Abstract
This invention provides a tube having durability against harsh flexion, shrinkage, torsion, or the like and reduced slip resistance between tubes or upon contact with another member. Such tube is used for a product comprising a site at which a plurality of tubes are fixed at both ends and tied together with each other and/or in contact with another member, and the sites of fixation at the both ends are sites of motion at which reciprocal movement is repeated. Such tube is obtained via extrusion molding of a thermoplastic polyether ester elastomer and has a satin-finished outer surface. The invention also provides a method for preparing such tube.
