Consuetudinem

Perfluoropolyethers (PFPE) primum annis 1960 studuit.Est genus speciale perfluoropolyethers.Mediocris ejus pondus hypotheticum ab 500 ad 15000 vagatur. Solus C, F, O tria elementa libri chemici in moleculo sunt.Notas habet resistentiae caloris, resistentiae oxidationis, resistentiae radiorum, resistentiae corrosionis, incombustibilitatis, etc. Usus est ut certissimus ducatus in re militari, aerospace, nuclei industriae et alia aciei agrorum decenniis.Hodie perfluoropolyether late in industria chemicis, electronicis, adminiculis electrica, machinationibus, industria nuclei, aerospace adhibetur.
