The product is a truly fully soluble polyimide (PI) without the precursor - polyamic acid. The glass transition temperature (Tg) of the product is 320-330 °C, the temperature of thermal weight loss is about 525 °C, the intrinsic viscosity is 0.5-0.7dl/g (in NMP, 30 °C test), the product is 100% imidized, pure solid powder. At room temperature, it is soluble in common solvents. The dissolved concentration can reach more than 20%.

Due to the special solubility properties and very good temperature resistance (high glass transition temperature), and has very good chemical resistance beyond conventional polyimide, this product is especially suitable for high temperature coating and composite applications .
