Pressure-sensitive adhesives (PSA) backing: adhesive backing is available on all types of pads. PSA backing ranges from high-holding to low tack/easy release.

Grooving :grooves improve pad performance by reducing excess slurry from the pads surfaces. More Superhard pad in offered in a variety of groove configurations . The depth of a groove is usually half of the pad thickness, only pad with thickness of more than 2 mm can be grooved . Groove width is usually 2 mm, and the island size is usually 16*16 mm.
