Ukusetshenziswa

I-Perfluoropolyethers (PFPE) yaqala ukufundwa ngawo-1960.Kuwuhlobo lwama-perfluoropolyethers akhethekile.Isilinganiso sesisindo samangqamuzana sisuka ku-500 siye ku-15000. Kunezici ezintathu zencwadi yamakhemikhali engu-C, F, O kuphela ku-molecule.Inezici zokumelana nokushisa, ukumelana ne-oxidation, ukumelana nemisebe, ukumelana nokugqwala, ukungashi, njll. Sekungamashumi eminyaka isetshenziswa njengesithambiso esithembeke ngokwedlulele kwezempi, i-aerospace, imboni yenuzi nakwezinye izinkambu ezisezingeni eliphezulu.Namuhla, i-perfluoropolyether isetshenziswa kabanzi embonini yamakhemikhali, i-electronics, izinto zikagesi, imishini, imboni yenuzi, i-aerospace.
