The abrasion test procedure (ISO 4649 / DIN 53516) is fairly straightforward. By rubbing a test piece of rubber across the surface of an abrasive sheet mounted on a rotating drum, abrasion resistance is measured. It is expressed as a reduction in volume measured in cubic millimetres, such as 150 mm3.

The most crucial thing to remember when analyzing the abrasion test results is that higher numbers indicate a weaker resistance to abrasion due to a greater loss of surface rubber. The stronger the wear resistance, however, the lower the figure. A single belt with strong abrasion resistance can frequently outlast two or even three ‘budget’ belts of lesser grade.

Numerous applications call for materials that can withstand abrasive conditions and difficulties, particularly in industrial settings. Rubber that can withstand abrasion is the ideal substance. Make sure you are aware of how rubber abrasion resistance is evaluated, and choose a protective rubber that performs well under the harsh conditions of a rotating drum. This will assist you in selecting the best material forms to withstand the roughest situations.
