Collection: Diamines [Polyimide Raw Materials]

Diamines [Polyimide Raw Materials] — includes aromatic diamine compounds with two primary amine groups on a biphenyl, naphthalene, or trifluoromethyl-substituted phenylene backbone, which act as monomers that form polyimide chains through polycondensation with dianhydride compounds.

Diamines [Polyimide Raw Materials] are used as raw materials for synthesizing polyimide films for flexible electronics, circuit substrates, and high-heat-resistant materials. Materials researchers and polymer engineers use variations in diamine structure, such as trifluoromethyl groups or biphenyl backbones, to tune the optical properties, solubility, and thermal stability of polyimides produced by polycondensation with dianhydrides.

Selecting a diamine should consider high purity free from impurity isomers, crystal or powder form, and the reactivity of the amine groups, which affects the molecular weight of the polyimide formed during synthesis. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
