3M 7100029216 Lapping Film Psa Sheet 9.0 Micron

Product Description

The 3M 7100029216 is a silicon carbide lapping film sheet designed for precision surface finishing and polishing applications. It features silicon carbide mineral bonded to a 3 mil polyester film base with a pressure-sensitive adhesive (PSA) backing for secure fixture to a flat platen or backing pad. The sheet measures 8.5 inches x 11 inches and is graded at 9.0 micron, making it well-suited for fine material removal and surface preparation where tight tolerances are required. Technicians in fiber optic connector polishing and metallurgical sample preparation rely on this product for consistent, repeatable results.

This lapping film sheet is used in fiber optic and metallurgical laboratory environments where controlled, incremental abrasion is critical. The PSA backing allows the sheet to mount flat on a polishing fixture or lapping plate without adhesive tape or clamps, maintaining a stable working surface during the polishing process. It is sold individually and is part of a product family available in 5.0, 9.0, 15.0, and 30.0 micron grades to support multi-stage polishing sequences.

Key Features

• 9.0 micron silicon carbide abrasive for fine finishing and controlled material removal
• 3 mil polyester film backing provides dimensional stability and consistent cut rate
• PSA backing mounts securely to flat platens or polishing fixtures without additional adhesive
• Standard sheet size of 8.5 inches x 11 inches fits common polishing setups
• Part of a multi-grade family (5.0, 9.0, 15.0, 30.0 micron) for sequential polishing workflows

Compatibility

Designed for use in fiber optic connector polishing and metallurgical sample preparation applications requiring silicon carbide abrasive media with PSA backing on a flat lapping surface.

Installation Notes

This sheet is applied by technicians and lab professionals to flat lapping plates or polishing fixtures. Clean the platen surface before applying the PSA sheet to ensure full adhesion and prevent shifting during use. Avoid contaminating the abrasive surface with oils or incompatible polishing compounds. Replace the sheet when cut rate diminishes or surface loading is visible.
