Lapping film
Lapping film in the telecommunications market is a precision coated abrasive consumable mainly used for processing and polishing optical fiber connectors. A Lapping film is typically a polyester base sheet, coated with precisely graded minerals such as diamond, aluminium oxide, silicon carbide, silicon oxide, cerium oxide. A Lapping film is designed to provide a uniform, consistent finish of optical fiber connectors end tips to ensure efficient light/signal transmission. They are available in 0.01-45 μm grades, with or without pressure-sensitive adhesive (PSA) backing.
Advantages
Lapping film is a kind of ultra fine coated abrasive which is quite different from regular ones.
- The size of material coated on the lapping film is ranging from 0.01-45 um;
- The base film is polyethylene terephthalate (PET), not paper or fabric.
Applications
Lapping and polishing Fiber connector; coated minerals: diamond, aluminum oxide, silicon oxide, etc. Equipment: Fiber Optic machine
Main manufactures
There are many global manufacturers of lapping film. The best are made in the United States (3M, and Nanolap Technologies).
