3M 7000044824 Silicon Carbide Lapping Film Disc 8 in

Product Description

The 3M 7000044824 is a PSA-backed lapping film disc engineered for fiber optic polishing and other precision finishing applications. The abrasive layer consists of silicon carbide mineral coated onto a 3 mil polyester film substrate, delivering a consistent cut rate, predictable finish quality, and repeatable service life across production runs. At 8 inches in diameter, this disc mounts directly to compatible backing pads via its pressure-sensitive adhesive. Weighing just 0.02 pounds, the disc is lightweight and designed for high-volume polishing workflows where dimensional consistency and abrasive uniformity are critical.

This lapping film disc is suited for fiber optic connector end-face polishing as well as other fine-tolerance surface finishing tasks in electronics, optical, and precision manufacturing environments. The tight particle size distribution of the silicon carbide abrasive ensures minimal scratch variation between discs, making it a reliable choice for processes requiring repeatable surface quality. It is part of the 3M 466X Lapping Film series, which is also available in sheet and roll form for alternative application setups.

Key Features

• Silicon carbide abrasive on a 3 mil polyester film for consistent cut rate and finish
• PSA backing for quick, secure attachment to compatible backing pads
• Tight particle distribution minimizes surface finish variation
• 8 inch diameter suits standard lapping and polishing fixtures
• Lightweight construction at 0.02 pounds per disc
• Part of the 466X series, available in discs, sheets, and rolls

Compatibility

Designed for use with PSA-compatible backing pads and lapping fixtures used in fiber optic connector polishing and precision surface finishing applications.

Installation Notes

Technicians should ensure the backing pad surface is clean and free of debris before applying the PSA disc to achieve full adhesive contact. Align the disc carefully before pressing down, as the pressure-sensitive adhesive bonds on contact and repositioning may reduce holding strength. Remove and discard the disc when cut rate or finish quality degrades, as lapping film is not intended to be reconditioned or re-dressed.
