Lapping Film Product Line — Full Specifications
Diamond Lapping Film — 0.5 to 30 Micron
Monocrystalline and polycrystalline diamond lapping film for the hardest materials: fiber optic connector endfaces, ceramics, sapphire and tungsten carbide. Tight particle-size distribution keeps scratch depth predictable from batch to batch — the reason connector factories standardize on diamond film for final polish. 1 micron lapping film and 3 micron diamond lapping film sheets and discs are stocked for fast shipment.
| Abrasive | Monocrystalline / polycrystalline diamond |
| Micron grades | 0.5, 1, 2, 3, 6, 9, 15, 16, 30, 40, 45, 60, 80 μm (#10000 to #180) |
| Backing | Polyester film, with or without backing |
| Formats | Sheets, discs and rolls |
| Typical applications | Fiber optic connectors, ceramics, carbide, sapphire |
Aluminum Oxide & Cerium Oxide Lapping Film
Aluminum oxide lapping film (AO) covers general lapping and pre-polish from 0.3 to 30 micron; cerium oxide film (CO) delivers the final optical-grade finish on glass. Together they form the standard sequence for optical component lapping, metallography and fiber polishing where diamond is not required — at a significantly lower cost per polish step.
| Abrasive | Aluminum oxide (AO) / cerium oxide (CO) / silicon carbide (SiC) |
| Micron grades | AO 0.3 to 40 μm (11 grades) · SiC 1 to 30 μm (7 grades) · CO 0.3 and 0.5 μm only |
| Backing | Polyester film, with or without backing |
| Formats | Sheets, discs, rolls |
| Typical applications | Optical glass, lenses, metallographic prep, fiber optics |
Microfinishing Film Rolls for Production Lines
Precision microfinishing film (microfinishing paper) in continuous rolls for camshaft, crankshaft, printing roller and shaft superfinishing lines. Engineered for consistent cut rate and surface finish (Ra) over long production runs on automated microfinishing equipment — roll widths slit to match your machine.
| Abrasive | Aluminum oxide / silicon carbide / diamond |
| Micron grades | 9, 15, 20, 30, 40, 60 μm |
| Roll widths | Slit to machine spec (custom) |
| Formats | Continuous rolls |
| Typical applications | Camshaft & crankshaft finishing, rollers, shafts |
Polishing Tapes & Flocked Pile Films
Fine polishing tape and flocked pile polishing film for fiber optic connector endface cleaning and polish, MPO/MTP arrays and 3C electronics. Flocked pile structure carries slurry evenly for a haze-free final surface — paired with our diamond films as a complete connector polishing consumables set.
| Type | Fine polishing tape / flocked pile film / cleaning rollers |
| Micron grades | 0.5–9 μm (tape), pile for slurry polish |
| Backing | PSA or plain |
| Formats | Tapes, rolls, sheets |
| Typical applications | Fiber connector endface, MPO/MTP, 3C electronics |
All grades available with PSA (pressure-sensitive adhesive) or plain polyester backing. Custom widths, lengths, die-cut disc shapes and private-label converting on request.
