In addition to the very high wear and abrasion resis- tance, the excellent tear growth resistance and cold flexibility of the material at low temperatures should also be mentioned. TPU can be made for a large hardness range and from an ergonomic point of view it can also be used advantageously due to its good surface feel (Softline!). * + resistant, o conditionally resistant, – non-resistant Material Characteristics of Plastics Materials and Elastomers continued
