Application

4,4'-(Hexafluoroisopropylidene)diphthalic Anhydride, 98+ Percent, is chiefly used as a dianhydride monomer in the production of advanced polymers due to its remarkable balance of mechanical and electrical properties. Its primary purpose is to serve in the synthesis of polyamides and polyimides, particularly in applications requiring gas separation and the fabrication of polymers for electronic materials. This compound is integral in creating colorless and transparent polyimides, which are used as substrates for wearable technology and as multilayer insulation materials, offering protection against space dust, cosmic rays, and satellite debris. Moreover, it can be utilized with APAF to prepare thermally rearranged polybenzoxazole (TR-PBO) gas separation membranes, which are notable for their excellent gas permeation selectivity and high permeability, nearing the Robertson upper limit for H2/CH4 separation. Additionally, it is employed in the synthesis of thermoplastic fluorinated polyimide resins.
