  • Application‑Optimized Materials: Full range of pad types for all sample preparation stages, from coarse material removal to final mirror finishing.
  • Consistent & Durable: High-quality fabric ensures uniform polishing and extended service life, lowering replacement frequency.
  • International Standard Compliance: Supports sample preparation in line with global standards including ASTM E3 and ISO 17781.

Material Selection Guide

Choosing the right pad material is critical for optimal surface finish and sample integrity. Select based on your sample material and preparation stage:
Pad Material
Pile Type
Ideal Applications
Silk Velvet
Long Pile
Final/fine polishing of hard materials (steels, high‑precision alloys) and soft non‑ferrous metals (aluminum, copper, magnesium).
Premium Silk Velvet
Medium–Short Pile
Versatile, durable polishing for steels, electronic circuit boards, and soft metals (copper, aluminum).
Canvas
No Pile
Initial coarse polishing; removes significant surface deformation from steel samples.
Silk Cloth
No Pile
Polishing of materials containing graphite or fragile inclusions (prevents pull‑out).
Nylon
No Pile
Coarse polishing of steels and other ferrous alloys (synthetic fiber construction).
Woolen Cloth
Short Pile
General polishing of steel materials (thickened navy wool).
Synthetic Polymer Pad (Synthetic Leather)
Compatible with diamond, alumina (Al₂O₃), and colloidal silica suspensions. Ideal for final fine polishing of very soft materials (titanium, copper, silver) and mechanochemical polishing (CMP).
