MPO/MTP Polishing Pad

MPO/MTP Polishing Pad is a black polyurethane (PU) microporous polishing medium intended for precision polishing of MPO/MTP fiber-optic connector ferrules with polishing slurry. GRISH describes softness, flexibility, internal liquid-retaining structures, scratch reduction and long service life; these remain unverified supplier claims. Manufacturer source specifications: Material: Polyurethane (PU); Abrasive: N (unexplained literal source entry, not confirmed as an abrasive mineral); Color: Black; Thickness: 0.70–1.10 mm; Shaw/Shore Hardness (A): 70–90 (manufacturer spells Shaw); Density: 0.500–0.700 g/cm³; Standard Disc: Ø127 mm with PSA; Standard Sheet: 140 × 140 mm with PSA. Source also separately lists 'Round: Ø70 mm, Ø110 mm (4.3 inch), Ø127 mm (5 inch), Ø203 mm (8 inch)' but does not clearly state which of those have PSA backing or correspond to a commercial SKU, so availability by form remains unverified. GRISH application instructions: attach pad PSA to glass support without air gaps, use AO and CO slurry during polishing and clean with water after processing. SC16 and SC9 in illustrations are separate lapping-film stages, not pad models. Vendor text's diamond-film dry-polishing paragraph is not evidence of the pad's dry-polishing capability. Not HANS-certified.
