3M Microfinishing PSA Film Disc 268L, 15 Mic 3MIL, Type D, 5 in x NH, Die 500X, 25/Bag, Case of 500

• Fast-cutting aluminum oxide mineral provides a uniform finish
• May be run wet to reduce loading and airborne residue
• May be used on a variety of substrates, including metals, hardwoods and softwoods
• Pressure Sensitive Adhesive (PSA) backing for easy attachment to abrasive tools
• Tear resistant disc withstands heavy usage, prolonging abrasive service life

The 3M Microfinishing PSA Film Disc 268L features micron-graded aluminum oxide mineral, which is bonded to a durable polyester film backing, to produce a fast cut-rate and uniform finish on wood, solid surface composites, metals, plastic and fiberglass.

Flexible and Tear-Resistant
Our 3M Microfinishing PSA Film Disc 268L is a resin-bonded disc that has great flexibility and won't sacrifice durability and reliable performance. To complement the effective cut of the aluminum oxide mineral, the polyester film backing flexes to help achieve a consistent finish over contours and offers greater tear-resistance than comparable paper products, making it ideal for high-production environments.

Benefits of Aluminum Oxide Mineral
We gave these discs precision, micron-graded aluminum oxide, which is a popular choice among industrial professionals because of its fast cut-rate and long life. Due to its fast cut-rate, hardness and strength, aluminum oxide is widely used in grinding, sanding and finishing applications. Aluminum oxide is suitable for many materials in both woodworking and metalworking, including ferrous alloys. This disc is ideal for sanding plastics, paint, e-coat and wood, as these projects often require an abrasive that will maintain the integrity of the underlying workpiece. Its uniform cut and soft scratch pattern help prep the workpiece for fresh paint or other coatings.

Pressure Sensitive Adhesive (PSA) for Easy Attachment
We included pressure sensitive adhesive (PSA) in our 3M Microfinishing PSA Film Disc 268L for easy attachment to abrasive tools. The PSA backing holds the disc securely in place during use, and removes cleanly from the backup pad (sold separately), leaving an uncontaminated surface for the next sheet or disc. Designed for use with orbital and random orbital sanders, this disc comes in a range of micron grades for complete multi-step sanding and finishing. The polyester backing on 3M Microfinishing PSA Film Disc 268L is water resistant, so the disc may be run wet if desired. Adding a lubricant like water can help minimize build up and wash away unwanted swarf. The benefits are threefold: preventing clogging, keeping the mineral sharp and helping the abrasive run cool.

Our 3M Microfinishing PSA Film Disc 268L is commonly used in the marine, transportation & heavy equipment, paint preparation, AOEM and woodworking industries. Given that it effectively finishes workpieces without sacrificing part geometry, it's a great disc to have on hand.

3M Microfinishing PSA Film

The 3M Microfinishing PSA Film Disc 268L offers a fast-cutting aluminum oxide mineral that delivers a uniform finish. This disc is designed with a durable polyester film backing, ensuring both flexibility and tear resistance for reliable performance.

Its Type D format and 15 Mic (3MIL) thickness make it suitable for various sanding tasks. The 5 in x NH size fits many abrasive tools, making it a versatile choice for professionals.

Fast Cut-Rate Mineral

This disc features a micron-graded aluminum oxide mineral known for its fast cut-rate and long life. The mineral works well on metals, hardwoods, softwoods, and composites, providing a consistent finish without damaging the workpiece.

Aluminum oxide is ideal for sanding plastics, paint, e-coat, and wood, helping prepare surfaces for fresh coatings. Its uniform cut and soft scratch pattern maintain the integrity of the underlying material.

Pressure Sensitive Adhesive Backing

The Pressure Sensitive Adhesive (PSA) backing on the 3M Microfinishing PSA Film Disc 268L allows for easy attachment to abrasive tools. It holds the disc securely during use and removes cleanly from backup pads, ensuring quick changes and minimal downtime.

This PSA backing is compatible with orbital and random orbital sanders. The adhesive system supports multi-step sanding and finishing processes, enhancing productivity in various applications.

Flexible Tear-Resistant Design

Thanks to its polyester film backing, this disc is flexible and tear resistant, standing up to heavy usage in high-production environments. The backing flexes to maintain a consistent finish over contours without sacrificing durability.

This design extends the abrasive service life compared to paper-backed discs. It’s especially useful when working on complex shapes or surfaces that require precision sanding.

Pack Size And Dimensions

The 3M Microfinishing PSA Film Disc 268L comes in a pack of 25 discs per bag, with 500 discs per case. This large quantity supports continuous use in busy workshops or industrial settings.

Each disc measures 5 inches in diameter with an NH arbor hole, fitting a wide range of sanding tools. The 15 Mic (3MIL) thickness ensures durability while maintaining flexibility for various tasks.
