Abstract: Tubing for carrying aqueous, aqueous-alcoholic or purely alcoholic liquids, in which at least the inner part of the tube wall consists of a molding material containing (I) 40-80 parts by weight (pts. wt.) polyamide and (II) 60-20 pts. wt. elastic polymer with a main chain consisting essentially of carbon atoms only. Independent claims are also included for (a) molding material as above (I + II = 100 pts. wt.) containing not more than 2 wt% extractables, as measured by extraction of the granulated material with hot 100% ethanol under reflux; (b) a process for the production of tubes by extrusion or coextrusion of this molding material.
