Abstract: A thin-walled polyether block amide (PEBA) tube 40 with a thickness of no greater than 100 micrometres. The tubes may be formed by extruding a PEBA copolymer. The tube may also comprise a permeable support 10. This support may be made of a metal or polymer and may be a braided sleeve. The support may be configured either inside or outside the PEBA tube. The support may be porous with the PEBA having been melted into the pores of the support. The support may have an open area of 60 % or more. In embodiments, the tube wall thickness may be no greater than 75 micrometres. The tube may comprise additives to improve mechanical strength, desiccants to increase moisture vapour transfer rate and biocides. The tubes may form part of a pervaporation module.
