What should be noted when using unidirectional polyimide film
2026-06-10Full precautions for using unidirectional polyimide (single pull PI) film The characteristic of unidirectional PI is anisotropy: the longitudinal MD (tensile orientation direction) has much better strength, modulus, flexural resistance, and thermal dimensional stability than the transverse TD; the transverse MD is prone to tearing, has higher elongation, and thermal expansion. The first pri
