FKM Copolymer vs FKM Terpolymer
Copolymer: 66% ea litaba tsa fluorine, kopo e akaretsang, ho hanyetsa oli, mafura, mocheso, lik'hemik'hale. Tšebeliso e tloaelehileng ke li-rings, litiiso tsa oli, li-packers, li-gaskets, joalo-joalo.
Terpolymer: litaba tsa fluorine tse phahameng ho feta copolymer 68% ea fluorine. Ho hanyetsa hamolemo oli, mafura, mocheso, lik'hemik'hale, tse sebelisoang tikolohong e thata eo copolymer e ke keng ea khotsofatsa litlhoko.
Bisphenol e phekolehang FPM vs Peroxide e phekolehang FPM
Bisphenol e phekolehang FPM e na le sete e tlase ea compression, tlhahiso e sebelisetsoang li-o-rings, litiiso tsa shaft, litiiso tsa piston. Theko e ntle.
Peroxide e phekolehang FPM e na le khanyetso e ntle holi-solvents tsa polar, mouoane, li-acids, lik'hemik'hale.Theko e phahame haholo. Hangata e sebelisoa bakeng sa lisebelisoa tse aparoang, li-hoses tsa extrusion fuel.
