I-fluoroelastomer ingahlukaniswa ngezindlela ezilandelayo.
A. Uhlelo lokwelapha
B. Ama-Monomers
C. Izicelo
Ngohlelo lokwelapha, kunezindlela ezimbili ezijwayelekile: I-Bisphenol iyelaphekafkmkanye neperoxide iyelapheka fkm. I-Bishpenol yelapheka i-fkm ivamise ukuphatha izici zesethi yokucindezela ephansi, esetshenziselwa ukubumba izingxenye zokuvala ezifana nama-orings, ama-gaskets, izindandatho ezingajwayelekile, amaphrofayili. Futhi i-Peroxide yelapheka i-fkm inokumelana namakhemikhali okungcono kanye nezakhiwo zemishini. Inokumelana okukhulu nomusi. Ingasetshenziswa ezintweni ezigqokekayo ezihlakaniphile noma ibhethri ye-Lithium.
Kuma-monomers, kune-copolymer eyenziwe yi-Vinylidene fluoride (VDF) ne-hexafluoropropylene (HFP); kanye ne-terpolymer eyenziwe yi-Vinylidene fluoride (VDF), i-tetrafluoroethylene (TFE) ne-hexafluoropropylene (HFP). I-copolymer ye-FKM inokuqukethwe kwe-fluorine okungu-66% kungasetshenziswa ekusetshenzisweni okujwayelekile. Nakuba i-fkm terpolymer inokuqukethwe kwe-fluorine cishe u-68%, ingasetshenziswa endaweni enzima edinga ukumelana okungcono kwamakhemikhali/abezindaba.
Ngezinhlelo zokusebenza, i-FUDI inikezela ngokubumba, ikhalenda, amamaki e-extrusion fkm. Futhi sihlinzeka ngamamaki akhethekile afana nebanga eliphansi lokumelana nezinga lokushisa eliphansi le-GLT, okuqukethwe kwe-fluorine okuphezulu okuqukethe i-fluorine engu-70%, ibanga lokumelana nomusi kanye ne-alkali i-FEPM Aflas, ibanga elihle kakhulu lokumelana namakhemikhali perfluoroelastomer ffkm.
