Greater Abrasion Resistance And Crushing Strength
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 15If high mechanical strength is required in an abrasive

Cold Crushing Strength Restar
The Cold Crushing Strength CCS represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. The higher the CCS of a material is the greater should be the resistance to abrasion. Refractories with high CCS are also expected to have higher.
