DESCRIPTION
2,2'-Bis(trifluoromethyl)- [1,1'-biphenyl]-4,4'-diamine (TFDB/TFMB)
English Name: 5-Chloro-2-nitroaniline
CAS No.: 341-58-2
Molecular formula: C14H10F6N2
Molecular weight: 320.23
EINECS No.: 671-105-2
Application: 2,2 '- bis (trifluoromethyl) - 4,4' diaminobiphenyl is mainly used in the fields of microelectronics and optoelectronics. It is used to prepare PI materials with very low dielectric constant, very low surface free energy, very high mechanical strength, very high wear resistance, colorless and transparent. It is the most famous monomer among all fluorine-containing PI diamine monomers.
Typical Properties
Summary
Polyimide is an important monomer for the synthesis of polyimide. Polyimide synthesized with tfmb as monomer introduces fluorine group. Fluorine element has very small atomic radius and high electronegativity, which makes polyimide give it many unique properties while retaining excellent comprehensive properties, such as thermal stability, chemical inertia, excellent mechanical properties and so on.
