Polyimide film is one of the earliest products of polyimide. It is used for slot insulation and cable wrapping material of motor.

The preparation method of thin film is: the polyamide acid solution flow is extended into film, and the high temperature imide is formed.
Yellow transparent film, relative density 1.39 ~ 1.45, with outstanding high temperature resistant, radiation resistant, resistant to chemical corrosion and electrical insulation performance, can be used in 250 ~ 280 ℃ air medium.
Glass transition temperature of 280 ℃ respectively Upilex (R), and 385 ℃ (Kapton) and above 500 ℃ Upilex (S).
The tensile strength of 200 mpa, when 20 ℃ 200 ℃ when more than 100 mpa.
It is suitable for the flexible printed circuit board and various insulation materials for high temperature resistance.
