XYT™ Lapping Films – Technical Data Sheets

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

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

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

Description:
Engineered for Fiber Optics · Electronics · Metallography · Semiconductors · Precision Engineering , 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

6. Specialty & Custom Films

Foam-Backed Films: For improved surface conformity
Structured Abrasive Films: For consistent micro-removal
Customized Rolls/Discs: 3"–16" diameters or OEM-labeled rolls
