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

• Indasteri ea semiconductor(corrosion ea plasma, kutu ea khase, kutu ea acid-base, kutu e phahameng ea mocheso, litlhoko tse phahameng tsa bohloeki bakeng sa litiiso tsa rabara)
• Indasteri ea meriana(organic acid corrosion, organic base corrosion, organic solvent corrosion, corrosion e phahameng ea mocheso)
• Indasteri ea lik'hemik'hale(corrosion e matla ea acid, corrosion e matla ea base, corrosion ea khase, corrosion ea organic solvent, corrosion e phahameng ea mocheso)
• Indasteri ea peterole(ho bola ha oli e boima, hydrogen sulfide corrosion, corrosion e phahameng ea sulfide, corrosion ea motsoako oa lintho tse phelang, kutu e phahameng ea mocheso)
• Indasteri ea likoloi(mocheso o phahameng oa oli, ho bola ha mocheso o phahameng)
• Indasteri ea laser electroplating(ho bola ha mocheso o phahameng, bohloeki bo phahameng ba perfluororubber ha bo khone ho fokotsa li-ion tsa tšepe)
• Indasteri ea betri(corrosion ea acid-base, corrosion e matla e mahareng, kutu e matla ea oxidizing, corrosion e phahameng ea mocheso)

• Indasteri ea matla a nyutlelie le matla a mocheso(thempereichara e phahameng ea mouoane, corrosion ea metsi a mocheso o phahameng haholo, corrosion ea mahlaseli a nyutlelie)
