The complete set of polyimide building blocks — aromatic, fluorinated and alicyclic dianhydrides, diamines, fluorinated diamines, end-cappers and ester monomers. 100+ grades in total, with custom synthesis and scale-up available.
From mainstream dianhydrides such as 6FDA and BTDA to a full range of diamines, fluorinated monomers and end-cappers — covering nearly every building block used in polyimide synthesis. All 100+ grades are listed below; jump by chemical structure using the shortcuts.
Dianhydrides are the key building blocks of the polyimide backbone; their structure directly determines heat resistance, optical transparency and dielectric performance.
