3M Microfinishing PSA Film Disc 268L, 100 Mic 3MIL, Type D, 5 in x NH, Die 500X, 25/Pac, 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 exact model, 268L, features a durable polyester film backing for reliable performance in sanding and finishing tasks.

Designed for professionals, this disc’s micron-graded aluminum oxide ensures consistent results. The 3MIL thickness and Type D format make it flexible yet tough for various applications.

Uniform Cut And Finish

With a 100 Mic (micron) grade, this disc provides a precise and soft scratch pattern ideal for prepping surfaces. The aluminum oxide mineral is known for its fast cut-rate and long life, making it suitable for metals, hardwoods, and softwoods.

This grade helps maintain the integrity of underlying materials like plastics and paint, ensuring a smooth finish ready for coatings or further work.

Easy Attachment With PSA

The Pressure Sensitive Adhesive (PSA) backing on this 5 in x NH disc allows quick and secure attachment to abrasive tools. It holds firmly during use and removes cleanly from backup pads, simplifying disc changes.

Compatible with orbital and random orbital sanders, the PSA backing supports efficient multi-step sanding processes. Its water-resistant polyester backing also enables wet sanding to reduce clogging and heat buildup.

Tear Resistant Durable Disc

This 3M Microfinishing disc is tear resistant, designed to withstand heavy usage in high-production environments. The polyester film backing offers greater durability compared to paper discs, extending abrasive service life.

Its flexibility helps maintain consistent contact over contours, making it ideal for complex shapes and surfaces. The 5-inch size fits standard sanding tools for versatile use.

Pack Size And Format

Each pack contains 25 discs, and the full case includes 500 discs, ensuring ample supply for large projects or ongoing production needs. The disc’s die 500X format supports precise and repeatable sanding results.

This pack size is convenient for industries like marine, transportation, and woodworking, where consistent abrasive performance is critical. The 3MIL thickness balances flexibility and strength for reliable use.
