Abstract
A polytetrafluoroethylene tube is provided and has a thickness of 0.1 mm or less, a tensile elongation at break of 350% or more, and a melting energy of 0.6 J/g or more which is calculated from an endothermic peak at 370° C.±5° C. in a procedure of increasing a temperature in differential scanning calorimetry (DSC).
Claims15

(canceled)
A polytetrafluoroethylene tube having a thickness of 0.1 mm or less, tensile strength at a tube displacement amount of 10 mm when being measured at a distance of 50 mm between chucks is 50 to 93.0 N/mm2.
(canceled)
A polytetrafluoroethylene tube having a thickness of 5% or less of an outer diameter, a tensile strength at a tube displacement amount of 20 mm when being measured at a distance of 50 mm between chucks is 70 N/mm2 or more.
