Mitengo ya emulsion ya PTFE imakhudzidwa ndi zinthu zonse zamafakitale. Mtengo wokwera (migodi ya fluorite, ma R22 refrigerant quotas) amakhazikitsa mtengo woyambira. Kufuna kwapansi kwa mabatire a lithiamu ndizomwe zimayendetsa kukula. Zinthu zomwe zimaperekedwa (mitengo yamafakitale, kukonza mbewu) ndi mtundu wazinthu (zolimba, kukula kwa tinthu, kalasi yoyera) zimapanga magawo amitengo. Malamulo azachilengedwe (PFOA/PFAS zoletsa) amakweza mtengo wotsatira. Logistics (zoyendera zozizira) zimawonjezera ndalama zambiri. Mayendedwe amitengo amatsata mfundo yayikulu: mtengo wa fluorite/hydrofluoric acid = pansi; kufunikira kwa batri yatsopano yamphamvu = mayendedwe; mitengo ya ntchito ndi ndondomeko = zoyambitsa kusakhazikika kwakanthawi kochepa.
