3M 7000044784 Silicon Carbide Lapping Film Disc 5 Inch

Product Description

The 3M 7000044784 is a 5-inch diameter PSA-backed lapping film disc engineered for fiber optic polishing applications. The abrasive layer consists of silicon carbide mineral coated onto a 3 mil polyester film substrate, delivering a consistent cut rate, uniform finish, and predictable service life across repeated use cycles. The pressure-sensitive adhesive backing allows quick, secure mounting to compatible backup pads. Fiber optic technicians and precision polishing professionals install this disc when flat, controlled material removal is required on connector end-faces and similar optical surfaces.

This disc is suited for fiber optic connector polishing in telecommunications, data center, and field-termination applications. The tight particle size distribution of the silicon carbide abrasive ensures repeatable surface finish quality from disc to disc, which is critical when polishing APC, UPC, and PC connector types to meet return-loss specifications. It is sold individually and available in volume quantities for shop or field operations.

Key Features

• Silicon carbide abrasive on 3 mil polyester film backing for controlled, consistent cut rate
• PSA backing for fast, secure mounting to backup pads
• Tight particle distribution for repeatable finish and minimal end-face variation
• 5-inch diameter format sized for standard polishing fixtures
• Consistent disc life supports process control in high-volume polishing environments

Compatibility

Designed for use with PSA-compatible 5-inch backup pads and polishing fixtures used in fiber optic connector end-face preparation and lapping applications.

Installation Notes

Installation is performed by fiber optic technicians or precision polishing professionals. Peel the release liner and press the PSA face firmly onto a clean, dry backup pad before use. Ensure the backup pad surface is free of debris or adhesive residue from previous discs to maintain flat contact. Follow facility or manufacturer polishing machine guidelines for disc replacement intervals and applied load.
