UN IDs 2811 HS Code 2921590090 Hazard Note Toxic Hazard Class IRRITANT-HARMFUL2,2'-Bis(trifluoromethyl)benzidine (TFMB; TFDB) (CAS: 341-58-2) is used for producing a high strength flexible transparent polyimide material. Liquid crystal intermediate. 2,2'-Bis(trifluoromethyl)benzidine is an important monomer for the synthesis of polyimide. The polyimide synthesized with TFMB as the monomer introduces fluorine groups. The fluorine element has a small atomic radius and high electronegativity, which makes polyimide retain excellent comprehensive properties while giving it many unique properties, such as thermal stability, chemical inertness, excellent mechanical properties, etc. 2,2'-Bis(trifluoromethyl)benzidine is mainly used in the fields of microelectronics and optoelectronics to prepare extremely low dielectric constant, extremely low surface free energy, extremely high mechanical strength, extremely high wear resistance, colorless and transparent PI materials, and is the most well-known monomer among all fluorine-containing PI diamine monomers.
