3M 7010308006 Lapping Film Psa Sheet 0.30 Micron 3x8 in

Product Description

The 3M 7010308006 is a precision lapping film sheet designed for fine polishing of fiber optic connectors. It features aluminum oxide abrasive mineral coated onto a 3 mil polyester film substrate with a pressure-sensitive adhesive (PSA) backing for secure fixture to a flat lapping surface. At 0.30 micron grit rating, this sheet delivers a controlled, ultra-fine cut that produces the smooth end-face geometry required for low-loss optical connections. The PSA backing allows fast, consistent mounting without adhesive mess or shifting during use. Each sheet measures 3 inches x 8 inches and is sold individually.

This lapping film is used in the termination and polishing of fiber optic connectors in both field and shop environments. It is suited for single-mode and multimode connector finishing steps where sub-micron surface finish is critical. Typical users include fiber optic technicians, telecommunications installers, and data center cabling professionals who require repeatable, low-reflection end-face results. The 0.30 micron rating positions this sheet as a final or near-final polishing step in a progressive lapping sequence.

Key Features

• Aluminum oxide abrasive mineral for consistent, controlled material removal
• 0.30 micron grit rating for ultra-fine, final-stage fiber optic polishing
• 3 mil polyester film backing provides dimensional stability during polishing
• PSA backing allows secure, no-slip mounting to lapping fixtures
• Sheet size of 3 inches x 8 inches fits standard fiber optic polishing setups

Compatibility

Designed for use in fiber optic connector polishing applications requiring 0.30 micron abrasive film with PSA backing on a polyester substrate.

Installation Notes

Installation and use is performed by trained fiber optic technicians following standard polishing procedures. Before use, ensure the lapping fixture or backing plate is clean and free of debris to allow full PSA contact. Follow a progressive grit sequence when applicable, working down to the 0.30 micron sheet as the final or near-final step. Discard sheets that show loading, tearing, or uneven wear to maintain consistent end-face quality.
