Applications of 2540-99-0
| Industry | Application | Process |
|---|---|---|
| Polymers | Synthesis of polyimide resins and films | Used to prepare high-performance polyimides via condensation polymerization with diamines (e.g., 4,4′-oxydianiline) in polar aprotic solvents (e.g., NMP, DMAC), followed by thermal imidization |
| Electronic Packaging | Substrate for flexible printed circuit boards (FPCs) | Processed into high-temperature-resistant, low-dielectric-constant insulating films via solution casting and gradient-temperature imidization |
| Aerospace | Component of high-temperature structural adhesives | Employed as an anhydride-type curing agent for epoxy resins or in combination with aromatic diamines in high-temperature adhesive systems, thermally cured at 150–250 °C |
| Optical Materials | Precursor for transparent polyimides | Copolymerized with low-dispersion diamines and subjected to controlled thermal imidization for flexible OLED display substrates and optical compensation films |
