XYT™ Lapping Films – Technical Data Sheets

Comprehensive Overview of XYT Precision Polishing Films
(For Fiber Optics · Electronics · Metallography · Semiconductors · Precision Engineering)

1. Diamond Lapping Film Series (1–80 µm)

Abrasive: Diamond (Synthetic) | Backing: PET (3 mil / 5 mil) | Form: Sheet · Disc · Roll

Description:
XYT™ Diamond Lapping Films deliver superior cutting performance and durability for polishing hard materials such as ceramics, glass, tungsten carbide, and ferrules. The uniformly graded diamond abrasives ensure precise surface control, excellent edge retention, and consistent geometry throughout the polishing process.

Applications:

• Fiber optic ferrule end-face shaping

• Metallography sample preparation

• Flat lapping and superfinishing

• Ceramics, semiconductors, and hard alloy finishing

Micron Range: 0.1 µm – 80 µm
Compliance: RoHS / REACH Certified

2. Aluminium Oxide (Al₂O₃) Lapping Film Series (1–80 µm)

Abrasive: Aluminium Oxide | Backing: PET (3 mil) | Form: Sheet · Disc · Roll

Description:
Ideal for multimode connector and general precision finishing where diamond abrasives are not required. The Al₂O₃ film offers balanced cutting and surface smoothness. High repeatability and long life make it a cost-effective alternative to diamond films.

Applications:

• MM/SM connector polishing

• Metal and alloy surface finishing

• CD/DVD stamper polishing

• Micromotor shaft and precision part finishing

Micron Range: 1 µm – 80 µm
Compliance: RoHS / REACH Certified

3. Silicon Carbide (SiC) Lapping Film Series (1–30 µm)

Abrasive: Silicon Carbide | Backing: PET (non-flocked) | Form: Sheet · Disc · Roll

Description:
Engineered for third-stage fiber protrusion and geometry control of MPO/MTP ferrules. The non-flocked PET backing prevents particle shedding, keeping alignment holes and fibers clean and minimizing insertion loss.

Applications:

• MPO/MTP ferrule pre-polish or repair

• Ceramic ferrule end-face geometry correction

• Hard metal and composite finishing

Micron Range: 1 µm – 30 µm
Stable MT TMT Fiber Height: 1600 – 2100 nm (typ.)
Compliance: RoHS / REACH Certified

4. Silicon Dioxide (SiO₂) Lapping Film Series (0.02–3 µm)

Abrasive: Silicon Dioxide | Backing: PET | Form: Sheet · Disc · Roll

Description:
Ultra-fine polishing films for final finishing of fiber connectors and ferrules. Achieves superior surface smoothness and high return loss. Designed for use with DI water only to prevent chemical residues.

Applications:

• Final polish step for MT, TMT, and ceramic ferrules

• High-performance MPO/MTP connector finishing

• Precision glass or optical component polishing

Micron Range: 0.02 µm – 3 µm
Compliance: RoHS / REACH Certified

5. Cerium Oxide (CeO₂) Lapping Film Series (0.2-1 µm)

Abrasive: Cerium Oxide | Backing: PET | Form: Sheet · Disc

Description:
High-efficiency final polishing film designed for fiber optic end-face finishing. Provides long life, improved polish rate, and low defect count — outperforming NTT ADS equivalents in longevity and finish consistency.

Applications:

• Final step in SM/MM fiber optic connector polishing

• Mirror surface finishing on glass and ceramics

Micron Size: 0.2-1 µm
Compliance: RoHS / REACH Certified

6. Specialty & Custom Films

• Foam-Backed Films: For improved surface conformity

• Structured Abrasive Films: For consistent micro-removal

• Customized Rolls/Discs: 1"–16" diameters or OEM-labeled rolls
