| PU | Very resistant to sliding wear under humid conditions and has low friction. |
| T60 | Extremely resistant to the wear and tear of impacting, large sized, abrasive rocks. |
TR60 | Used for less severe crushing and cutting abrasion. |
| T40 | Used for sliding abrasion of small particles. It is the high rate of elongation that makes T40 particularly well suited as protection against small, sharp and hard particles eroding the surface. |
