Abstract | The present invention relates to a tube having one or more layers made of polytetrafluoroethylene, and addresses the problem of providing a tube having controlled flexibility while maintaining high mechanical strength. The problem can be suitably solved by a tube having one or more layers formed by winding a PTFE film in a helical shape. The tube has an endothermic peak in the range of 380°C ± 10°C when heated during DSC measurement. In one or more of the layers, the number of turns per 10 mm length in the longitudinal direction is not uniform.
La présente invention concerne un tube ayant une ou plusieurs couches en polytétrafluoroéthylène, et aborde le problème de fourniture d'un tube présentant une souplesse contrôlée tout en conservant une résistance mécanique élevée. Le problème peut être résolu de manière appropriée par un tube ayant une ou plusieurs couches formées par enroulement d'un film de PTFE sous forme hélicoïdale. Le tube a un pic endothermique dans la plage de 380 °C ± 10 °C lorsqu'il est chauffé pendant la mesure DSC. Dans une ou plusieurs des couches, le nombre de tours sur une longueur de 10 mm dans la direction longitudinale n'est pas uniforme.
本発明は、ポリテトラフルオロエチレンで形成される層を少なくとも1つ以上有するチューブに関し、高い機械的強度を保ちながら、柔軟性が調節されたチューブを提供することを課題とする。その課題は、PTFEフィルムを螺旋状に巻回して形成される層を少なくとも1つ以上有するチューブであって、該チューブのDSCの昇温過程において、380℃±10℃の範囲に吸熱ピークを有し、該層の少なくとも1つ以上の層において、長手方向における長さ10mm当りの巻回数が一定ではないチューブによって、好適に解決できる。 |
