Factors affecting the quality of polishing pads

- Jun 13, 2017 -

① Hardness-the hardness of the polishing pad determines the ability to maintain the precision of the surface.

② Compression ratio-compression ratio reaction polishing pad of deformation resistance;

③ The quantity of self-restraint-polishing pad is the quality of the polishing Pad storage unit volume.

④ Roughness-surface roughness is the surface of the polishing pad, concave and convex degree;

⑤ Density-density is the degree of densification of the polishing pad material;
