Juriya na Radiation Polytetrafluoroethylene yana da ƙarancin juriya na radiation (104 rad), kuma yana raguwa bayan an fallasa shi zuwa radiation mai ƙarfi, kuma kayan lantarki da na injiniya na polymer sun ragu sosai. Aikace-aikacen Polytetrafluoroethylene za a iya kafa ta hanyar matsawa ko sarrafa extrusion; Hakanan za’a iya sanya shi ya zama tarwatsa ruwa don sutura, tsoma ko yin zaruruwa. PTFE ne yadu amfani da high da low zafin jiki resistant, lalata resistant kayan, insulating kayan, anti-stick coatings, da dai sauransu a makaman nukiliya makamashi, Aerospace, Electronics, lantarki, sinadaran, inji, kida, mita, yi, Textiles, abinci da sauran. masana’antu.

Juriya na tsufa na yanayi: juriya na radiation da ƙarancin ƙarfi: fallasa yanayi na dogon lokaci, farfajiya da aiki ba su canzawa.

Non-combustibility: Ingancin iyakar iskar oxygen yana ƙasa da 90.

Acid da juriya na alkali: mara narkewa a cikin acid mai ƙarfi, alkalis mai ƙarfi da kaushi.

Juriya na oxyidation: tsayayya da lalata ta hanyar ƙarfi oxidants.
