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

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

Abrasive: Aluminium Oxide | Backing: PET (3 mil/5 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

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
