Our Aluminum Oxide Lapping Film offers exceptional consistency and durability for precision polishing across fiber optic connectors, ceramics, metals, and more. Engineered with micron-graded alumina abrasive on a durable polyester backing, this film provides uniform surface finishes, high cut rates, and long service life. It is an ideal and cost-effective alternative to 3M 261X lapping film, suited for both dry and wet polishing applications.
Product Features
Micron-Grade Aluminum Oxide Abrasive
Each film is uniformly coated with micron and sub-micron alumina particles to ensure accurate, repeatable surface finishes with minimal variation.
High Grinding Efficiency and Long Service Life
Designed for industrial-grade usage, the film maintains a consistent cutting rate over time, reducing the need for frequent replacements.
Durable Polyester Backing with Excellent Flexibility
The high-strength PET film backing resists tearing while remaining flexible enough to adapt to complex shapes during lapping and polishing.
Stable Quality with Tight Tolerances
Manufactured under strict quality control, it delivers high lapping consistency, especially important in applications like fiber optic connector polishing and dental tool finishing.
Versatile for Wet or Dry Polishing
Compatible with both water-based and oil-based lubricants, as well as dry polishing environments, to suit various industry needs.
