Abrasion comes in two flavours: sliding and impingement. The passing of an adjacent surface across the rubber surface is known as sliding. Sand grains striking the surface are an example of impingement, which is the wearing down of rubber. In actual service, sliding and impingement together cause the majority of the wear.

Localized friction forces that cause sliding can put a lot of energy into the rubber. When the rubber cannot endure these forces, abrasion and wear occur.

There are at least 25 laboratory abrasion test devices, which suggests that it is challenging to relate the results of this kind of test to service performance. The National Bureau of Standards Abrader, a slinging type abrader, is the most well-known testing apparatus in the rubber sector. The NBS Abrader operates at a steady speed with a fixed load and an established abrasive grit.

It does not provide information on a compound’s performance across a wide range of conditions or regarding cut resistance, chunking, or flat spots.
