Abstract
The wear resistance of several thermoplastic polyurethanes (TPUs) having different chemical nature and micronscale
arrangement of the hard and soft segments has been investigated by means of erosion and abrasion tests. The goal was
correlating the erosion performances of the materials to their macroscopic mechanical properties. Unlike conventional tests,
such as hardness and tensile measurements, viscoelastic analysis proved to be a valuable tool to study the erosion resistance
of TPUs. In particular, a strict correlation was found between the erosion rate and the high-frequency (~10^7 Hz) loss modulus.
The latter reflects the actual ability of TPU to dissipate the impact energy of the erodent particles
