Cerium Oxide Lapping Film

Overview

Cerium Oxide Lapping Film is a high-performance abrasive film designed for final-stage polishing of optical components, glass substrates, and fiber optic connectors. It utilizes precisely graded cerium oxide (CeO₂) particles coated onto a durable polyester backing, providing superior polishing performance, low scratch potential, and high surface clarity.

Commonly used in industries such as fiber optics, precision optics, photonics, and display glass finishing, Cerium Oxide Lapping Film is ideal for achieving high-gloss, defect-free surfaces.

Key Specifications

• Abrasive Material: Cerium Oxide (CeO₂)

• Backing: High-clarity PET film

• Film Thickness: 75μm standard (±5%), customizable

• Grit Sizes (Micron): 0.5μm, 1μm, 3μm, 5μm, 6μm

• Adhesive Option: With or without PSA (Pressure-Sensitive Adhesive)

• Formats: Sheets, discs, rolls, and custom die-cut sizes (1mm–350mm)

• Color: Light pink, beige, or orange (depending on grit and type)

Applications

Cerium Oxide Lapping Film is widely used for:

• Fiber Optic Connector Final Polishing (MPO, MTP, LC, SC, MT)

• Glass Surface Polishing: Optical lenses, display panels, prisms

• Waveguide & Photonic Chip Finishing

• Zirconia & Ceramic Component Polishing

• Surface Defect Removal & Scratch Repair

• Final polishing of optical-grade surfaces

Benefits

• High Clarity Finish: Ideal for mirror-like surface results

• Low Scratch Risk: Soft yet effective abrasive action

• Fast Final-Stage Polishing: Efficient for glass and ceramic materials

• Consistent Particle Distribution: Reliable, uniform surface quality

• High Compatibility: Works well with polishing slurries and lubricants

Polishing Process Example

For Fiber Optic Connector Final Polishing:

1. 30μm Diamond Film

2. 9μm Diamond Film

3. 1μm Diamond Film

4. 0.5μm or 0.2μm Cerium Oxide Film (final polish)

For Optical Glass or Display Panel Polishing:

1. 5μm → 3μm Cerium Oxide Films

2. Finish with 1μm CeO₂ Film for high gloss and clarity
