Polyurethane components possess the outstanding engineering properties for industrial application. The inherent strength and ingrained superiority of polyurethane make them most appropriate for demanding industrial (mechanical, chemical, thermal & electrical) applications. Its high co-efficient of friction leads to versatile applications in frictional drives. Its good electrical & thermal properties, resistance to chemical media and wide working temperature range gives the additional characteristics to its application. Its excellent abrasion resistance together with very high impact & tensile strength and tough tear strength makes polyurethane versatile for engineering application. Depending upon the application, polyurethane can be formulated to exhibit low or high resilience and wide range of hardness. Polyurethane can be extruded, moulded or casted to the desired shape of item depending upon the shape, size and applications.
