Maemo a tloaelehileng a ts'ebeliso ea litiiso tsa rabara tsa perfluoroether FFKM a kenyelletsa:

• Indasteri ea semiconductor(ho bola ha plasma, ho bola ha khase, ho bola ha asiti, ho bola ha mocheso o phahameng, ditlhoko tsa bohloeki bo phahameng bakeng sa ditiiso tsa rabara)
• Indasteri ea meriana(ho bola ha asiti ya manyolo, ho bola ha motheo wa manyolo, ho bola ha solvent ya manyolo, ho bola ha mocheso o phahameng)
• Indasteri ea lik'hemik'hale(ho bola ho matla ha asiti, ho bola ho matla ha motheo, ho bola ha khase, ho bola ho solvent ya organic, ho bola ho phahameng ha mocheso)
• Indasteri ea peterole(ho bola ha oli e ngata, ho bola ha hydrogen sulfide, ho bola ha sulfide e ngata, ho bola ha dikarolo tsa tlhaho, ho bola ha mocheso o phahameng)
• Indasteri ea likoloi(ho bola ha oli mochesong o phahameng, ho bola ha mocheso o phahameng)
• Indasteri ea electroplating ea laser(mafome a mocheso o phahameng, bohloeki bo phahameng ba perfluororubber ha e kgone ho baka di-ion tsa tshepe)
• Indasteri ea betri(ho bola ha asiti-base, ho bola ha mahareng ho matla, ho bola ha mahareng ho matla ho oksidang, ho bola ha mocheso o phahameng)
