Mohs hardnessRough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised by German mineralogist Friedrich Mohs in 1812. Minerals are ranked in comparison with the Mohs scale, which is made up of 10 minerals that have been given arbitrary hardness values on a scale from 1 (least hard, or talc) to 10 (hardest, or diamond).

This is said to be demonstrated by MagShield's Mohs hardness of 2. Assigned: Honeywell International Key statement: A polymeric sheet having excellent cut-resistance contains: (A) a polymeric material, and (B) a hard filler, the hard filler having a Mohs hardness value of at least about 3. Talc also has the lowest Mohs hardness on the mineral hardness scale and is therefore relatively non-abrasive. |
