IHazard Class IRRITANT-EYENZAKENI
I-2,2'-Bis(trifluoromethyl)benzidine (TFMB; TFDB) (CAS: 341-58-2) isetyenziselwa ukuvelisa amandla aphezulu aguquguqukayo e-polyimide ecacileyo.Ikristale yolwelo ephakathi.
I-2,2'-Bis(trifluoromethyl)benzidine yimonoma ebalulekileyo yokwenziwa kwepolyimide.I-polyimide edityaniswe ne-TFMB njengoko imonoma yazisa amaqela e-fluorine.Isixhobo se-fluorine sine-athomu encinci ye-athomu kunye ne-electronegativity ephezulu, eyenza i-polyimide igcine iipropathi ezigqwesileyo ngelixa inika iipropathi ezininzi ezizodwa, ezinjengozinzo lwe-thermal, ukunganyaniseki kweekhemikhali, iipropathi ezigqwesileyo zoomatshini, njl.
I-2,2'-Bis(i-trifluoromethyl) ibenzidine isetyenziswa ikakhulu kwimimandla ye-microelectronics kunye ne-optoelectronics ukulungisa i-dielectric ephantsi kakhulu, amandla asezantsi kakhulu asimahla, amandla omatshini aphezulu kakhulu, ukuxhathisa okuphezulu kakhulu, izinto ezingenambala kunye nezingafihliyo zePI, kunye yeyona monoma yaziwayo phakathi kwazo zonke ii-fluorine-eziqulathe ii-PI diamine monomers.
