Polishing Pad

GRISH Polishing Pad is a microporous polishing pad intended for use with polishing liquid on wafers, ceramics and glass requiring high flatness. The manufacturer describes a microcellular polishing surface, chemical resistance, wear resistance and polishing stability. GRISH claims scratch-free non-mirror results and independent comparative testing; these are unverified external manufacturer claims and not HANS-certified performance. Source specification table is structurally shifted. Raw value row, in source order: 1.4±0.1 mm | 60±2 | 0.37 mm | 9% | 0.4±0.05 | Φ920±2 mm; raw table headers: 'Thickness | Hardness | Hole depth | Compression | Velvt | Size' with extra shifted header 'percentage | length'. Thickness appears to be 1.4±0.1 mm and size Φ920±2 mm, but mapping of hardness, hole depth, compression and 'Velvt' needs visual source confirmation. Do not treat unresolved values as finalized material properties or SKU options. The supplier's term 'diamond polishing pads' does not provide a confirmed abrasive concentration or grit grade.
