3M 7000044802 Lapping Film 30.0 Micron Psa 8.5x11 Sheet

Product Description

The 3M 7000044802 is a pressure-sensitive adhesive (PSA) lapping film sheet designed for precision surface finishing applications. It features aluminum oxide mineral bonded to a 3 mil polyester film substrate using a durable resin system. At 30.0 microns, this grade delivers consistent, controlled material removal on fine surfaces. The sheet measures 8.5 inches x 11 inches and is well suited for use in production and service environments where repeatable, fine-finish results are required. Licensed technicians and precision finishing specialists working on fiber optic connectors and similar components rely on this film for its dimensional stability and uniform abrasive distribution.

This lapping film is commonly used in fiber optic cable termination and finishing, as well as roll superfinishing operations. The PSA backing allows the sheet to adhere directly to flat lapping tools, glass plates, or fixture surfaces without additional adhesive or clamps. The 30.0 micron grade fits into a multi-step finishing sequence, typically used in mid-range material removal before progressing to finer micron grades. It is appropriate for both production floor use and field service applications where connector end-face quality is critical.

Key Features

• Aluminum oxide abrasive mineral for consistent, controlled cutting action
• 3 mil polyester film backing provides dimensional stability during use
• Durable resin bond system resists breakdown during wet or dry lapping
• PSA backing adheres securely to flat lapping surfaces without separate adhesive
• 30.0 micron grade suited for mid-sequence finishing steps
• 8.5 inches x 11 inches sheet size compatible with standard lapping fixtures and manual use

Compatibility

Designed for use in fiber optic connector finishing and roll superfinishing applications. Part of the 3M 266X Lapping Film series, which is available in grades ranging from 0.05 to 60.0 micron to support multi-step finishing sequences.

Installation Notes

Lapping film sheets are installed by precision finishing technicians and fiber optic splicing professionals. Before use, ensure the lapping surface or backing plate is clean and free of debris that could cause uneven abrasion or film lifting. Peel the PSA liner and apply the sheet smoothly to the lapping tool, working out any air pockets to maintain full contact. Follow your process specification for micron step sequence and apply consistent, even pressure during finishing to achieve uniform end-face results.
