Thermoplastic fluororesin tube

Abstract

A method for producing a thermoplastic fluororesin tube, the thermoplastic fluroresin tube having tearability in a longitudinal direction, wherein a thermal expansion coefficient in the longitudinal direction upon heating in a gaseous phase at a temperature of 100° C. for 5 minutes is 0% or more, the method including the steps of: subjecting a thermoplastic fluororesin to melt extrusion molding to obtain a raw tube of the thermoplastic fluororesin tube; and expanding an inner diameter of the raw tube while heating the raw tube to a temperature of from 110-135° C.
