3M 7100016046 Lapping Film 261X 0.30 Micron Sheet

Product Description

The 3M 7100016046 is a precision lapping film sheet designed for producing uniform, controlled finishes on a wide range of substrates. Part of the 261X series, it uses precisely graded aluminum oxide abrasive particles coated onto a 3 mil polyester film backing. The sheet measures 8.50 inches x 11 inches and is rated at 0.30 micron, placing it at the fine end of the lapping film grade range. Technicians and finishing specialists use this film where tight surface tolerances and consistent finish quality are required across multiple passes.

This lapping film is suited for precision finishing applications in fiber optic connector polishing, optical component preparation, and fine surface conditioning of metal or composite substrates. The 0.30 micron grade is appropriate for final-stage polishing where a near-scratch-free surface is the target. It is commonly used in industrial, electronics, and instrumentation settings where surface finish directly affects component performance.

Key Features

• 0.30 micron aluminum oxide abrasive for fine, controlled material removal
• Precisely graded particles ensure uniform finish consistency across the sheet
• 3 mil polyester film backing provides dimensional stability during use
• Sheet size of 8.50 inches x 11 inches fits standard lapping fixtures and hand use
• Compatible with wet or dry lapping processes depending on substrate requirements

Compatibility

Designed as a precision abrasive sheet for use on various substrates including metals, composites, ceramics, and optical materials where a 0.30 micron finish grade is specified.

Installation Notes

Lapping film is installed and used by technicians performing precision surface finishing; no specialized trade license is required, but proper technique is critical for consistent results. Secure the film flat against a lapping plate or backing surface to prevent slippage during use. Inspect the film regularly during use and replace when abrasive loading or surface damage reduces finishing consistency. Follow the substrate manufacturer's recommended polishing sequence when working down through multiple micron grades.
