Amakhemikhali abalulekile we-PTFE, izinga lokushisa, umswakama, nokumelana nogesi kuyenza ibe into efanelekile noma nini lapho imikhiqizo, amathuluzi, nezingxenye kudingeka ziqine futhi zithembeke ngisho nasezinhlelweni ezinzima kakhulu.Phezu kwalokhu, i-PTFE intambo enombala ogqamile inokuqina okuyingqayizivele kwezinga lokushisa eliphansi kanye nokumelana nomlilo okwenza kube ukukhetha okuhle kohlu olukhula njalo lwemikhiqizo, izakhi, kanye nezinhlelo zokusebenza.
Amakhebuli e-PVC akhiqizwa ngenani eliphansi kakhulu ngenxa yokuthi akudingekile ukuthi ahlangabezane nesilinganiso sokushisa esiphezulu esenziwa yizintambo ze-PTFE.I-PVC imele i-Polyvinyl Chloride okuyinhlanganisela eyakhelwe ukusetshenziswa ku-electronics nezinye izinhlelo zokusebenza zasendlini.
Izintambo zikagesi ze-PVC zihlangabezana nezinga lokushisa elingu-105°C kuma-volts angu-300 noma angu-600.Akhiwe ngemicu yethusi eguquguqukayo kanye nokufakwa kwe-PVC kumakhondaktha angaphakathi.Ngezinye izikhathi ziza nesihlangu se-aluminium jikelele se-foil kanye nocingo lokudonsa ithusi.
Manje njengoba usuwazi ukwakhiwa kwekhebula le-PVC cishe uzoqonda ukuthi kungani ikhebula le-PTFE libiza kakhulu.Inhlanganisela ye-PTFE isetshenziselwa ukukhiqiza into yokushisa engu-200°C ukumboza abaqhubi bethusi.Unjiniyela ohilelekile ekudaleni ikhebula elingu-200°C uhileleke kakhulu kunenqubo yokudala ikhebula elingu-105°C.
Amakhondaktha angaphakathi ezintambo ze-PTFE aphinde abe nokufakwa kwe-PTFE okubizwa ngokuthi Uhlobo E noma i-M16878/4 nakho okuhlangabezana nezinga lokushisa eliphezulu elingu-200°C.Akhiwe ngemicu yethusi ecwebe ngesiliva okusho ukuthi izindleko zethusi eziphezulu nesiliva eliphakeme kufanele zifakwe emananini ezintambo ze-PTFE.
Isizathu sokugcina samanani aphezulu ezintanjeni ze-PTFE iqiniso lokuthi ukuzamazama komhlaba e-Japan kuthinte umkhiqizi wonke we-PTFE ikhompawundi ebithumela inhlanganisela kubakhiqizi bezintambo be-PTFE.Lokho kudale ukushoda okukhulu kwezintambo ze-PTFE emakethe okuqhubekisele phambili namanani entengo.
Ngeke ngithande ukusho ukuthi ikhebula le-PVC kulula ukulenza, kodwa uma uyiqhathanisa nekhebula le-PTFE kubonakala sengathi uhamba ngezinyawo epaki.Zombili izintambo zinemvume ye-UL ne-CSA kanye nokuhambisana ne-RoHS, kodwa izintambo ze-PTFE zingasetshenziswa ngaphandle, emazingeni okushisa aphakeme futhi zimelana namanzi, amagesi, uwoyela, izinyibilikisi nokunye okuningi.
