Cloth is less sensitive to tearing, withstands greater torsional forces than paper, and has a higher tensile strength. Paper is cheaper and performs the same function. However, if it gets snagged on the edge, it has a cutting effect and tears. Cloth does not have this issue and thus better withstands pressures.

Soft cloths are thinner and better adapt to uneven or rounded surfaces, while hard cloths are more robust and are therefore more intended for rough sanding.

No, each manufacturer has its own color codings, and the materials and technologies may differ despite the same color.
