive adhesive attachment, so it relies on a PSA-compatible sanding pad for proper mounting during operation. The no hole configuration presents a continuous abrasive surface, which lets the entire 5 inch face stay in contact across the work area during use. The high strength polyester film backing supports an even interface between the abrasive mineral and the backup pad, which helps the disc track flat across wide solid surface sections and detailed areas. Premium micron graded mineral at 30 micron maintains a controlled scratch profile, so when it is installed in a sanding sequence, the finish level is predictable from part to part. The fast cutting nature of the abrasive helps each installed disc perform consistently through its working life, supporting stable process times on production equipment.

Using 3M Film Discs In Solid Surface Workflows

Where This 3M 268L Sanding Disc Fits

This 3M 268L 5 inch PSA aluminum oxide sanding disc on film is used in abrasive disc setups where a precise and consistent uniform finish is required on solid surface materials. The premium micron graded mineral at 30 micron allows the disc to occupy a specific role within a graded sanding sequence, sitting at a defined cutting level between coarser and finer steps. In solid surface finishing, this controlled micron rating supports targeted scratch removal while preparing the surface for subsequent refinement steps. The high strength polyester film backing holds the mineral in place during contact with flat panels and shaped edges, so the disc can be used across a range of part geometries within an abrasive disc system.

How Disc Construction Supports Repeatable Finishes

The combination of fast cutting abrasives and premium micron graded mineral on high strength polyester film gives this disc a defined performance profile for industrial use. The fast cutting design removes material efficiently at the 30 micron level, which helps maintain consistent process times when multiple parts pass through the same sanding station. Because the mineral is micron graded, the scratch pattern remains uniform over the disc surface, supporting a predictable finish when operators repeat the same passes. The film backing maintains dimensional stability under sanding pressure, so the disc presents a flat and consistent cutting interface to the work. This stability aids in reducing variability between parts, especially on large solid surface panels where small inconsistencies can stand out after further finishing. The no hole layout also keeps the abrasive coverage uninterrupted across the face, giving a continuous working area during each sanding stroke.
