High-modulus polyimide film is a kind of resin synthesized by a special formula. The high-modulus polyimide film produced by biaxial stretching process not only has the excellent comprehensive properties of ordinary polyimide film, but also has higher modulus and mechanical strength, lower shrinkage and lower thermal expansion coefficient.
Application: Products can be widely used in high-end electronic industry, high-precision flexible printed circuit board, aerospace and other industries.
