3M Imperial® Diamond Lapping Film

Imperial® Diamond Lapping Film offers a repeatable,
precision finish on extremely hard materials. It combines
micron-graded diamond particles, a resin bonding system
and a highly uniform polyester film.

Applications: carbides, ceramics, high-hardness metals,
rocks and minerals, fiber optic connectors, magnetic heads,
metallurgical testing, and other lapping and polishing

Converted forms: sheets, discs, rolls.

Available Backings: 0.5, 1, 1.5, 2, and 3 mil backings. Sheets and discs available with self-adhesive backing.

Available Grades: 0.1, .05, 1, 105, 3, 6, 9, 15, 20, 30, 45, and 60 micron. (Not all grades are available in all products.)

Other Information:

Imperial® Diamond Lapping Film Type B - Diamond particles are contained in ceramic beads which makes this product more aggressive than the standard product. Grade for grade a Type B product will yield more cut, longer life, and a coarser finish. Recommended for extremely hard materials and larger parts.

Imperial® Diamond Lapping Film Type P - The resin bond is harder that the standard product. Used primarily in roll superfinishing applications and flat lapping operations.

Imperial® Diamond Lapping Film Type H - Provides a higher cut rate and longer life than the standard IDLF. A thicker diamond coating and harder resin prevent "score through" and increase cut rate, making this a long lasting, clean polishing, premium diamond abrasive. Used primarily for fiber optics and
Connector polishing.
