Product Details

Discover Aure Chemical's High-Quality TFMB

TFDB (2,2'-Bis(trifluoromethyl)benzidine), also known as TFMB, is a fluorinated diamine monomer valued for its rigidity, aromatic structure, and electron-withdrawing trifluoromethyl groups. These characteristics position TFMB within the broader category of polyimide diamine monomers, commonly used as building blocks in advanced polymer synthesis.

The presence of trifluoromethyl substituents contributes to enhanced thermal stability, optical clarity, UV resistance, and reduced intermolecular interactions, which are frequently discussed in fluorinated polyimide material systems . As a result, TFMB is widely studied as a structural component in high-performance polyimide frameworks designed for thermally and optically demanding material environments.
