There are generally two forms of abrasion. Sliding and impingement are these. When the surrounding surface slides across the rubber surface, sliding abrasion occurs. Impingement abrasion, on the other hand, is characterized by sand particles that strike the surface as the rubber wears away. In actual service, the two types of abrasion combine to cause the majority of the wear.

When sliding on rubber, localized or constrained friction forces can cause significant energy damage. Abrasion and wear occur when the rubber is unable to endure such forces.

Particle impingement occurs in a variety of applications, including chutes, sandblast hoses, and rebound plates. Elastomers are easily yieldable, which allows them to disperse the tension caused by particle impingement. There will be a 90-degree impingement angle during a sandblast test. Compared to steel or cast iron, rubber is resilient and supple and has greater abrasion resistance.
