Abstract
A flexible tube for an endoscope has a flexible tube substrate that is flexible and tubular and a resin layer (A) covering the flexible tube substrate. The resin layer (A) includes a thermoplastic resin (a) including at least one of a polyamide resin, a polyurethane resin, a polyester resin, a polystyrene resin, or an acrylic resin and having a tensile strength at 10% elongation of 10 MPa or more and a hindered amine compound (b) having a molecular weight of 500 or more. Also provided are an endoscopic medical device including the flexible tube for an endoscope and a resin composition suitable for forming the resin layer of the flexible tube for an endoscope.
