Dharka dahaarka leh ee PTFE , oo sidoo kale loo yaqaanno maro dahaarka leh ee Teflon ama maro dahaarka leh ee PTFE, ayaa ugu horreyn ah walxo dahaarka ah. Isku-dhafkan cajiibka ah wuxuu isku daraa xoogga fiberglass iyo sifooyinka gaarka ah ee PTFE (Polytetrafluoroethylene). Dahaarka PTFE wuxuu abuuraa dusha aan shaqaynayn, taas oo ka dhigaysa dharka mid aad u fiican oo koronto ah. Gurigan dahaarka ah waa mid ka mid ah sababaha ugu muhiimsan ee dharka dahaarka leh ee PTFE si weyn loogu isticmaalo warshado kala duwan, laga bilaabo elektiroonigga ilaa hawada sare. Si kastaba ha ahaatee, waxaa muhiim ah in la ogaado in iyada oo daboolka PTFE laftiisa uusan ahayn mid waxtar leh, substrate fiberglass-ka hoose wuxuu yeelan karaa heerar kororsi ah oo ku xiran halabuurka. Codsiyada wax ku oolka ah intooda badan, dharka dahaarka leh ee PTFE waxaa loo tixgeliyaa insulator, oo siinaya iska caabin heer sare ah socodka korantada hadda.
