Application

4,4'-(Hexafluoroisopropylidene)diphthalic anhydride, commonly referred to as 6FDA, serves as a crucial dianhydride monomer in the synthesis of advanced materials due to its unique mechanical and electrical properties. It plays a pivotal role in the development of polyamides for gas separation applications and is integral to the creation of colorless and transparent polyimides. 6FDA finds extensive use in the formation of thermally rearranged polybenzoxazole (TR-PBO) gas separation membranes, which are noted for their superior gas permeation selectivity and high permeability, particularly in H2/CH4 separation applications. In addition, this compound is a key raw material for producing thermoplastic fluorinated polyimide resin and is also employed in manufacturing polymers for electronic materials. The polyimides derived from 6FDA are particularly valuable for their use as substrates in wearable devices and as multilayer insulation materials, offering protection against space dust, cosmic rays, and satellite debris, thus contributing significantly to the advancement of aerospace and electronic industries.
