Application

4,4'-(Hexafluoroisopropylidene)diphthalic Anhydride, also known as 6FDA, serves as a versatile dianhydride monomer. Its primary purpose is to facilitate the synthesis of advanced polymers due to its remarkable mechanical and electrical properties. It is integral in the creation of polyamides derived from terphenylenes, which are essential for efficient gas separation processes. Moreover, 6FDA is instrumental in developing transparent and colorless polyimides, contributing significantly to industries requiring high-performance materials. It is employed in preparing thermally rearranged polybenzoxazole (TR-PBO) gas separation membranes, known for their excellent gas permeation selectivity and permeability, particularly benefiting hydrogen and methane separation. These membranes perform impressively, nearing the Robertson upper limit of 2008. Additionally, 6FDA is a critical component in producing thermoplastic fluorinated polyimide resin, further diversifying its application scope. Its utility extends to the production of polymers for electronic materials and polyimide materials, which serve as substrates in wearable devices and as multilayer insulation materials, offering protection against space dust, cosmic rays, and satellite debris. Through these varied applications, 6FDA plays a pivotal role in advancing both industrial and scientific innovations.
