Abstract

PURPOSE:To provide the titled resin tube having a high content ratio of filler and no defect by a method wherein a sheet of polyethylene tetrafluoride resin containing filler and assistant is formed in the form of a tube of equal thickness and then stretched and fixed. CONSTITUTION:A sheet of polyethylene tetrafluoride resin which contains filler (titanium oxide, carbon black, etc.) and assistant (such as naphtha)by 15-70wt% is wound about core material 2 provided with thermoshrinkable tube 3 and reinforcing material (such as polyethylene tetrafluoride resin) 4 is wound on it to provide tube body 5 and thereafter this tube is pressed and revolved between flat plates to obtain a tube body 6 of equal thickness. Then, the thermoshrinkable tube 3 is shrunk by heating and removed along with the core material 2. Besides, the tube body 6 is preheated at 327 deg.C or more for about 20min to obtain a porous polyethylene tetra fluoride tube containing filler.
