As design materials for ski boots,transparent grades of Desmopan~R thermoplastic polyurethane(TPU)have set new trends and are being used by more and more manufacturers.Now,with the introduction of Desmopan~R DP 9650DU,DP 9659DU,DP 9662DU and DP 9665DU,Bayer MaterialScience AG has succeeded in developing a new generation of these aromatic ether TPUs that offers even better performance."The strength of the new grades lies in the significantly improved low-temperature flexibility and low-temperature impact strength.These features mean that ski boots can be made stronger and manufactured in thinner wall thicknesses,thus allowing greater design freedom.This is especially true for areas where two different TPU materials overlap,"says Luigi Cermesoni,head of the Sports&Leisure TPU segment at Bayer MaterialScience.The new materials are already being used by well-known manufacturers such as Tecnica(in its Diablo model)and Nordica(in its Speedrriachine model).
