Polyurethane Abrasion Resistance
The outstanding abrasion resistance of cast urethane elastomers has benefited hundreds of applications where severe wear presents a serious problem such as ore mining and sand and gravel processing. Field applications have proven open cast polyurethanes provide a definite wear advantage due it its superior abrasion-resistant properties. In working service, molded polyurethane has outworn rubbers and plastics, as well as steel and even ceramics. often by a factor of 10 to 1. The table below provides a comparison of abrasion resistant properties of open cast polyurethane with rubber and plastics.
