Abrasion Resistance - an overview ScienceDirect Topics

Abrasion resistance is a complex function of tear strength, coefficient of friction, resilience, heat dissipation, and other properties, and comparative values depend on the type of test. In general, COPEs are superior in abrasion resistance to many flexible materials including polyvinyl chloride (PVC) and some rigid plastics [15].If high mechanical strength is required in an abrasive ...
