What is abrasion?

Abrasion corresponds to the removal of a material surface by mechanically occurring friction.

The resistance of a material to abrasion is measured in a standardized way and specified as an abrasion index. The rubber is clamped onto a roller and rolled against emery paper at a constant contact pressure. The volume loss (material loss) is compared with a standard sample.

Abrasion resistance index = S / T – 100 (%),

where
S = volume loss of the standard sample
T = volume loss of the test vulcanizate.
