Abstract
A polymer material, in particular for a medical instrument such as a balloon catheter, is provided. The polymer material comprising a combination at least of a first constituent comprising a partly crystalline polymer and a second constituent for increasing the flexibility of the material, wherein the polymer material is in the form of a polymer alloy, and wherein the first constituent is formed of a polyamide or a polyether block amide and the second constituent is formed at least partly by a thermoplastic elastomer based on polystyrene (TPE-S). A process for producing the polymer material and a medical device incorporating the polymer material are also provided.
