Abstract

PURPOSE: To improve heat resistance and elastic repulsion and to obtain a flexible tube with excellent heat resistance and inserting characteristics by forming a skin for a flexible tube of an endoscope by mixing a thermoplastic polyester elastomer and a thermoplastic polyurethane elastomer.
CONSTITUTION: A flexible tube 1 is constituted of a braid 3 prepd. by knitting with a fine wire of a metal with which a flex 2 prepd. by spirally wounding an elastic belt-like sheet is covered and a skin 4 with which the whole periphery of this outer surface is covered. A polyester elastomer consists of a polyether- ester copolymer wherein PBT is a hard segment and PTMEGT is a soft segment and a polyester-ether copolymer wherein PBT is a hard segment and polycaprolactone is a soft segment. In a polyurethane elastomer, a polymer chain consisting of a diisocyanate and a short chain glycol is a hard segment and a polyester polymer chain consisting of a diisocyanate and a long chain polyol is a soft segment. This polymer is prepd. by copolymerizing both segments.
