I-PTFE Teflon Tubing yenziwe ngenhlaka ye-polytetrafluoroethylene ephakeme ngokusebenzisa inqubo ekhethekile yokukhipha kanye ne-sintering. Umkhiqizo ungowokuvikela ugesi kakhulu, awubambezeli ilangabi kakhulu, uyazithambisa futhi umelana kakhulu nezinga lokushisa eliphakeme kakhulu (260°C), izinto ezisebenza ngamakhemikhali kanye nawo wonke uwoyela namanye amakhemikhali. Ithola ukusetshenziswa okubanzi ezimakethe zezimoto, zempi kanye nezimakethe ze-aerospace.
