Key Applications of BPDA

Electronics and Microelectronics: Employed in polyimide resins for super-engineering plastics in mobile phones, copying machines, and high-frequency components like 5G signal transmitters; also used in flexible printed circuit boards (PCBs) to prevent delamination due to matched CTE with copper, and in advanced semiconductor packaging for reliability under high temperatures.

Display Technologies: Utilized in flexible displays, leveraging thermal stability and mechanical properties for foldable and wearable devices.

Fibers and Textiles: Applied in the synthesis of high molecular weight aromatic polyamide fibers with high strength, modulus, temperature resistance, and radiation resistance.

Nanocomposites and Advanced Materials: Incorporated into polyimide/organic clay nanocomposites for superior tensile and thermal properties, hybrid nanocomposite films, and hyper-cross-linked polymers for dye wastewater purification.

Separation and Environmental Technologies: Used in fibrous membrane scaffolds for oil-water separation and in polymers for environmental applications like wastewater treatment.

Other Industrial Uses: Serves as a pharmaceutical intermediate and in the production of homo- and copolyimides for various high-performance applications
