Products / Lapping / Polishing / Lapping Film


Lapping film is ideal for applications in which edge retention is critical. Particularly with cross-sections of dissimilar hardness materials and so is often used in the fine grinding of photonics and electronics components. Our lapping film comprises a flat, high quality 3mil (76 micron) thickness polyester film coated with a finely graded abrasive in a choice of alumina, silicon carbide, cerium oxide or diamond. There is a choice of plain or PSA backed films in 2", 3",4", 5" 8" 10" and 12" diameters and in various size rectangular sheets all in a wide range of abrasive sizes as given in this table.
