Our Aluminum Oxide Lapping Film is a high-performance polishing solution designed for precise surface finishing across a wide range of materials. Made by evenly coating micron and sub-micron alumina abrasives on a strong polyester film, this product delivers consistent cut rates, excellent surface finishes, and extended service life. Ideal for fiber optic connector polishing, dental tools, and high-hardness materials, it is suitable for both dry and wet lapping operations in demanding industrial settings.
Product Features
Consistent Surface Finish with Micron-Grade Alumina Particles
The precision-coated aluminum oxide ensures repeatable, controlled polishing, reducing variability and improving finish quality on ceramic, metal, and optical components.
High-Strength Polyester Film Backing for Dimensional Stability
A durable and flexible polyester backing enhances handling, flatness, and tear resistance—essential for high-precision applications like fiber optic connector polishing.
Excellent Grinding Efficiency with Minimal Surface Damage
Delivers rapid material removal while maintaining surface integrity, making it ideal for applications requiring both productivity and accuracy.
Versatile Wet or Dry Application for Flexible Use Cases
Suitable for use with water or oil lubricants, or for dry polishing, this film adapts easily to varied processing environments and tooling setups.
Stable Product Quality for Batch-to-Batch Reliability
Manufactured under tight quality control standards, the film offers reliable performance across production runs, reducing the need for rework and downtime.
