The Language of Rubber – Part 5 (Abrasion Resistance) By John Woon (Senior Latex Consultant)

Abrasion resistance is defined as the resistance of the rubber product to wearing when the surface is being rubbed with an abrasive surface of another object, under a given load and speed of abrasion.

The amount of the material being abraded away is compared with that of a standard specimen.

Although the standard test does not always correlate well to actual service performance, it is a good quality control test for products exposed to abrasion during service life such as industrial gloves, tire treads, conveyor belts, heels and soles, floor coverings,and sandblast host etc.

Abrasion resistance could sometimes be affected by a combination of other properties such as resilience, stiffness, thermal stability, cut and tear resistance.
One should be cautioned that excessive blooming of oil and/or wax or an under cured product might give a misleadingly good abrasion resistance during the test due to the abrasive being clogged and lubricated by the abraded material from the rubber surface.
