摘要： The present invention relates to a PVC-free tube (100) for medical purposes comprising three layers (101, 102, 103) arranged one above another, wherein each of these layers contains a polyolefin, and wherein the inner layer (102) also contains at least 60% of a thermoplastic elastomer. The present invention further relates to a tube system comprising several tubes according to the invention, which are connected via connectors. The tube according to the invention makes it possible for the conveyance rate loss, for example in an extracorporeal blood circulation, to be less than 15%, preferably less than 10%.

摘要： A PVC-free multilayer tube, preferably for medical purposes, with more dependable peelability, comprises at least three layers, of which a base layer comprising a first plastics material has been bonded to at least one connection layer comprising a second plastics material by means of at least one buffer layer arranged between the base layer and the at least one connection layer, the buffer layer comprising a third plastics material, wherein the multilayer tube can be used to mold a coil or a loop with a diameter of down to 50 mm without undesirable kinking. Each of the first and second plastics materials is comprised of at least 25% by weight, based on the total weight of the base layer and the connection layer, respectively, of polyolefins, while the third plastics material has a proportion, based on the total weight of the buffer layer, of more than 75% by weight of a thermoplastic elastomer which is not a polyolefin.
