Kev piav qhia:
O Lub Nplhaib yog cov qauv siv tshuab tsis zoo rau kev foob, vim tias nws tus nqi qis, yooj yim los ua, khoom siv tau zoo ua haujlwm.
Cov roj hmab FFKM yog hais txog terpolymer ntawm perfluoro (methyl yas) tetrafluoroethylene, thiab perfluoroolefin. Kuj tseem hu ua FFPM.
Nws muaj cua sov thiab tshuaj lom neeg ruaj khov ntawm elasticity thiab polytetrafluoroethylene. Lub sijhawm ua haujlwm kub ntev -42 ~ 327 celsius degrees, lub sijhawm ua haujlwm ntev txog 343 celsius degrees, tseem muaj qee yam plasticity hauv qab embrittlement kub, qhov nyuaj tab sis tsis nkig, tuaj yeem khoov tau. Nws ruaj khov rau txhua yam tshuaj tsuas yog hauv cov kuab tshuaj fluorine.
