# UltraPol, PSA, 2.875 in (QTY/EA) 20

UltraPol is a hard, woven, non-aggressive silk cloth. It is used to maintain excellent flatness during intermediate polishing especially for mixed materials. The non-aggressive material removal rate minimizes surface damage. Typical applications include but are not limited to minerals, coals, inclusion retention in steels and refractory metals.
